Figs 54 B–F, 55A–F, 56A–F, 57A–F, 58A–F, 59A–F 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 ).
