DIAGNOSIS. — This species has a distinctive epigyne, with very large pocket and copulatory openings situated at posterior edge of epigyne. Tibia of female palp darker than other segments, contrasting.

ETYMOLOGY. — The species is named after its terra typica ( Sudan).

DISTRIBUTION. — Known only from the type locality.

Fig. 14. — Stenaelurillus zambiensis   n. sp., male (holotype) and female (paratype): A, palpal organ, ventral view; B, palpal organ, ventrolateral view; C, palpal organ,lateral view; D, E, palpal tibia; F, epigyne; G, internal structure of epigyne. Scale bars:A-E, 0.3 mm; F, G, 0.1 mm.




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. Thoracic part clothed in brown hairs, short rod bristles on anterior part of eye field.Anterior eyes surrounded by small fawn scales from above and white from below.Chelicerae light brown, unidentate, with very small retrolateral tooth.Labium and endites orange, sternum dark yellow.Clypeus low, brownish. Abdomen with striped pattern typical for Phlegra sp.   , three wide whitish bands on black background ( Fig. 16D View FIG ), dorsum covered with dense short hairs, their colouration according with blackground.Venter light, sides with dark marks.Ventral surface of body covered with dense light hairs. Spinnerets long, yellow with black tips. Legs orange, their hairs light, dense. Spines numerous, light. Palps yellow, but last segment brown, contrasting. Epigyne with single deep pocket, copulatory openings placed laterally, at posterior epigynal edge ( Fig.12B View FIG ).Internal structure as Fig.12C View FIG ,seminal ducts wide, spermathecae spherical.

Stenaelurillus uniguttatus Lessert, 1925   ( Fig. 13 View FIG )

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.



Cephalothorax:length 2.5, width 1.9, height1.0.Abdomen: length 2.6, width 1.7. Eye field: length 1.0, anterior width 1.6, posterior width 1.4.


Shape of body typical for the members of the genus. Specimen slightly bleached, carapace brownish with traces of lighter streaks on thoracic part, brown bristles on eye field. Mouth part light brown. Abdomen with characteristic pattern; generally velutinous black, but with broad transverse reflecting fillet in mid length of abdomen, single rounded light patch in anterior half. Venter light. Legs yellowish, their hairs and spines brown. Pedipalps as in Fig. 13 View FIG A-C; embolus with accompanying hooked structure and long, thin, pointed, membranous terminal apophysis ( Fig. 13D View FIG ). Retrolateral tibial apophysis small; retrolateral side of tibia ornamented with long, black, feather-shaped hairs; tuft of same hairs on tip of dorsal apophysis towards tibial base ( Fig. 13B, C View FIG ). Femur of palp with small bump ( Fig. 13E View FIG ).
