Type. ♂ holotype from Gabon, Haut Ogooué  , forest at Lékoni  River (1 ° 10.7 ’S, 13 ° 32.3 ’E), 305 m a.s.l., 18.viii. 2011 (B.A. & S.R. Huber), in ZFMK (Ar 10203).

Other material examined. GABON: Haut Ogooué  : forest at Lékoni  River, same data as holotype, 2 ♂ 5 ♀ in ZFMK (Ar 10204); same data, 1 ♀ 3 juvs. in pure ethanol, in ZFMK (Gab 214).

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

Diagnosis. Easily distinguished from congeners by distinctive modification of clypeus (long median apophysis projecting downwards from rim; Fig. 246View FIGURES 246 – 252) and frontal apophyses on male chelicerae ( Fig. 250View FIGURES 246 – 252; similar S. mohoba  but much longer) and by triangular anterior epigynal plate with cone-shaped median process ( Figs. 168View FIGURES 163 – 183, 251View FIGURES 246 – 252).

Male (holotype). Total body length 3.7, carapace width 1.3. Leg 1: 42.4 (10.0 + 0.4 + 10.0 + 20.0 + 2.0), tibia 2: 6.2, tibia 3: 4.2, tibia 4: 6.4; tibia 1 L/d: 98. Distance PME-PME 135 µm, diameter PME 125 µm, distance PME- ALE 60 µm, distance AME-AME 45 µm, diameter AME 100 µm. Carapace ochre-yellow with brown triangular mark posteriorly and brown lateral margins; ocular area posteriorly brown, clypeus with brown pattern, sternum dark brown; legs light brown, femora with dark rings subdistally, tibiae with dark rings proximally and subdistally and additional indistinct ring medially; abdomen ochre-gray with dark pattern dorsally, laterally, and ventrally, ventral dark bands with lateral constriction. Habitus as in Figs. 138–139View FIGURES 133 – 142, ocular area slightly elevated, secondary eyes with indistinct ‘pseudo-lenses’; clypeus with long median apophysis projecting downwards from rim ( Fig. 246View FIGURES 246 – 252); deep thoracic pit and pair of shallow furrows diverging behind pit. Chelicerae as in Fig. 250View FIGURES 246 – 252, with lateral apophyses in very distal position, with distinctive, strongly ridged frontal apophyses, without modified hairs. Palps as in Figs. 140–142View FIGURES 133 – 142; coxa with retrolateral apophysis; trochanter with strong but simple ventral apophysis; femur with large retrolateral apophysis directed toward ventrally, proximally accompanied by two sclerotized humps, without prolateral modification, with weakly sclerotized slender ventral projection distally; prolateral femur-patella joint strongly shifted toward ventrally; tarsus with some longer and slightly stronger hairs dorsally; procursus as in Figs. 247–248View FIGURES 246 – 252, with complex membranous and sclerotized structures ventrally, without hinge; bulb with simple weakly sclerotized process ( Fig. 249View FIGURES 246 – 252; sperm duct apparently opens at basis of this process). 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: 8.5, 9.5.

Female. In general similar to male; clypeus unmodified. Tibia 1 in 5 females: 6.1–6.9 (mean 6.7). Epigynum anterior plate triangular with cone-shaped median process flanked by pair of shallow depressions ( Figs. 168View FIGURES 163 – 183, 251View FIGURES 246 – 252); posterior plate laterally with overhanging folds ( Fig. 251View FIGURES 246 – 252); internal genitalia as in Figs. 178View FIGURES 163 – 183 and 252View FIGURES 246 – 252.

Natural history. Litter-dwelling species that shares the microhabitat at type locality with a superficially similar Pholcus  species ( Pholcus  cf. moca Huber, 2011).

Distribution. Known from type locality only ( Fig. 114View FIGURE 114).
