Stenaelurillus kronestedti Próchniewicz & Heçiak, 1994: 39, figs 7a–k, 8a–e (D♂ ♀); ♂ holotype in NHRS, examined.

Diagnosis

This species is most similar to S. albopunctatus from Kenya (Figs 40–48), with both species having very similar coloration and an almost identical conformation of the embolic division in the males: viz., the hook-shaped embolus with an anvil-shaped basis. Stenaelurillus kronestedti can be readily distinguished from S. albopunctatus by the hook-shaped RTA, the pointed and narrower DTA and the position of the row of long and dense, black bristles on the DTA (Fig. 318) in the males and by the most widely separated copulatory openings (more than two diameters) and the markedly longer insemination ducts in the females (Fig. 323).

Carapace red-brown, densely covered with brown recumbent scales, with two wide longitudunal stripes of white scales and wide marginal.

white stripes of scales; eye field dark brown. Clypeus light brown, sparsely covered with white hairs. Sternum bright yellow, covered with long white hairs. Endites, labium and chelicerae bright yellow, tinged with brown.
