Type. ♂ holotype from Gabon, Ogooué-Ivindo, Monts de Belinga , forest near Mayebout (1°06.7’N, 13°06.6’E), 500 m a.s.l., 13.–14.viii.2011 (B.A. & S.R. Huber), in ZFMK (Ar 10291).

Other material examined. GABON: Ogooué-Ivindo: Monts de Belinga , forest near Mayebout , same data as holotype, 2♂ 6♀ 1 juv. in ZFMK (Ar 10292); same data, 1 juv. in pure ethanol (identity uncertain, possibly S. ogooue ), in ZFMK (Gab 195).

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

Diagnosis. Distinguished from similar congeners (large species with long abdomen, cone-shaped modified hairs on male chelicerae, embolus with sclerotized proximal part) by combination of unmodified clypeus, shape of massive procursus (with ventro-distal apophysis; entire procursus similar S. simintang but more slender, Figs. 744– 745 View FIGURES 744 – 749 ), sclerotized proximal part of embolus with distinct prolateral projection ( Figs. 641 View FIGURES 638 – 647 , 747 View FIGURES 744 – 749 ), relatively large modified hairs on male chelicerae ( Fig. 746 View FIGURES 744 – 749 ; similar only in S. ebolowa ), and slightly angular anterior epigynal plate (in lateral view; Fig. 683 View FIGURES 678 – 693 ).

Male (holotype). Total body length 7.5, carapace width 2.0. Leg 1: 73.8 (17.3 + 0.8 + 16.9 + 35.5 + 3.3), tibia 2: 11.5, tibia 3: 7.9, tibia 4: 10.5; tibia 1 L/d: 87. Distance PME-PME 210 µm, diameter PME 195 µm, distance PME-ALE 90 µm, distance AME-AME 45 µm, diameter AME 175 µm. Carapace ochre-yellow with brown mark posteriorly and wide brown lateral margins; ocular area brown, clypeus lower half darkened, sternum dark brown; legs light brown, dark rings subdistally on femora and tibiae and in patella area, tips of femora and tibiae whitish; abdomen ochre-gray with distinct dark pattern dorsally, laterally, and ventrally. Habitus as in Figs. 638–639 View FIGURES 638 – 647 , ocular area slightly elevated, secondary eyes with distinct ‘pseudo-lenses’; clypeus unmodified except slightly longer hairs; deep thoracic pit and pair of shallow furrows diverging behind pit. Chelicerae as in Fig. 746 View FIGURES 744 – 749 , with lateral proximal apophyses and strong distal apophyses, the latter and frontal cheliceral face provided with large modified (cone-shaped) hairs. Palps as in Figs. 640–642 View FIGURES 638 – 647 ; coxa unmodified; trochanter with simple retrolatero-ventral apophysis; femur proximally with ventral pocket bordered retrolaterally by strong sclerotized ridge, with small retrolateral apophysis, without prolateral modification; prolateral femur-patella joint very prominent and strongly shifted toward ventrally (hidden by bulb in Fig. 640 View FIGURES 638 – 647 ); tarsus with some stronger hairs dorsally; procursus with distinct hinge between proximal and distal part, distally complex ( Figs. 744–745 View FIGURES 744 – 749 ); bulb with widened and heavily sclerotized proximal part of embolus with distinct prolateral projection ( Figs. 641 View FIGURES 638 – 647 , 747 View FIGURES 744 – 749 ). Legs without spines and curved hairs, with few vertical hairs, retrolateral trichobothrium on tibia 1 at 1%; prolateral trichobothrium present on all tibiae; pseudosegments barely visible.

Variation. Tibia 1 in two other males: 15.5, 16.5.

Female. In general similar to male. Tibia 1 in 5 females: 12.3–13.5 (mean 13.1). Epigynum large, consisting of wide, roughly triangular anterior plate slightly angular in lateral view and large posterior plate ( Figs. 682–683 View FIGURES 678 – 693 ); internal genitalia as in Figs. 696 View FIGURES 694 – 702 and 749 View FIGURES 744 – 749 .

Natural history. S. mayebout was found to share the forest at Mayebout with the superficially similar and widely distributed S. ogooue . While S. mayebout was rather found in hollow trees and cavities in the ground, S. ogooue was collected among tree buttresses.

Distribution. Known from type locality only ( Fig. 627 View FIGURE 627 ).
