sp. nov.

Stenaelurillus bandama View in CoL sp. nov. Figs 63–78 View Figs 63–72 View Figs 73–78 , 510

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


The males of the new species are most similar to those of S. hirsutus ( Figs 239–242 View Figs 239–245 , 246–251 View Figs 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 View Figs 73–78 , 253, 255 View Figs 252–257 ). The females of S. bandama sp. nov. are most similar to those of S. iubatus ( Figs 278–279 View Figs 274–279 ), 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 .


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