Can't display some taxa's authorities

In Microcaldus and Fidelibacter pages, Microcaldota and Fidelibacterota's authorities can't be displayed because there is not enough parameters for speciesboxes. This needs to be fixed somehow. Jako96 (talk) 18:15, 31 May 2025 (UTC)

Wow, monotypic taxa so far up the hierarchy. So there would need to be provision for |greatgreatgreatgrandparent_authority=. Not a priority, but fixable if others think it worthwhile. Peter coxhead (talk) 21:01, 31 May 2025 (UTC)

A little surprising, right? Let's wait for others. And it is worthwhile, there is no other way around. Jako96 (talk) 21:05, 31 May 2025 (UTC)

I would say it is worthwhile. This is probably not the only time it will happen (Picozoa comes to mind). — Snoteleks (talk) 00:34, 1 June 2025 (UTC)

Wait, so there are monotypic class, order and family in Picozoa but they are not displayed because of this issue? Jako96 (talk) 07:45, 1 June 2025 (UTC)

No, the taxon is set to Picozoa and templates don' exist for other taxa. This could be changed by setting taxon to Picomonas and creating necessary templates.  —  Jts1882 | talk  09:17, 1 June 2025 (UTC)

I meant that, actually. Thanks. Jako96 (talk) 09:40, 1 June 2025 (UTC)

Jts, so do you think it's worthwhile? Jako96 (talk) 09:41, 1 June 2025 (UTC)

@Peter coxhead do you support my proposal too? Jako96 (talk) 20:14, 6 July 2025 (UTC)

Omg it's so funny. Even for this, we can't reach a consensus. Still, I have more problems with the automated taxobox system that I will try to get consensus in the future. We can't even solve this lmao. Jako96 (talk) 06:54, 9 July 2025 (UTC)

I changed automatic taxobox with a speciesbox in Picozoa page. Jako96 (talk) 10:10, 1 June 2025 (UTC)

I think it is worthwhile to allow |greatgreatgreatgrandparent_authority=. greatgreatgreatgrandparent_authority is sufficient to cover parents from species up to phylum, and there are single species phyla. I don't think single species kingdoms are likely. Plantdrew (talk) 14:38, 9 July 2025 (UTC)

@Peter coxhead You have the permission and I think you should make the change already. I support it, Snoteleks supports it, Plantdrew supports it, and CiaPan supports it too but he proposed to change the name (see Wikipedia talk:WikiProject Tree of Life#How about reducing greatgreat?). Jako96 (talk) 09:14, 11 July 2025 (UTC)

The flow of control is Template:Automatic taxobox, Template:Speciesbox, etc. → Module:Automated taxobox.automaticTaxobox() → Template:Taxobox/core → Module:Autotaxobox.taxoboxList(). The last is where the taxon names and authorities are actually shown in the taxobox. All of these would need to be altered, which is a non-trivial task, fraught with risk because of the massive usage of these modules and templates. It needs an editor with significant uninterrupted time available (which I don't have at present).

There's also the issue of whether there's a more generic solution, albeit somewhat more complicated, using parameters of the form greatNgrandparent_authority or something similar as per the comment below. This should be settled first, with agreement on exactly what parameter names to use. Peter coxhead (talk) 06:42, 14 July 2025 (UTC)

My vote is in favor of parentN_authority. It's intuitive and reminiscent of the original one, without the confusion of greats and grands. — Snoteleks (talk) 17:25, 14 July 2025 (UTC)

@Snoteleks: So parent1_authority would be a synonym of parent_authority, parent2_authority of grandparent_authority, etc.? Peter coxhead (talk) 20:07, 14 July 2025 (UTC)

Yes! That's how I envisioned it — Snoteleks (talk) 20:20, 14 July 2025 (UTC)

I also support that. This was the thing I was gonna propose. But I don't know if we should use parent1_authority or parent_authority. Jako96 (talk) 20:49, 14 July 2025 (UTC)

@Peter coxhead Is it possible to make parent_authority synonymous with parent1_authority? Like how in {{Citation}} the parameters first and first1 do the same? — Snoteleks (talk) 02:05, 15 July 2025 (UTC)

Absolutely.

(Initially I wrote that some aliases are already supported, because either underscores or spaces are allowed in parameters, so that e.g. parent_authority and parent authority are aliases. However, when I checked, I found that underscores or spaces are still ok in {{Speciesbox}}, but the underscore versions were enforced in {{Automatic taxobox}} via this set of edits, which should be fixed unless there was a consensus for this change.)

Allowing aliases for the existing authority parameters in all taxobox templates that support them is straightforward if a bit tedious to implement, since e.g. parent3_authority would just be passed on as greatgrandparent_authority, which has support in Module:Automated taxobox, Template:Taxobox/core and Module:Autotaxobox, so they wouldn't need changing. It's adding new levels of authority that is more tricky. Peter coxhead (talk) 09:03, 16 July 2025 (UTC)

I dislike aliased parameters. Spaced parameters aren't really being used in taxoboxes, although they do work. I'm not sure if spaced parameters are functional in any other infobox templates (I have tested {{Infobox settlement}} and {{Infobox person}}, and spaced parameters are not functional with those).

I don't know anything about the principles of good user interface design, so I'm not sure if it is a good thing to make some variations in syntax work (space vs. underscore in taxoboxes) or a bad thing to make variations in syntax work, but not universally (taxoboxes vs. other infoboxes).

Numbered parent authorities are less tied to English (rebisabuelo is Spanish for great-great-grandfather, not bisbisabuelo or rereabuelo), but I think most taxoboxes on other language Wikipedias have not translated the parameter names. Regardless of whether the parameters are translated or not, I wouldn't expect any other language Wikipedias to change their parameters to numbered parents if we do that here.

I do think numbered parent authorities would have been a better way to go if that had been done since the beginning, but I don't very much like the idea of having two systems (numbered/greatgreat) with aliases. I'd be on board with numbered parents if a bot could change everything over. Plantdrew (talk) 21:04, 16 July 2025 (UTC)

Like Plantdrew, in general I'm not keen on aliased parameters; for one thing they make maintenance more difficult. There is, I think, a possible case for space versus underscore aliases, because of their widespread equivalence in other contexts. However, for consistency we should either allow them in all taxobox templates or none, rather than in only some as at present.

I do agree that we should avoid aliased numbered and greatgreat.. parameters. Just because it's possible doesn't mean it's a good idea. Peter coxhead (talk) 08:33, 17 July 2025 (UTC)

I am slowly working up the call chain adding support for greatgreatgreatgrandparent_authority. I've reached the sandbox version of Template:Taxobox/core. As I noted above, although each step is straightforward, the templates and modules involved are very widely used, so I'm going slowly, including adding and checking new test cases. Peter coxhead (talk) 13:58, 22 July 2025 (UTC)

{{Speciesbox}} now supports |greatgreatgreatgrandparent_authority= as at Microcaldus.

Aside: It turns out that {{Speciesbox}} has accepted greatgreatgreatgrandparent_authority since 2011. Then it was used to deal with a subgenus being included in the taxobox, and was passed on as one level less, i.e. as greatgreatgrandparent_authority. In December 2018, I revised the way levels between species and genus were handled, and mistakenly passed on greatgreatgreatgrandparent_authority, which was then ignored by {{Taxobox/core}}.

I did some work towards getting {{Automatic taxobox}} to support this parameter, but on reflection I'm not sure that it's needed. {{Speciesbox}} now allows the authority to be given for the species, genus, and four levels above. When the target of {{Automatic taxobox}} is the genus, greatgreatgrandparent_authority reaches the same four levels above the genus.

Peter coxhead (talk) 08:50, 23 July 2025 (UTC)

Nice! I also updated Fidelibacter and Picozoa. Jako96 (talk) 10:20, 23 July 2025 (UTC)

I find myself asking why it is necessary to specify the authorities for parent etc. taxa in the speciesbox (etc), rather than storing the authority in each node, and picking up from there when needed. It's not a trivial change anymore with tens (hundreds?) of thousands on taxobox templates, but would it be possible to make authority an optional parameter at each node, and use it when it is present?

One could in principle code and run a bot to insert authorities in nodes, but I guess one would worry about the risk of something going wrong. Perhaps a bot that just deals with the nodes above one terminal; if that goes wrong there's only a few nodes that need repair. And the bot could terminate when it hits a node with an authority present. (Usall could manually populate the top 1000 or so boxes by usage.) Lavateraguy (talk)

@Lavateraguy: this has been discussed before I'm pretty sure (though I can't find where offhand).

The major problem is that we only do this for monotypic taxa. Whether a taxon is monotypic can't be determined from taxonomy templates, since child templates may not have been created yet.

My recollection is that another issue was a degree of inconsistency between sources as to the authority, and editors' reluctance to pick one standard source for each taxonomic group. My experience is that for plants even PoWO and IPNI don't always agree, particularly for things like ex authors, even though they supposedly share databases. For animals, it's more difficult, since there are no standardized ways of representing authors' names.Peter coxhead (talk) 12:31, 23 July 2025 (UTC)

Can confirm that the infrastructure setup at Kew is a bit weird in ways that I don't understand: Rafaël definitely makes fixes to authorities etc. in POWO (typically addition of parenthetical authorities) that don't immediately get back-ported into IPNI. Choess (talk) 13:25, 23 July 2025 (UTC)

Candidatus discussion

@Peter coxhead: @Snoteleks: @Plantdrew: Guys, it looks like the problem is NOT solved for Candidatus taxa, after the changes I made. See Candidatus Hodarchaeum. Jako96 (talk) 15:20, 27 July 2025 (UTC)

NOTHING has been solved for Candidatus taxa, including the question of whether to even have articles for most of them (they don't meet the requirements of WP:NSPECIES), and the question of how to title articles if we have them (include Candidatus in the title, or not? Most articles on Candidatus taxa don't include it in the title). Once those questions are solved we can address how taxoboxes should work for Candidatus taxa

Peter coxhead said he wasn't going to enable |greatgreatgreatgrandparent_authority= for {{Automatic taxobox}} (reasoning that it would need one less parent level than {{Speciesbox}}). Candidatus Hodarchaeum is using Automatic taxobox with |binomial_text= and |genus_text=. I'm surprised to see at Candidatus Hodarchaeum that |authority= is functioning to fill in the authority for the binomial. I would have expected |authority= to fill in the authority for the taxon called by |taxon=.

|binomial_text= is mostly used in articles for undescribed species with a provisional designation, to keep the provisional designation unitalicized. These don't have authorities, which I guess is why it wasn't aware of how the authority parameter behaved with binomial_text.

|genus_text= is used in only 17 articles. 10 of those are Candidatus taxa, and the others are mostly case of uncertain generic assignment. Uncertain generic placement has mostly been dealt with by using taxonomy templates with a query (e.g. Template:Taxonomy/Amia/?). Do we need |genus_text= for uncertain generic placement? Is |genus_text= a good way to handle Candidatus taxa? The "_text" parameters are intended to handle a small number of unusual cases. I don't think "_text" should be used for the large number of articles on Candidatus taxa, but a solution is needed for those. Plantdrew (talk) 19:08, 27 July 2025 (UTC)

I agree with Plantdrew that the key issue is the status of Candidatus taxon names and corresponding articles. These names depart from the standard rules of biological nomenclature so don't fit into the automated taxobox system, which expects uninomials at genus level and above, binomials for species, etc. If Candidatus Hodarchaeum were a normal monospecific genus, then a Speciesbox would be used, but it can't be because the first word of the species name isn't the genus. A possible way forward would be to have new "Candidatus autotaxobox" and "Candidatus speciesbox" templates, but I don't think this is worthwhile, and I have no interest in working on it.

@Plantdrew: I think the principle is that when |binomial_text= is used in an Automatic taxobox, the target taxon is then the species, so this is what |authority= applies to. Otherwise there would need to be |child_authority= to go down from the genus to the species. Peter coxhead (talk) 22:20, 27 July 2025 (UTC)

In case we need feedback for that issue, I disagree with putting Candidatus on titles. From an encyclopedic standpoint, it is as irrelevant in the title as the authority of an accepted taxon; that's my perspective. — Snoteleks (talk) 00:58, 28 July 2025 (UTC)

In my opinion, I don't think articles should need to have "Candidatus" in the page name; can't we just use the {{DISPLAYTITLE:}} template to add "Candidatus" in the title (as well as the double quotes for uncertain designations or whatever that's called, plus italicization of scientific name)? @Snoteleks @Peter coxhead

@Snoteleks: {{DISPLAYTITLE:}} can only change the formatting of a page title; the text must match exactly. Peter coxhead (talk) 15:37, 8 August 2025 (UTC)

Or better yet, how about a new template that is more appropriate that could to do that? With parameters like:

Parameters	Purpose
|candidatus=	to set whether or not the subject is a candidate taxon
|valid=	to set whether or not its name is tentative (double quote marks)
|scientific=	to set whether or not the article's name/title is a genus/binomial name (italicization)

Can't tell if this table is even working. Seems like posting on mobile is always whack.

CheckNineEight (talk) 08:43, 8 August 2025 (UTC)

@CheckNineEight: I'm not aware of any way of changing the characters in a page title. The formatting (e.g. italic) can be changed using {{DISPLAYTITLE:}}, but you can't add " or Candidatus with a template. Peter coxhead (talk) 15:41, 8 August 2025 (UTC)

{{Italic verbatim title}} adds " and italicizes the entire title (except for a parenthetical disambiguation). There are some other templates that modify the title listed in the documentation for {{Italic verbatim title}}. Plantdrew (talk) 16:08, 8 August 2025 (UTC)

I think we should either add these parameters to existing templates or create a new template for Candidatus taxa. Jako96 (talk) 08:49, 9 August 2025 (UTC)

Same. I just realized, though, that the parameter names I gave might cause confusion; let's think of better names for these. CheckNineEight (talk) 11:13, 9 August 2025 (UTC)

I think we just need the "candidatus" parameter. Right? Jako96 (talk) 12:53, 15 August 2025 (UTC)

I'm not sure what you mean. I'm only sharing ideas/suggestions. I guess "candidatus" is actually a good enough name for the parameter, but I don't know what template you guys have decided to add it to; though if you ask me, I think it's a good idea to have a new template with all three parameters/settings, and it'd be nice to have it automate-able for automatic updates, like what the IAbot and Citation Bot does to {{Citation}} templates. CheckNineEight (talk) 13:48, 15 August 2025 (UTC)

We would add the "candidatus" parameter to Template:Automatic taxobox, Template:Paraphyletic group, Template:Speciesbox and Template:Subspeciesbox. Jako96 (talk) 14:50, 15 August 2025 (UTC)

Those templates can modify the display title, too? (Genuinely don't know about this) CheckNineEight (talk) 14:54, 15 August 2025 (UTC)

These 4 templates can't change how the title appeares for now. But this can be changed, of course. Jako96 (talk) 15:04, 15 August 2025 (UTC)

Alrighty CheckNineEight (talk) 15:24, 15 August 2025 (UTC)

So what do you think about the "candidatus" parameter, @Peter coxhead, @Snoteleks and @Plantdrew? Jako96 (talk) 16:40, 15 August 2025 (UTC)

Personally I am against having "candidatus" in the title, but perfectly fine with having it displayed in the taxobox, kind of like the exinct parameter. — Snoteleks (talk) 17:01, 15 August 2025 (UTC)

Interesting idea. I can see how a "candidatus" parameter could add something to the beginning of the name (as the extinct parameter does). However, we may have "candidatus" at a multiple ranks. The extinct parameter works at a single rank (typical use case is an extinct species in a extant genus), with extinction at other ranks specified in taxonomy templates. Would candidatus be a parameter in taxonomy templates to cover multiple ranks? Plantdrew (talk) 18:02, 16 August 2025 (UTC)

I think this is a good idea Jako96 (talk) 18:20, 16 August 2025 (UTC)

If this can be automated, that would be great; it'd be nice if the candidate status of a taxon and lower ranks can update as soon as a species in this lineage loses that status (and sister taxa within this lineage remains "Candidatus" while all species within them remains so). CheckNineEight (talk) 00:13, 17 August 2025 (UTC)

By the way, I forgot about Template:Taxobox. Jako96 (talk) 17:14, 15 August 2025 (UTC)

I forgot! Automatic taxobox (and maybe more taxobox templates) CAN change how the title looks. See Lomosovis for example. Jako96 (talk) 13:19, 6 September 2025 (UTC)

@Jako96: so the page would be at the 'plain' name, and then |candidatus=yes would add "Candidatus" to the taxobox display – is that the idea? (Personally I think the candidatus nomenclature is an abomination, but we appear to be stuck with it.) Peter coxhead (talk) 16:54, 15 August 2025 (UTC)

Yes. But I think we should probably also have "Candidatus" in the title of the page. Jako96 (talk) 17:11, 15 August 2025 (UTC)

Again, personally I would never add that to the title. But I'm not enough into prokaryotes to be an authority here, so do not consider me for this. — Snoteleks (talk) 17:52, 15 August 2025 (UTC)

We want to stop naming our articles Candidatus [taxon name], but we still need to show "Candidatus" on the display title to let the readers know that the taxon does not yet have any cultured strains. Kinda important, to hopefully give readers the idea that the species they're reading about (or that is/are within the higher taxonomic rank they're reading about) is barely known about beyond just metagenomic analyses (and, if they're lucky, proteomic and/or microscopy analyses also). CheckNineEight (talk) 23:47, 15 August 2025 (UTC)

But why does that need to be in the title, just out of curiosity? There's plenty of eukaryotic species that are so poorly known there's only one 19th century drawing of them, or a fossil. But you never see nomen nudum or † in the title. Why can't that simply be in the taxobox alone? — Snoteleks (talk) 00:35, 16 August 2025 (UTC)

Actually, you're right. We don't need to display Candidatus in the title. Anyway, there is another problem. Will the quotes on the taxobox be in bold? Currently, we do use quotes in bold in text, and also in taxoboxes, but the quotes on Template:Life on Earth do not appear bold in pages. Jako96 (talk) 06:45, 16 August 2025 (UTC)

See Candidatus Aenigmatarchaeum for example. Jako96 (talk) 06:49, 16 August 2025 (UTC)

I changed my mind again. I think we should display Candidatus in the title. Because in text, we will be using the word Candidatus for such taxa anyway. For example, we will use "Candidatus Thorarchaeia" in text, not "Thorarchaeia". Jako96 (talk) 09:07, 16 August 2025 (UTC)

If you want Candidatus in the title, move the page to that title (after getting consensus for the change). The taxoboxes can only add formatting to the title, not change the characters.

Adding candidatus to the taxoboxes in the taxon name is ugly, especially when bolded as in Candidatus Hodarchaeum. It might be better not bold the "Candidatus" or move it to the rank column.  —  Jts1882 | talk  11:43, 16 August 2025 (UTC)

@Jts1882: I couldn't agree more strongly that the taxobox at Candidatus Hodarchaeum is ugly, but this is the fault of the nomenclature system, which the taxobox reflects; see the LPSN entry. Peter coxhead (talk) 17:10, 16 August 2025 (UTC)

It is indeed, ugly. But we can just write "Ca." instead of "Candidatus", if you want. Jako96 (talk) 09:18, 17 August 2025 (UTC)

I'm not an expert on this, but I think the term Candidatus was, if I recall correctly, made specifically for the fact that prokaryotes are, not only hard to be observed alive, but also hard to isolate and grow (culture)... unlike the term nomen nudum. "Candidatus" indicates that much of what is known about this cell is just its relationship with other taxa (phylogeny, and maybe even its environmental and pathogenic effects) and its' description/characterization is, overall, purely theoretical and subject to further characterization/identification and even changes; "nomina nudum" is a designation specifically for multicellular organisms, and it's equivalent to adding double quotes [" "] around the taxon name. CheckNineEight (talk) 07:38, 16 August 2025 (UTC)

How about this as a solution? We treat the Candidatus taxa the same way we treat extinct taxa.

• We add a |candidatus= parameter to the taxonomy templates.
• We add Ca. before the taxon name in the taxobox, just as we add † for extinct taxa (incidentally should the † be linked?)
• While adding parameters to the taxonomy templates hasrin't been done almost since the inception, I think this would be easy to implememt in Module:autotaxonomy.

Thoughts?  —  Jts1882 | talk  10:36, 18 August 2025 (UTC)

How about a legend at the top of the list? That way, you don't have to hyperlink every instance of Ca. or † beside the taxon names.

Ca. – Candidatus

† – extinct CheckNineEight (talk) 23:42, 18 August 2025 (UTC)

@Jts1882: it's a bit more tricky than †, at least if the result is to be like the taxobox here but with "Ca." rather than "Candidatus", because no name is italicized regardless of rank, and double quotes are added. Peter coxhead (talk) 09:20, 19 August 2025 (UTC)

Also, this parameter should be only for genera and species because sources use only quotes on higher Candidatus taxa and use the word Candidatus on only genera and species (we would obviously state in text that a higher taxon is Candidatus). See this article for example. Even before adding such a parameter, I think we should now change such taxa's names in the wiki (for example "Ca. Hodarchaeales" would be written as "Hodarchaeales"). Who agrees with me? Jako96 (talk) 22:33, 20 September 2025 (UTC)

Just so we're clear – and this was what I've been saying, by the way:

• Pagenames should not have "candidatus" in it (because that adds extra work of having to move the page once the species/genus loses its candidate status, among other reasons).
• "Candidatus"/"Ca." should still be seen somewhere in the article itself, like in the taxobox at the very least.
• Use "candidatus"/"Ca." sparingly in the main body text, if at all.

I say we should move the pages now to their straightforward name counterparts (ones that don't begin with "Candidatus"). Also, the |candidatus= parameter should definitely be implemented as a {{Taxonomy}} template feature, similar to |extinct=; make it so that the taxobox system adds "Ca." for genus and species taxa with |candidatus=yes, and quotation marks for taxa in higher ranks. CheckNineEight (talk) 01:06, 21 September 2025 (UTC)

No, the parameter shouldn't add quotes for higher ranks, we could just add quotes using taxonomy templates for now. Because, taxa such as the proposed superclass "Methanomada" are not Candidatus but just invalid and should be in quotes. Also, do you agree with me changing names like "Ca. Hodarchaeales" to "Hodarchaeales" in the wiki and move pages like Candidatus Wenzhongarchaeales to Wenzhongarchaeales now? By the way, we should probably keep Candidatus in the title for genera and species because some genera and species are commonly only mentioned as "Candidatus ..." or "Ca. ...", but I'm not sure. Jako96 (talk) 09:00, 21 September 2025 (UTC)

We should move all pages, including genus and species; that's why I proposed for some way to somehow add "Candidatus" to the display title: for articles that don't have it in their page name, but should definitely have it on their title otherwise.

I get that there's the alternative solution of just {{DEFAULTSORT}}ing these pages so that they don't overpopulate section C of alphabetical lists, but I'm personally not a fan of that. CheckNineEight (talk) 23:13, 21 September 2025 (UTC)

I meant we should also not use the word Candidatus in text for higher taxa (ofc we should state in text that they are Candidatus but for example we would normally say "Hodarchaeales" instead of "Candidatus Hodarchaeales" for higher taxa). Do you support this now? I'll change them all, if you do. Jako96 (talk) 15:03, 22 September 2025 (UTC)

Yeah, I guess. I personally wouldn't repeat writing it after having already done it once in the lead section, at least; as long as it shows up where it makes sense and when it matters – and it seems like it only matters for genus and species. CheckNineEight (talk) 16:04, 22 September 2025 (UTC)

Thanks for agreeing! Higher taxa will not have the word Candidatus anywhere in the wiki but in text, it will be mentioned because this is what most quotes-using sources do. Anyway, I'll start with this sometime. Jako96 (talk) 16:11, 22 September 2025 (UTC)

I moved every page with the word Candidatus in title that I can move and used Template:Db-move on a lot of redirects to get others also moved. I'll also edit articles soon. Jako96 (talk) 16:25, 23 September 2025 (UTC)

I edited some articles and moved all the pages, I'll continue on editing. Jako96 (talk) 13:33, 24 September 2025 (UTC)

I've added some rules to WikiProject Microbiology, see. Jako96 (talk) 18:08, 24 September 2025 (UTC)

By the way, @CheckNineEight, earlier you said that a taxon loses the Candidatus status as soon as one of it's members gets cultured, right? Well, this is not the case. Names such as "Asgardarchaeota" are still technically Candidatus, even though Promethearchaeum is a cultured archaeon. A name can't lose it's Candidatus status, a different name has to be published. Jako96 (talk) 18:20, 24 September 2025 (UTC)

Thanks for letting me know. CheckNineEight (talk) 00:20, 25 September 2025 (UTC)

You're welcome! One last thing: If someone proposes the name "Asgardarchaeota" in a different rank, for example, class, the name would be valid under the ICNP. Jako96 (talk) 13:37, 25 September 2025 (UTC)

Now, do you think we should wikilink like this; "Ca. Lokiarchaeum", like this; "Ca. Lokiarchaeum" or like this; "Ca. Lokiarchaeum"? Jako96 (talk) 15:23, 26 September 2025 (UTC)

The second one. For the sake of saving bytes, it's better to do it like "''Ca.'' [[Lokiarchaeum]]" instead of [[Lokiarchaeum|"''Ca.'' Lokiarchaeum"]] or "[[Lokiarchaeum|''Ca.'' Lokiarchaeum]]"; only hyperlink the words that are all parts of the page name.

I suppose redirects were made, for when [[eukaryote]]s (hyperlink spells "eukaryotes" while still pointing to eukaryote) becomes [[eukaryotic]] (redirects to eukaryote). CheckNineEight (talk) 20:47, 26 September 2025 (UTC)

Forgot to reply you here, yes, we should not link Candidatus, I agree. Jako96 (talk) 21:59, 26 October 2025 (UTC)

I am in favor of what you've been saying @CheckNineEight, we should move pages to non-Candidatus page names and just find alternative ways to display Candidatus in the title, if at all. — Snoteleks (talk) 14:54, 22 September 2025 (UTC)

Request for consensus on "Species described in (year)" categorization

How should we deal with synonyms and new combinations when categorizing them? Example: the species Apoikia lindahlii (2010) is a new combination from the basionym Monas lindahlii (1956). As I understand it, the purpose of "species described by year" categories can either be:

1. To categorize new species, in which case the article Apoikia lindahlii would belong in Category:Protists described in 1956 and the redirect Monas lindahlii would not be categorized.
2. To categorize new names, in which case the article Apoikia lindahlii would belong in Category:Protists described in 2010 and the redirect Monas lindahlii would belong in Category:Protists described in 1956.

Since I haven't seen consensus on which of these options we are following as a WikiProject, I thought I should ask. Personally, I veer towards the 1st option, as it serves a statistical purpose for seeing how many species are described each year. — Snoteleks (talk) 18:09, 6 September 2025 (UTC)

If you work your way up the category hierarchy, you get to Category:Species by year of formal description, which to me makes it clear that the 1st option is correct. For plants, there's guidance at WP:WikiProject Plants/Description in year categories which includes examples, clearly supporting the 1st option. Peter coxhead (talk) 19:53, 6 September 2025 (UTC)

Perfect, thanks! That means I have been doing it incorrectly for a lot of taxa, so I will have to fix them — Snoteleks (talk) 20:27, 6 September 2025 (UTC)

@Peter coxhead And I assume the Category:Taxa by author is meant for the 2nd option, right? — Snoteleks (talk) 22:31, 6 September 2025 (UTC)

@Snoteleks well, for plants I can only say that my experience is that it's the first namer, so if the authority is "(X) Y" the article goes at "Category:Taxa named by X". For examples, look at Banksia armata or Chordifex dimorphus.

This would be even more clearly the case, I would expect, for ICZN taxa, because in the ICZN the name is firmly attached to the original author - a recombination or change of rank isn't recognized in the authority at all. Panthera leo (Linnaeus, 1758) isn't a new name, it's just a new combination. The specific name is leo whose author is forever Linnaeus, regardless of whether the combination is Felis leo or Panthera leo. Peter coxhead (talk) 17:08, 7 September 2025 (UTC)

@Peter coxhead Understood, thanks for your input — Snoteleks (talk) 18:03, 7 September 2025 (UTC)

Where this is ambiguous is taxa that have had a replacement name assigned. Technically, species X might have been described in 1885, but given a new name in 1985 when it was recognized as a junior homonym, and given that the category uses the term "described" I would advocate sticking with the original year of description. Giving a taxon a new name does not involve a new description of that taxon. That said, a new replacement name is not the same as a junior synonym that is used as a replacement name when the homonym becomes invalid. That name does have an independent description, so that very specific situation (a junior synonym replacing a homonym) is the one that might be contentious. Dyanega (talk) 18:16, 7 September 2025 (UTC)

Seems like we are all in agreement so far that option 1 is preferable when categorising by year of description, per the name of the category. I do see value in categorising synonym redirects, especially for heterotypic synonyms, but for the article representing the accepted taxon I think we should reflect the earliest description of the taxon rather than any of its names.

I have always found the Category:Taxa by author categories somewhat problematic for using the term "named" instead of "described" and would like to see these changed, as I think the current naming convention is somewhat out of touch with the way these categories are actually used (that is, the way Peter coxhead describes). Ethmostigmus 🌿 (talk | contribs) 02:40, 8 September 2025 (UTC)

@Ethmostigmus: I agree that "named" isn't a good term, one reason being that what counts as a name varies among the nomenclature codes (as noted above, in the ICZN, leo in Panthera leo is the specific name, whereas in the ICNafp, armata in Banksia armata is not a name, but the specific epithet). Using "described" would be better, provided it is clear that it means "first described". Peter coxhead (talk) 15:03, 8 September 2025 (UTC)

Correct spelling of Bubalus wansjocki/wansijocki

I'm not sure what the correct spelling is for an extinct Chinese buffalo species. Wikipedia and PaleoBioDB use Bubalus wansijocki, while most of the scientific literature seems to use the spelling Bubalus wansjocki [1] [2]. The original publication where the species was named M. Boule, H. Breuil, E. Licent, P. Teilhard de Chardin "Le Paleolithique de la Chine" Masson et cie, Editeurs, Paris (1928) is obscure and hard to get hold of.

Any objection to

... me starting a category:Fungal taxa named by Carl Linnaeus? It would be a subcat of category:Botanical taxa named by Carl Linnaeus. It's of personal interest to me, because I'd like a listing of the Wikipedia articles about fungi described by Linnaeus, and I can't think of any other way of obtaining this than going through the above cat and finding them myself; and if I'm going to do this anyways, I might as well make these search results available for all. No, I don't plan to do this for any other authorities, but obviously Linnaeus is a special case. For background, I'm working on an article List of lichen taxa named by Carl Linnaeus (recommendations for a less bulky title gratefully accepted), which will have about 80 species; I'd like to know what the numbers are for a similar potential list for fungi.

May I suggest List of lichens named by Linnaeus? Or is that overly simplified? — Snoteleks (talk) 16:15, 30 September 2025 (UTC)

Well, there's Carl Linnaeus the Younger, but I like the "lichen taxa"->"lichens" shortening. Esculenta (talk) 16:21, 30 September 2025 (UTC)

 Done I found out from another source that Linnaeus only described about 150 fungi in total (back in the day, fungi were relegated to the "Cryptogamia" along with ferns, mosses, and algae, since they lacked visible flowers), so we're not terribly far off from a "complete" representation of his fungal work.

Et al.: italics, or not italics?

Should "et al." be italicized in taxon authorities? I haven't seen any policy on this topic and I have come across both editors that enforce italics and editors that enforce not using italics. — Snoteleks (talk) 10:39, 25 October 2025 (UTC)

I've added a fair number of et al. taxon authorities lately without italics. But only because it is slightly easier; I don't have any strong opinion about whether et al. should be italicized. Existing relevant guidance is at Wikipedia:Manual_of_Style/Text_formatting#Non–English_language_terms, but et al. isn't explicitly mentioned. There is an extensive analysis at Wikipedia_talk:Manual_of_Style/Abbreviations/Archive_5#Revisiting_et_al., but there are no comments aside from the original poster. Plantdrew (talk) 16:59, 25 October 2025 (UTC)

Without reading that extensive discussion, my impression from past discussions was that Wikipedia favours no italics. I remember this because I think there should be italics. The CS1/CS2 citation templates don't italicise, so for consistency no italics does make some sense.  —  Jts1882 | talk  17:06, 25 October 2025 (UTC)

I think the argument is that "et al." is like examples at MOS:NONENGITALIC such as "e.g.", "i.e." and "etc." In particular, if "etc." is not italicized, then why should "et al." be? Peter coxhead (talk) 17:00, 26 October 2025 (UTC)

I also now recall US editors appealing to whether a term is italicized in example sentences in Merriam-Webster. If you look at the example sentences in the entry for "et al.", then "et al." is not italicized. Compare this with, say, the example sentences in the entry for "ipso facto" where this term is italicized. Peter coxhead (talk) 17:14, 26 October 2025 (UTC)

Official nomenclature:

• International Code of Zoological Nomenclature: italicized (Article 51.2.)
• International Code of Nomenclature for algae, fungi, and plants (Shenzen Code) (I do not expect a change in the latest Madrid Code): not italicized (Recommendation 46C.2.)
• International Code of Nomenclature of Prokaryotes. Prokaryotic Code (2022 Revision): italicized (Rule 33b)
• The International Code of Virus Classification and Nomenclature: not applied as a rule. --Petr Karel (talk) 10:28, 27 October 2025 (UTC)

Ancyromonadida

Right now, the order Ancyromonadida is assigned to the monotypic class Planomonadea in the automated taxobox system. I recently made some changes to assign Ancyromonadida directly to the domain Eukaryota, which @Snoteleks reverted. He's saying that in the Cavalier-Smith, 2022 paper, Cavalier-Smith assigned the order Planomonadida, which is a synonym of Ancyromonadida; to the monotypic class Planomonadea, so, we should do this for Ancyromonadida because this is the name that we use. I said that this was WP:OR, since no source assigned Ancyromonadida to Planomonadea, but he didn't agree with me (see these: https://en.wikipedia.org/w/index.php?title=Ancyromonadida&action=history, https://en.wikipedia.org/w/index.php?title=Template:Taxonomy/Ancyromonadida&action=history, https://en.wikipedia.org/w/index.php?title=Template:Taxonomy/Planomonadea&action=history and User talk:Snoteleks#About Ancyromonadida situation).

So, thoughts? Who thinks this is WP:OR and who does not? Should the Ancyromonadida still be assigned to Planomonadea in the wiki? Jako96 (talk) 20:48, 27 October 2025 (UTC)

Pseudofungi-oomycete-bigyromonad mess: two proposed solutions

Context: the clade Pseudofungi is usually considered to contain three clades, oomycetes, bigyromonads and hyphochytrids. Main issue: the taxonomic ranks of these four taxa are inconsistent across papers, and there is no strict ranked classification with all of them (see more detailed context in this previous discussion). I propose two completely different solutions to bring harmony to our taxobox system while keeping the content accurate and not following an obsolete system:

1. Pseudofungi as a clade above phylum-level. This would mean it contains three phyla: Oomycota, Hyphochytriomycota, and Bigyromonadea.
   • Advantages: mycologists and oomycete specialists alike prefer Oomycota as a phylum/division over a class, and there is now majority support for its division into two classes, Saprolegniomycetes and Peronosporomycetes (plus several basal class-less orders).
   • Disadvantages: the Bigyromonadea are not cited as a phylum-level taxon in almost any paper. The author that described it, T. Cavalier-Smith, only ever considered it a class of Pseudofungi (or more frequently a subphylum of Gyrista, with the alternate spelling Bigyromonada). Just one paper cites it as a phylum.
2. Pseudofungi as a phylum-level clade. This would mean it contains three classes: Oomycetes, Hyphochytriomycetes, and Bigyromonadea.
   • Advantages: both subgroups of bigyromonads are two monotypic classes (i.e., each with their own order), making this an easy change: instead of Developea and Pirsonea, we can just use Developayellida and Pirsoniales directly. This is consistent with the Cavalier-Smith paper from 2006, in which bigyromonads were treated as a class of Pseudofungi instead of a subphylum of Gyrista.
   • Disadvantages: it goes against the mycological consensus stated above.

Pinging @Tony 1212 and @Jako96 since they contributed to the previous conversation about this topic, but of course I would like to know which choice is preferable among other editors. — Snoteleks (talk) 21:22, 27 October 2025 (UTC)

I agree with the second one, but is there a source that places the class Hyphochytriomycetes inside the phylum Pseudofungi? If not, then we should use the name Hyphochytrea. Jako96 (talk) 17:09, 28 October 2025 (UTC)

I prefer proposal 1: the advantages are strong (as stated) and go with consensus in the botanical field (the main group interested in these organisms it seems) and to my mind outweigh the stated disadvantage.

Bigyromonadea, being a zoological name, does not need to be formally established at any particular rank to be employed "somewhere/wherever" above family by whomever chooses to do so. Of course on Wikipedia we need published sources (1 is cutting it a bit fine) and not "original research" but we also need internal consistency across domains/kingdoms/whatever, something the published sources have failed to address in this case. My preference would be to use Bigyromonadea as a phylum in Wikipedia, noting perhaps that this is a "placeholder" solution pending a more permanent resolution (e.g. if there is ever a Ruggiero et al. v. 2.0 it could/should be addressed there). If it helps, "we" (IRMNG editors, now including 2 persons in this discussion) can make that change in IRMNG as well (not a peer reviewed source but citable in my view) and reference it in Wikipedia as needed.

That way, logic is maintained (Pseudofungi, as a superphylum perhaps) includes both Oomycota and Bigyromonadea (as well as Hyphochytriomycota (?)) as phyla), and Oomycota as a phylum can include its currently "accepted" classes Saprolegniomycetes and Peronosporomycetes (as per the current leading authorities in that area). Tony 1212 (talk) 18:47, 28 October 2025 (UTC)

Now I did some research, and I understood that the two classes Saprolegniomycetes and Peronosporomycetes are pretty much consensus. Also, since most sources don't care about ranks and just phylogenetics, Bigyromonadea, Developea and Pirsoniales are most mentioned in scientific articles (even though Bigyromonadea, normally a class-level name, can't include another class Developea). Ranking the Bigyromonadea as a phylum is a new thing though, but, since Wikipedia uses a Linnean classification, I do think we should use it. I agree with the first proposal. Jako96 (talk) 20:05, 28 October 2025 (UTC)

Wait, Snoteleks, you said that the source that uses the phylum Bigyromonadea uses the Oomycota phylum for both oomycetes and hyphochytrids, right? Then, I think we should use an unranked clade Bigyromonadea, because otherwise it would be WP:SYNTH. As I said, Bigyromonadea, Developea and Pirsoniales are most mentioned in articles because of phylogenetics, so, we should use the classes Developea and Pirsonea under the clade (not phylum) Bigyromonadea. Jako96 (talk) 20:26, 28 October 2025 (UTC)

@Jako96 We shall use whichever name is most common. — Snoteleks (talk) 19:54, 28 October 2025 (UTC)

For what it is worth... Hyphochytriomycota is treated as a phylum in Hyde et al., 2024, alongside Oomycota; same in MycoBank, https://www.mycobank.org/page/Name%20details%20page/field/Mycobank%20%23/90205 .

Bigyromonadea, established as a class, could remain so within a superphylum Pseudofungi (i.e. not be raised to a phylum, and unplaced within the superphylum) at least in IRMNG, probably also in Wikipedia if desired. From Cho et al., 2022: "Maximum likelihood analyses show Bigyromonadea related to oomycetes, whereas Bayesian analyses and topology testing were inconclusive. We observed similarities between the novel bigyromonad species and motile zoospores of oomycetes in morphology and the ability to self aggregate. Rare formation of pseudopods and fused cells were also observed, traits that are also found in members of labyrinthulomycetes, another osmotrophic stramenopiles. Furthermore, we report the first case of eukaryovory in the flagellated stages of Pirsoniales. These analyses reveal new diversity of Bigyromonadea, and altogether suggest their monophyly with oomycetes, collectively known as Pseudofungi, is the most likely topology of the stramenopile tree." Tony 1212 (talk) 05:51, 29 October 2025 (UTC)

We can't use a superphylum Pseudofungi, that would be WP:OR, as there is no such usage. And it's not "unplaced" in the Pseudofungi, there is just not a traditional phylum placement, and that's it. Jako96 (talk) 13:01, 29 October 2025 (UTC)

No, Snoteleks, that would be WP:OR. We can't use the name Hyphochytriomycetes if we are using the three-class system of Pseudofungi, there is no such usage. Jako96 (talk) 13:04, 29 October 2025 (UTC)

If fixing the Pseudofungi inner clades with the standard taxonomic ranks, I would prefer the lowest possible rank (this approach is often applied in classification by protistologists, see e.g. Adl et al. 2005,2012,2019), in this case orders or classes (and redirects from the higher levels). We should take into consideration, that there are several MAST clades (in Pseudofungi at least MAST-1, MAST-2, MAST-23, MAST-26), which, after discovery and cultivation of a representative, may destroy the "fixed" higher level hierarchy. --Petr Karel (talk) 09:34, 29 October 2025 (UTC)

I'm a bit confused with this discussion. Looking at other articles, are bigyromonads pseudofungi? The Stramenopile and Gyrista articles suggest not and in the taxonomy template system, Bigyromonada is a subphylum within clade Gyrista and Pseudofungi is ranked as a clade.

Could anyone provide a primary reference with the taxonomic diagnosis or cladistic definition of the Bigyromonada/Bigyromonadea? This must be the first step, later we could search for modified amendments in other studies. The reference in the article Bigyromonada (Cavalier-Smith, 2017) provides only diagnosis for the new inner classes Developea and Pirsonea, subphylum Bigyromonada is considered "probably paraphyletic", and Psudofungi is a different subphylum!

One could split a hair and point out that the diagnosis of "Class Bigyromonadea cl. nov." was invalid (illegitimate? unavailable? scarcely matters since names above family are not governed by any Code) on account of the basionym for the description being incorrectly cited, and/or that name post-dating the one in question, but I guess the intent is clear: they have the same definition, at least as proposed.

One non-trivial detail to know is that bigyromonads specifically never branch together in SSU-only analyses; only multigene or phylogenomic analyses recover them as a clade. This has already been discussed in papers. — Snoteleks (talk) 00:30, 31 October 2025 (UTC)

Chondrocladia robertballardi sp. nov.

Hi! I've just created an article for Chondrocladia robertballardi sp. nov. reported as being discovered in 2025. However, having dug into the sources some more, I'm now more confused than when I started. This is presented as a new discovery, but at the same time other sources suggest that there is a preexisting Chondrocladia robertballardi, discovered in 2015. Is this the same species in a new location, or a new species? Are they similar, or are they exactly the same?

Can anyone knowledgeable help clear this up, both here and at Wikidata? — The Anome (talk) 14:44, 1 November 2025 (UTC)

Those news reports are a bit unclear. My quick interpretation is that the Cristoba at al (2015) article described a new species, Chondrocladia robertballardi sp. nov. The sp. nov. suffix is a convention to indicate a newly described species and means the authors of that paper are authors of that species, which subsequently is referred to as Chondrocladia robertballardi Cristobo, Rios, Pomponi and Xavier, 2015 (link to entry at WoRMS). The new survey has found a new species in genus Chondrocladia, which is dubbed Chondrocladia sp. nov. because it hasn't been formally described and named. We shouldn't have articles until the species is described formally. I think your article should be moved to Chondrocladia robertballardi based on the species described in 2015. The new undescribed species could be mentioned at the genus article, Chondrocladia.  —  Jts1882 | talk  15:27, 1 November 2025 (UTC)

I've done some re-writing here, moving the new species to a section of the main article. I've also done some refactoring of entries in Wikidata, see https://www.wikidata.org/wiki/Q63718802 and https://www.wikidata.org/wiki/Q136684895 . There's a bit of confusion in Wikidata about parent taxa in the merge of the older discovery - can someone please check my work, both here and on Wikidata? — The Anome (talk) 16:12, 1 November 2025 (UTC)
