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).
Material examined
Holotype
TANZANIA: ♂, camp site at Lake Manyara, 3°36′48.9″ S, 35°53′09.0″ E, 2 Jan. 1972, T. Kronestedt leg. (NHRS 043).

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. Abdomen: dorsum dark brown, densely covered with brown recumbent scales, with three white spots on its rear half and large brown scutum on its front half; sides and venter bright yellow, with sparse brown speckles. Book-lung covers bright yellow. Spinnerets yellow, but the dorsal pair with dark brown tips. All legs yellow, tinged with brown, but legs I darker: Pt, Tb and Mt ventrally and Tr completely dark brown. Palps yellowish brown, dorsally covered with white hairs. Palpal structure as in Figs 317–321: VTA bulge-shaped; RTA hook-shaped, its ventral branch directed anteriad; DTA present as a thick, dorsally pointed process that bears a row of thick black bristles along its entire length; the cymbium without a cymbial lateral process; the tegulum is relatively small, without a tegular process; the functional tegulum wide and elongated, with well-developed proximal (PP) and wide, blade-shaped distal (DP) projections; the embolus relatively short and thick, with an anvil-shaped base.
