Type material. Male holotype from Nigeria, Ibadan [7°23’47”N 3°55’E], 1 April 1973, A. Russell-Smith leg., deposited in MRAC 245546. Paratypes from the same vial as holotype: 13 males and 3 females .
Etymology. The specific name refers to the type locality, adjective.
Diagnosis. Males of Yoruba ibadanus sp. nov. are distinguished from those of Y. toubensis sp. nov. by the presence of a screw-shaped embolus (laminar and without folds in Y. toubensis sp. nov.) and straight VTA (pointing retrolaterally in ventral view in Y. toubensis sp. nov.) (Figs 58D, 59B, C); females differ of Y. toubensis sp. nov. by the presence of an epigynal scape (absent in Y. toubensis sp. nov.) and the slender connecting ducts, with proximal part curving behind the copulatory duct (Fig. 59E).
