Etymology. The name is a noun in apposition, derived from the type locality.

Diagnosis. Easily distinguished from S. ankasa and other known congeners by distinctive shape of procursus ( Figs. 378–379 View FIGURES 378 – 383 ), male chelicerae (distal apophyses; Fig. 380 View FIGURES 378 – 383 ), and by epigynum with weakly protruding, deeply indented anterior plate ( Fig. 362 View FIGURES 359 – 371 , 383 View FIGURES 378 – 383 ).

Male (holotype). Total body length 3.4, carapace width 1.3. Leg 1: 33.7 (7.8 + 0.5 + 8.1 + 15.5 + 1.8), tibia 2: 4.9, tibia 3: 3.4, tibia 4: 5.2; tibia 1 L/d: 65. Distance PME-PME 170 µm, diameter PME 125 µm, distance PME- ALE 55 µm, distance AME-AME 35 µm, diameter AME 95 µm. Carapace ochre with darker median mark and lateral margins; ocular area ochre, clypeus with indistinct pair of dark bands, sternum dark brown; legs ochre, with dark rings on femora subdistally and tibiae proximally and subdistally; abdomen ochre with darker pattern dorsally, laterally, and ventrally. Habitus as in Figs. 354–355 View FIGURES 349 – 358 , ocular area slightly elevated, secondary eyes with very indistinct ‘pseudo-lenses’; clypeus unmodified; deep thoracic pit and pair of shallow furrows diverging behind pit. Chelicerae as in Fig. 380 View FIGURES 378 – 383 , with lateral proximal apophyses and distinctive distal apophyses, with large and small modified (cone-shaped) hairs. Palps as in Figs. 356–358 View FIGURES 349 – 358 ; coxa with rounded retrolateral hump; trochanter with simple ventral sclerotized hump; femur with whitish ventral area bordered retrolaterally by weakly sclerotized flap, without prolateral modification; prolateral femur-patella joint strongly shifted toward ventrally; tarsus with some barely stronger hairs dorsally; procursus with several distinctive sclerotized and membranous processes ( Figs. 378– 379 View FIGURES 378 – 383 ), distal part appears hinged (most clearly in dorsal view: Fig. 357 View FIGURES 349 – 358 ); bulb with weakly sclerotized conical embolus with subdistal branch ( Fig. 381 View FIGURES 378 – 383 ). Legs without spines and curved hairs, with few vertical hairs, retrolateral trichobothrium on tibia 1 at 2%; prolateral trichobothrium present on all tibiae; pseudosegments barely visible. Gonopore apparently with two epiandrous spigots (not confirmed by SEM).

Variation. Number and position of modified hairs on chelicerae slightly variable even within localities. Males from Kakum N.P. differ minimally in several respects: their palps are almost identical but the shape of the distal sclerotized procursus apophysis is slightly different; the distal cheliceral apophyses are slightly more slender; the legs are more slender and tend to be shorter. Tibia 1 in 11 males from Kakum N.P.: 6.4–8.4 (mean 7.6); in 8 males from all other localities: 7.8–9.4 (mean 8.9).

Female. In general similar to male. Tibia 1 in 18 females from Kakum N.P.: 5.0–6.8 (mean 5.8); in 18 females from all other localities: 5.8–9.0 (mean 7.2). Epigynum consisting of weakly protruding anterior plate with deep posterior indentation ( Figs. 362 View FIGURES 359 – 371 , 383 View FIGURES 378 – 383 ) and large posterior plate; internal genitalia as in Fig. 382 View FIGURES 378 – 383 .

Distribution. Known from several localities in southern Ghana ( Fig. 293 View FIGURE 293 ).
