Stenaelurillus hirsutus – Wesołowska 2014 b: 603–604; in part, the specimens from Côte d’Ivoire only.

Diagnosis

The males of the new species are most similar to those of S. hirsutus ( Figs 239–242 , 246–251 ), from which they can easily be distinguished by the narrower, nail-shaped embolus (ribbon-shaped in S. hirsutus ) and the wider vertical white stripes on the clypeus (cf. Figs 74, 76 , 253, 255 ). The females of S. bandama sp. nov. are most similar to those of S. iubatus ( Figs 278–279 ), but can be distinguished from them by the longer epigynal pocket and the shorter insemination ducts. See also remarks below under Diagnosis of S. striolatus .

Etymology

The specific epithet refers to the Bandama River, the longest river in Côte d’Ivoire, on which the type locality is situated.
