Stenaelurillus albopunctatus Caporiacco, 1949: 474   , fig. 89a–b (D♂ ♀); lectotype ♂ and 2 ♂♂, 1 ♀ paralectotypes (designated here) in MSNF, examined.

Stenaelurillus albopunctatus   – Wesołowska 2014 b: 597, fig. 1A–F (♂ ♀).

Diagnosis

This species is most similar to S. kronestedti   from Tanzania ( Figs 317–329 View Figs 317–323 View Figs 324–329 ), with both species having very similar coloration and an almost identical conformation of the embolic division: viz., a hookshaped embolus with an anvil-shaped basis in the males. S. albopunctatus   can be readily distinguished from S. kronestedti   by the spatula-shaped RTA, the obtuse, wider and longer DTA, and the position of the row of long, transparent and black bristles on the DTA ( Fig. 41 View Figs 40–48 ) in the males, and by the closely situated copulatory openings (less than one diameter) and the markedly shorter insemination ducts in the females ( Figs 47–48 View Figs 40–48 ).

Material examined

Lectotype (designated here)

KENYA: ♂, Nairobi , 1°16′59″ S, 36°49′00″ E, 1944, Meneghetti leg.; according to Caporiacco (1949: 475), GoogleMaps   he also studied a single ♀ from the locality Elmenteita, ca 0°29′08.2″ S, 36°09′15.2″ E in Kenya, collected in December 1945 ( MSNF 645). GoogleMaps

Leg formula IV,III,I,II. Leg spination: I: Fm d 0-1-5; Pt pr 0-1-0; Tb pr 1-1, v 1-1 -2ap; Mt pr 1-1ap, v 2-2 ap. II: Fm d 0-1-2-4; Pt pr 0-1-0; Tb pr 1-1, v 1-1 -2ap; Mt pr 1-1ap, v 2-2 ap. III: Fm d 0-1-2-5; Pt pr and rt 0-1-0; Tb d 1-0-0, pr and rt 1-1-1-1, v 1 -0-2ap; Mt d 2-2, pr and rt 1-1-2ap, v 0-1- 2ap. IV: Fm d 0-1-1-5; Pt pr and rt 0-1-0; Tb d 1-0-0, pr and rt 1-1-1-1, v 1 -0-1ap; Mt d 2-0-0, pr and rt 1-1-2ap, v 1-1 -2-2ap. Coloration (in alcohol; Figs 45–46 View Figs 40–48 ). Carapace light red-brown, with dark brown eye field. Clypeus brownish yellow, sparsely covered with long white hairs. Sternum yellow, covered with long white hairs. Endites ( Fig. 13 View Figs 1–13 ), labium and chelicerae yellow. Abdomen: dorsum brown, with large, brown-shining scutum covering its anterior half; sides and venter bright yellow, with sparse brown speckles. Book-lung covers bright yellow. Spinnerets yellow, but the distal pair with dark brown tips. All legs orange yellow, except for darker legs I, with Tb ventrally and Mt and Tr entirely dark brown. Palps yellowish, cymbium dorsally covered with white hairs. Palpal structure as in Figs 40–44 View Figs 40–48 : VTA bulgeshaped; RTA spatula-shaped, directed anteriad; DTA massive and obtuse, bearing a row of thick bristles along its entire length, also with bristles situated in its proximal half that are transparent (whitish) and sometimes poorly visible, which is why they were not illustrated by some earlier authors (e.g., Wesołowska, 2014b: fig. 1B); the tegulum small and poorly seen; the functional tegulum wide and elongated, with well-developed proximal (PP) and distal (DP, as triangular concave plate) projections; the embolus relatively short and thick, with an anvil-shaped base.

Female (paralectotype)

The specimen is badly damaged, with the carapace and abdomen being detached from each other and with almost all legs and both palps being detached from the carapace. Measurements: carapace: 3.10 long, 2.30 wide, 1.65 high. Abdomen: 4.20 long, 3.20 wide. Ocular area: 1.28 long, 1.63 wide anteriorly, 1.63 wide posteriorly. Cheliceral length 0.68. Clypeal height 0.35. Diameter of AME 0.43. Length of leg segments: I 1.50 + 0.80 + 0.75 + 0.70 + 0.45 (4.20); II 1.53 + 0.75 + 0.83 + 0.75 + 0.55 (4.41); III 2.40 + 1.18 + 1.40 + 1.80 + 0.90 (7.68); IV 2.30 + 1.00 + 1.50 + 2.05 + 0.75 (7.60).

Yellow, tinged with brown, eye field dark brown. Clypeus yellowish, tinged with brown. Sternum, endites and labium bright yellow. Chelicerae yellow, anteriorly tinged with brown. Abdomen: dorsum yellow, densely covered with brown recumbent scales, with a poorly marked longitudinal yellow stripe; sides and venter bright yellow, with sparse brown speckles. Book-lung covers bright yellow. Spinnerets light brown, but the dorsal pair with dark brown tips. All legs yellow, but legs I and II visibly tinged with brown. Palps yellow. Epigyne and spermathecae as in Figs 47–48 View Figs 40–48 : epigynal plate flat, round, with a pair of ovoid copulatory openings situated rather close to each other (by less than their diameter); epigynal pocket absent; insemination ducts short, tube-shaped; primary spermathecae large, bean-shaped.
