Unknown.

Female

General appearance as in Fig. 16D View FIG . Carapace brown with darker eye field, two pairs of wide white streaks, first along lateral margins and second starting from anterior lateral eyes and extending to posterior edge of carapace.

Spinnerets long, yellow with black tips. Legs orange, their hairs light, dense. Spines numerous, light. Palps yellow, but last segment brown, contrasting.

Stenaelurillus uniguttatus Lessert, 1925: 478   , figs 64, 65.

MATERIAL EXAMINED. — Holotype. Kenya, Kibonoto , 3°11’S, 37°6’E, zone res. cultures, leg. Sjöstedt, 1 ♂ ( NR); one palp from the same specimen ( MHN). GoogleMaps  

DIAGNOSIS. — The male is easily distinguished from other members of the genus by abdominal pattern with transverse brilliant zone, except S. darwini   , from which differs in palp structure; long bristles on tibia stretch in S. darwini   to half of cymbium length, but they hang down in S. uniguttatus   .

DISTRIBUTION. — Known only from Kilimanjaro massif.
