Mediorhynchus africanus Amin, Evans, Heckmann and El-Naggar, 2013[1] |
The species name africanus is named for the worm's distribution across sub-Saharan Africa.[1] It is synonymous with Empodius segmentatus (de Marval, 1902) Southwell et MacFie, 1925 and Mediorhynchus selengensis Harris 1973.[2] | The trunk is pseudosegmented, flattened laterally, has many prevalent sensory pits. There is marked sexual dimorphism with the female being much larger. There are up to 100 annuli (structures that permits shortening and lengthening of the body by telescoping) in females but fewer in the shorter males. The proboscis is divided by a prominent ridge into two parts: anterior and posterior. The anterior proboscis is pear or apple-shaped with a truncated bare apical end measuring 250 to 339 long by 278 to 478 wide in the male and 300 to 438 long by 330 to 510 wide in the female. The anterior proboscis has two prominent apical pores and 18 to 22 longitudinal rows of 4 to 6 hooks each. The hooks posteriorly directed and measure between 35 and 76 long with the smallest found anteriorly and the longest in the middle. The posterior proboscis is conically shaped and measures 291 to 332 long by 591 to 689 wide at junction with anterior trunk in the male, and 323 to 365 long by 99 to 745 wide at junction with anterior trunk in the female. Except for the posterior most end, the posterior proboscis is covered in very thin spines that are curved posteriorly or undulating with a total of 26 to 40 longitudinal rows of 2 to 6 spines each measuring 14 to 43 long with the longest spines found anteriorly. The Proboscis receptacle is single-walled with anterior portion encased in jacket of adjacent retractor fibers and measures 0.64 to 1.23 mm long by 0.11 to 0.44 mm wide in the male and 0.64 to 1.80 mm long by 0.11 to 0.55 mm wide in the female. The proboscis retractor muscles are prominent and attached to the proboscis receptacle near its posterior end dorsally. The lemnisci long, digitiform, unequal, and unattached. The shorter lemniscus measure between 1.60 and 3.38 mm long by 0.21 and 0.31 mm wide, with 5 or 6 giant nuclei in the male and measure 1.60 to 5.50 mm long by 0.19 to 0.33 mm wide, with 5 or 6 giant nuclei in the female. Longer lemniscus measures 2.15 to 3.47 mm long by 0.21 to 0.33 mm wide with 6, occasionally 7, giant nuclei in the male and measures 2.12 to 7.31 mm long by 0.19 to 0.62 mm wide with 6 giant nuclei in the female. The male reproductive system is located in the posterior third of trunk and consists of two oblong testes. There are eight clustered cement glands larger anteriorly, each with one large central giant nucleus and with independent cement ducts emptying at posterior end of Saefftigen’s pouch, along with prominent common sperm duct. The male gonopore is terminal. The female reproductive system is short and located in the broad and flat posterior end of trunk. The uterine bell contains many large nucleated cells with its dorsal and ventral anterior ends connected to body wall with filaments. The gonopore is sub-ventral occasionally covered by a looping posterior trunk expansion.[1]

The trunk is pseudosegmented, flattened laterally, has many prevalent sensory pits, and measures 3.0 to 74.0 mm long by 0.5 to 2.80 mm wide in the male and measures between 4.00 and 110.00 mm long by 0.60 and 4.00 mm wide in the much larger female. There are up to 100 annuli (structures that permits shortening and lengthening of the body by telescoping) in females but fewer in the shorter males. The proboscis is divided by a prominent ridge into two parts: anterior and posterior. The anterior proboscis is pear or apple-shaped with a truncated bare apical end measuring 250 to 339 long by 278 to 478 wide in the male and 300 to 438 long by 330 to 510 wide in the female.

The hooks posteriorly directed and measure between 35 and 76 long with the smallest found anteriorly and the longest in the middle. The posterior proboscis is conically shaped and measures 291 to 332 long by 591 to 689 wide at junction with anterior trunk in the male, and 323 to 365 long by 99 to 745 wide at junction with anterior trunk in the female.

The male reproductive system is located in the posterior third of trunk and consists of two oblong testes measuring Anterior testis measure 0.37 to 4.10 mm long by 0.30 to 1.10 mm wide and the posterior testis measure 0.32 to 3.15 mm wide. There are eight clustered cement glands larger anteriorly, each with one large central giant nucleus and with independent cement ducts emptying at posterior end of Saefftigen’s pouch, along with prominent common sperm duct. The male gonopore is terminal. The female reproductive system is short and located in the broad and flat posterior end of trunk. The uterine bell contains many large nucleated cells with its dorsal and ventral anterior ends connected to body wall with filaments. The gonopore is sub-ventral occasionally covered by a looping posterior trunk expansion. The eggs are ovoid being 65 to 86 long by 39 to 52 wide.[1] | ||
