Type. ♂ holotype from Gabon, Ogooué-Ivindo, Ivindo N.P. near Simintang (0°32.2’N, 12°41.3’E), 545 m a.s.l., forest, 16.viii.2011 (B.A. & S.R. Huber), in ZFMK (Ar 10293).

Other material examined. GABON: Ogooué-Ivindo: Ivindo N.P. near Simintang , same data as holotype, 1♂ 4♀ in ZFMK (Ar 10294); same data, 4 juvs. in pure ethanol, in ZFMK (Gab 217).

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 shape of massive procursus (with ventrodistal apophysis; entire procursus similar S. mayebout but wider and shorter, Figs. 750–751 View FIGURES 750 – 755 ), sclerotized proximal part of embolus with distinctive retrolatero-ventral projection ( Fig. 645 View FIGURES 638 – 647 ), modified hairs on male chelicerae ( Fig. 752 View FIGURES 750 – 755 ; smaller than in S. mayebout and S. ebolowa ), and strongly protruding anterior epigynal plate (in lateral view; Fig. 685 View FIGURES 678 – 693 ). From most congeners (except S. ebolowa , S. kribi , S. bwiti ) also by modified male clypeus (slightly projecting rim set with small modified, cone-shaped hairs).

Male (holotype). Total body length 7.0, carapace width 1.9. Leg 1: 73.7 (17.3 + 0.8 + 16.7 + 35.6 + 3.3), tibia 2: 11.2, tibia 3: 7.7, tibia 4: 10.4; tibia 1 L/d: 94. Distance PME-PME 185 µm, diameter PME 195 µm, distance PME-ALE 105 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 posteriorly, clypeus lower half darkened, sternum dark brown with some light spots; 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. 643–644 View FIGURES 638 – 647 , ocular area slightly elevated, secondary eyes with distinct ‘pseudo-lenses’; clypeus with about six small modified (cone-shaped) hairs near rim; deep thoracic pit and pair of shallow furrows diverging behind pit. Chelicerae as in Fig. 752 View FIGURES 750 – 755 , with lateral proximal apophyses and strong distal apophyses, the latter and frontal cheliceral face provided with modified (cone-shaped) hairs. Palps as in Figs. 645–647 View FIGURES 638 – 647 ; coxa unmodified; trochanter with simple retrolatero-ventral apophysis; femur proximally with ventral pocket bordered retrolaterally by strong sclerotized ridge, with tiny retrolateral apophysis, without prolateral modification; prolateral femurpatella joint very prominent and strongly shifted toward ventrally (hidden by bulb in Fig. 645 View FIGURES 638 – 647 ); tarsus with some stronger hairs dorsally; procursus with distinct hinge between proximal and distal part and ventro-distal apophysis ( Figs. 750–751 View FIGURES 750 – 755 ); bulb with widened and sclerotized proximal part of embolus with heavily serrated dorsal ridge and distinct ventral projection ( Figs. 645–647 View FIGURES 638 – 647 , 753 View FIGURES 750 – 755 ). 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.

Variation. Tibia 1 in other male: 14.5.

Female. In general similar to male but clypeus unmodified. Tibia 1 in 4 females: 12.7, 12.7, 13.1, 14.0. Epigynum large, consisting of wide, roughly triangular anterior plate clearly protruding in lateral view and large posterior plate ( Figs. 684–685 View FIGURES 678 – 693 , 754 View FIGURES 750 – 755 ); internal genitalia as in Figs. 697 View FIGURES 694 – 702 and 755 View FIGURES 750 – 755 .

Natural history. S. simintang adult specimens build large webs in large protected spaces near the ground. Such spaces are rare at the type locality, explaining the low number of specimens despite of considerable collecting effort.

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