Type. ♂ holotype from Cameroon, Northwest Region, near Bamenda , under log at roadside (6°00.5’N, 10°18.1’E), 1750 m a.s.l., 16.iv.2009 (B.A. Huber), in ZFMK (Ar 10251).

Other material examined. CAMEROON: Northwest Region: near Bamenda , type above, together with 1♀; same data, 2♀ 2 juvs. in pure ethanol, in ZFMK (Cam 78). “Bali, Bafuchu Mbu, Shum Laka” [Mbu-Baforchu, ~ 5°50.4’N, 10°04.8’E], 1600 m a.s.l., pitfall, xii.1991 – ii.1992 (H. Doutrelepont), 2♂ 2♀ (4 vials) in MRAC (174768, 783, 860, 891).

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

Diagnosis. Easily distinguished from similar congeners (small species with male horns in ocular area) by unique modification of male clypeus ( Figs. 413 View FIGURES 411 – 415 , 432 View FIGURES 432 – 438 ), male chelicerae ( Fig. 436 View FIGURES 432 – 438 ; without modified hairs, with pair of strong frontal ridges), and by shapes of procursus and embolus ( Figs. 433–435 View FIGURES 432 – 438 ). Female difficult to distinguish from close relatives but internal anterior structure ( Figs. 414 View FIGURES 411 – 415 , 438 View FIGURES 432 – 438 ) narrower than in S. cornigera , S. nyasoso , and S. kala .

Male (holotype). Total body length 3.8, carapace width 1.3. Leg 1: 35.2 (8.2 + 0.5 + 8.4 + 16.6 + 1.5), tibia 2: 5.0, tibia 3: 3.5, tibia 4: 5.2; tibia 1 L/d: 79. Distance PME-PME 240 µm, diameter PME 135 µm, distance PME- ALE 115 µm, distance AME-AME 25 µm, diameter AME 95 µm. Carapace ochre-yellow with brown mark posteriorly, brown lateral margins and 2–3 submarginal spots on each side; ocular area not darkened, clypeus laterally with red-brown margins, sternum brown; legs ochre-yellow, with darker rings subdistally on femora and tibiae and proximally on tibiae; abdomen ochre-gray with dark pattern dorsally, laterally, and ventrally. Habitus as in Figs. 396–397 View FIGURES 391 – 400 , ocular area slightly elevated, each triad on additional hump, with one pair of long pointed horns above ALE ( Figs. 413 View FIGURES 411 – 415 , 432 View FIGURES 432 – 438 ), ‘pseudo-lenses’ not visible; clypeus with large complex process overhanging chelicerae ( Figs. 413 View FIGURES 411 – 415 , 432 View FIGURES 432 – 438 ); deep thoracic pit and pair of shallow furrows diverging behind pit. Chelicerae as in Fig. 436 View FIGURES 432 – 438 , with lateral proximal apophyses and pair of strong frontal ridges ending in short apophysis, without modified hairs. Palps as in Figs. 398–400 View FIGURES 391 – 400 ; coxa with retrolateral apophysis; trochanter with short rounded retrolatero-ventral apophysis; femur with weakly sclerotized retrolateral flap and large whitish area ventrally, without prolateral modification; prolateral femur-patella joint strongly shifted toward ventrally; tarsus with some barely longer and stronger hairs dorsally; procursus without hinge, with several brushes of feathered hairs retrolaterally, ventrally, and on prolateral side near basis; bulb with weakly sclerotized embolus ( Fig. 435 View FIGURES 432 – 438 ). 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.

Variation. Tibia 1 in 2 other males: 8.6, 9.0.

Female. In general similar to male; clypeus unmodified, with two dark bands from eye triads to rim; ocular area with one pair of low humps above ALE. Tibia 1 in 2 females: 7.1, 7.7. Epigynum anterior plate deeply indented posteriorly, with strongly protruding rim, anteriorly rugose ( Figs. 411–412 View FIGURES 411 – 415 , 437 View FIGURES 432 – 438 ); large flat posterior plate; internal genitalia as in Figs. 414 View FIGURES 411 – 415 and 438 View FIGURES 432 – 438 .

Distribution. Known from two localities in the Northwest Region of Cameroon ( Fig. 390 View FIGURE 390 ).
