The female of S. latibulbus is closest to that of S. kavango from Namibia (cf. Wesołowska, 2014b: fig. 5), but can easily be distinguished by the much shorter insemination ducts and the round, rather than bean-shaped, primary spermathecae ( Fig. 335 View Figs 330–335 ); yet, the copulatory openings are strongly sclerotized ( Fig. 334 View Figs 330–335 ) as compared to all the species of Stenaelurillus known to us. The male was described and diagnosed by Wesołowska (2014b: figs 6A–C), and seems to differ in the characteristic shape of the VTA, the distal projection of the functional tegulum and the conformation of the embolus, which unfortunately was shown by Wesołowska (2014b) too diagrammatically. See also remarks above under Diagnosis of S. fuscatus .

Carapace brown, eye field dark brown. Clypeus and cheeks dark brown, covered with dark brown hairs. Sternum yellow. Endites and labium dark yellow. Chelicerae brown. Abdomen: dorsum brown, with a pair of large dorso-lateral white spots on its rear half and a wide triangular white figure on its caudal part; venter yellow, with small dots of dark brown hairs forming two rows. Book-lung covers pale yellow. Spinnerets brown-yellow. All legs brown, covered with dark brown hairs. Epigyne and spermathecae as in Figs 334–335 View Figs 330–335 ; the epigynal plate flat, without visible structures; the copulatory openings look like a pair of black beans, widely separated; the insemination ducts wide and heavily sclerotized, forming C-shaped tubes running towards the median line; the primary spermathecae round.


Two localities in Congo and one in Zambia ( Fig. 513 View Fig ) ( Wesołowska 2014b; present data). This is the first record of this species since its original description.
