Diagnosis

Differs from all other Eviulisoma   species, except E. articulatum   sp. nov. and E. lanceolatum   , by the obviously articulated gonopod acropodite. Very similar to E. articulatum   sp. nov., with which it shares the very large, subrectangular solenophore, but differs from that species by having a cylindrical mesal acropodite process (map) without a subapical side branch (vs map tapering, with a side branch), as well as by having a triangular hypoproct (vs a rounded trapezoid, tritubercuate hypoproct).

Material studied

Syntypes

TANZANIA (all in ZSM): 1 ♂ (only posterior half), 1 ♀, in alcohol, non-original label “ Himatiopus iuloideus Verhoeff, Tanganjika, Tier   mit Originaldet.-Etik. (Typus-Verd.), ehem. Trockenm. Etik. Nr. 1277 ”;   slide with gonopod, labelled “ A20035148 , Himatiopus juloideus Verh. Gp. ♂ Tanganjika   ”;   slide with male leg pairs 1–6, labelled “ A20035147 , Himatiopus juloideus Verh.   1.–6. B. ♂ Tanganjika ”;   2 ♀♀, in alcohol, “ Tanganykia, Mufindi, Iringa, in tea nursery, xii – 1930, W. V. Harris, from DAO ”.  

Remarks

As far as can be seen from the available material, E. iuloideum   shares the general morphology of the Udzungwan Eviulisoma   species. It is especially similar to E. articulatum   sp. nov., from which it differs gonopod-wise as specified in the diagnosis. Figure 32 View Fig. 32 (from Verhoeff 1941) shows the gonopod telopodite of E. iuloideum   ; a restudy of the gonopod slide confirmed that Verhoeff’s drawing is accurate.In particular, the mesal acropodital process (map) does not have a subapical side branch. The two species also differ in the shape of the hypoproct, which in E. iuloideum   is triangular vs rounded trapezoid, with three tubercles in E. articulatum   sp. nov. According to Verhoeff (1941), E. iuloideum   , unlike E. articulatum   sp. nov., has no setae on the collum and body rings (“spärliche Beborstung nur am Telson”), but considering how delicate and hard to see these setae are, this difference is hardly significant. The type locality of E. iuloideum   , “Tanganjikasee bei Mufundi-Iringa”, probably refers to Mufindi SW of Iringa City, some 100 km SW of the type locality of E. articulatum   sp. nov., i.e., outside the Udzungwa Mts (and, as is the case with several other localities at the “Tanganjikasee” mentioned by Verhoeff 1941, very far from Lake Tanganjika [did Verhoeff misread “tea nursery”?]).
