Stenaelurillus glaber Wesołowska & Russell-Smith, 2011: 593   , figs 151, 152, 238-240.

MATERIAL EXAMINED. — Ghana, Aburi , 5°51’N, 0°11’W, 26.I.1991, leg. W. Puławski, 1 ♂ ( CAS) GoogleMaps   ; Uganda, [without precise locality], VIII-IX.1913, leg. K. Kittenberger, 1 ♂ ( MTM)   ; Pakwach , 2°28’N, 31°30’E, sweep net, 7.IV.1995, leg. D. Penney, 1 ♂ ( MNH) GoogleMaps   .

DISTRIBUTION. — Hitherto known from Nigeria, recorded for the first time in Ghana and Uganda here.

REMARKS. — Species very similar to S. hirsutus Lessert, 1927   , but differs in having low, light clypeus (high, black with light vertical stripes in S. hirsutus   ) and light coloration of palp.

DIAGNOSIS. — The male is easily distinguished by characteristic striped pattern of clypeus (white with two vertical black stripes) and presence of protrudent “mane” on eye field. The female has epigyne with fissured horizontal copulatory openings (see fig. 267 in Wesołowska & Russell-Smith 2000).

DISTRIBUTION. — Species hitherto known from Ghana, Congo and Tanzania, for the first time recorded in Central Africa, Ivory Coast and Senegal.

COMMENTS. — The type of S. hirsutus   is slightly bleached, its carapace bald, the majority of hairs rubbed of, only thick rod hairs on anterior half of eye field preserved. Also clypeus is devoid of hairs, uniformly light. Still in original description author reports the presence of two vertical black stripes on cylpeus and long bristles on eye field ( Lessert 1927: fig. 18b). During my studies on Stenaelurillus   , I met many times specimens which lost part/majority of their ornamental hairs. Analysis of coloration, palpal structure and distribution of S. cristatus   and S. hirsutus   justified synonymization of their names, so I propose S. cristatus   as a junior synonym of S. hirsutus   .

Measurements

Cephalothorax: length 2.3-2.7, width 1.5-1.9, height 1.0-1.1. Abdomen:length 2.4-2.5, width1.8- 2.3. Eye field:length 0.9-1.1, anterior and posterior width 1.5-1.7.

Male

General appearance as in Figure 15A, B View FIG . Carapace oval, slightly broader posteriorly, moderately high, with short eye field.Colouration of carapace brown, white hairs form two parallel stripes on thoracic part, lateral edges of carapace also lighter.
