Etymology. The name is a noun in apposition, derived from the type locality.
Diagnosis. Distinguished from similar congeners ( lekoni group) by the combination of the following characters: male palpal trochanter-apophysis heavily sclerotized and ventrally serrated (similar to S. ndjole , S. kikongo ); epigynum with distinct anterior ridge ( Figs. 170 View FIGURES 163 – 183 , 267, 269 View FIGURES 267 – 270 ; similar to S. iboga , S. ndjole , S. kikongo ); male chelicerae without pair of large frontal apophyses ( Fig. 261 View FIGURES 259 – 266 ; in contrast to S. kikongo ); epigynum with short anterior projection ( Figs. 267, 269 View FIGURES 267 – 270 ; in contrast to S. kikongo ); procursus without serrated hairs at tip and without strong ventral spine ( Figs. 259–260 View FIGURES 259 – 266 ; in contrast to S. ndjole ).
Male (holotype). Total body length 4.5, carapace width 1.4. Leg 1: 46.7 (11.0 + 0.5 + 11.2 + 22.0 + 2.0), tibia 2: 7.1, tibia 3: 5.0, tibia 4: 7.1; tibia 1 L/d: 97. Distance PME-PME 125 µm, diameter PME 140 µm, distance PME- ALE 45 µm, distance AME-AME 45 µm, diameter AME 125 µm. Carapace ochre-yellow with brown triangular mark posteriorly and brown lateral margins; ocular area, clypeus and sternum brown; legs light brown, femora with two dark rings (medially, subdistally), tibiae with four dark rings (proximally, subdistally, and two in-between); abdomen ochre-gray with dark pattern dorsally, laterally, and ventrally, ventral dark bands with lateral constriction. Habitus as in Figs. 147–149 View FIGURES 143 – 152 , ocular area slightly elevated, secondary eyes with indistinct ‘pseudo-lenses’; clypeus with small and slightly hooked apophysis near rim ( Fig. 271 View FIGURES 271 – 280 ); deep thoracic pit and pair of shallow furrows diverging behind pit. Chelicerae as in Fig. 261 View FIGURES 259 – 266 , with lateral apophyses in very distal position, pair of rows of small frontal apophyses, without modified hairs. Palps as in Figs. 150–152 View FIGURES 143 – 152 ; coxa with indistinct retrolateral apophysis; trochanter with large, heavily sclerotized ventral apophysis serrated ventrally; femur with large retrolateral apophysis directed toward ventrally, proximal prolateral projection, and weakly sclerotized ventral projection distally; prolateral femur-patella joint strongly shifted toward ventrally; tarsus with some longer but barely stronger hairs dorsally; procursus as in Figs. 259–260 View FIGURES 259 – 266 , with complex membranous and sclerotized structures prolateroventrally ( Figs. 273, 276 View FIGURES 271 – 280 ), without hinge; bulb with simple process ( Figs. 262 View FIGURES 259 – 266 , 274 View FIGURES 271 – 280 ; 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 1.5%; prolateral trichobothrium present on all tibiae; pseudosegments barely visible. ALS with eight spigots each; gonopore with two epiandrous spigots ( Fig. 277 View FIGURES 271 – 280 ).
Variation. There is conspicuous variation among localities and the species may eventually turn out to include several reproductively isolated communities. Males from the Massif du Chaillu have slightly less complex sclerotized structures prolatero-ventrally on the procursus ( Figs. 265–266 View FIGURES 259 – 266 ) and frontally unmodified chelicerae; males from near Lastoursville south of the Ogooué River (Grotte de Pahon Pira and surrounding area) are very similar to those from the type locality (large ventral element on procursus darker and more pointed) while males from near Lastoursville north of the Ogooué River rather resemble those from the Massif du Chaillu ( Figs. 263–264 View FIGURES 259 – 266 ). Given the small sample of localities and specimens, these specimens are tentatively treated as one species pending further collecting and analysis. Tibia 1 in 12 other males (all localities combined): 8.5–11.5 (mean 9.9).
Female. In general similar to male; clypeus unmodified. Tibia 1 in 26 females: 6.5–8.8 (mean 7.5). Epigynum anterior plate with distinct anterior ridge ( Fig. 170, 180 View FIGURES 163 – 183 , 267 View FIGURES 267 – 270 ), with variably distinct shallow humps and depressions, females from Massif du Chaillu near Iboundji slightly different ( Figs. 181 View FIGURES 163 – 183 , 269 View FIGURES 267 – 270 ; females from between Yéno and Mouila again slightly different: pair of dark spots on epigynum smaller and wider apart; frontal pair of dark bands absent); posterior plate laterally with overhanging folds; internal genitalia as in Figs. 180, 181 View FIGURES 163 – 183 , 268, 270 View FIGURES 267 – 270 . Spinnerets as in male ( Figs. 278–279 View FIGURES 271 – 280 ).
Natural history. Litter-dwelling species. At Pahon Pira cave, this species was only found outside the cave.
Distribution. Known from several localities in southern Gabon ( Fig. 114 View FIGURE 114 ).
