Figs 442–447, 510
Diagnosis
By the body coloration, this species is very similar to another Sudanese species, S. sudanicus also described and known only from the holotype female (Figs 452–453), but can easily be distinguished from it by the position of the copulatory openings (widely separated, facing each other in S. siyamae sp. nov. and disposed to the epigastric furrow, facing backwards in S. sudanicus) and the longer, S-shaped insemination ducts (cf. Figs 443 and 453).
Etymology
This species is named after the collector of the holotype, Ms M. Siyam (South Sudan).
