Etymology. The name is a noun in apposition, derived from the type locality.
Diagnosis. Easily distinguished from most known congeners by modified male clypeus (slightly projecting rim set with modified (cone-shaped) hairs: Figs. 725, 731 View FIGURES 725 – 737 ); from species with similar clypeus ( S. simintang , S. kribi , S. bwiti ) by shape of procursus (massive, with short distal apophysis, without ventral branch, Figs. 716–717 View FIGURES 716 – 724 ); also by relatively large modified hairs on male chelicerae ( Fig. 722 View FIGURES 716 – 724 ; similar only in S. mayebout ), and parallel ventral ridges on procursus prolaterally (visible only after detachment of bulb; Fig. 716 View FIGURES 716 – 724 ). Female not easily distinguished from similar species with roughly triangular anterior epigynal plate evenly curved in lateral view (especially S. belinga ).
Male (holotype). Total body length 6.8, carapace width 1.7. Leg 1: 78.0 (17.6 + 0.7 + 17.7 + 38.7 + 3.3), tibia 2: 12.1, tibia 3: 8.4, tibia 4: 10.9; tibia 1 L/d: 100. Distance PME-PME 170 µm, diameter PME 170 µm, distance PME-ALE 90 µm, distance AME-AME 35 µm, diameter AME 160 µm. Carapace ochre-yellow with brown mark posteriorly and brown lateral margins; ocular area brown posteriorly, clypeus with pair of dark marks in lower half, sternum dark brown; legs ochre-yellow, dark rings subdistally on femora and tibiae and in patella area, tips of femora and tibiae whitish; abdomen ochre-gray with distinct black pattern dorsally, laterally, and ventrally. Habitus as in Figs. 628–629 View FIGURES 628 – 637 , ocular area slightly elevated, secondary eyes with distinct ‘pseudo-lenses’; clypeus slightly projecting, with about 12 modified (cone-shaped) hairs near rim ( Figs. 725, 731 View FIGURES 725 – 737 ); deep thoracic pit and pair of shallow furrows diverging behind pit ( Fig. 726 View FIGURES 725 – 737 ). Chelicerae as in Figs. 722 View FIGURES 716 – 724 and 732 View FIGURES 725 – 737 , with lateral proximal apophyses and large distal apophyses, the latter and frontal cheliceral face provided with very large modified (cone-shaped) hairs ( Figs. 733–735 View FIGURES 725 – 737 ). Palps as in Figs. 630–632 View FIGURES 628 – 637 ; coxa unmodified; trochanter with simple retrolatero-ventral apophysis; femur proximally with ventral pocket bordered retrolaterally by strong sclerotized ridge ( Fig. 727 View FIGURES 725 – 737 ), with small retrolateral apophysis, without prolateral projection; prolateral femur-patella joint very prominent and strongly shifted toward ventrally (hidden by bulb in Fig. 630 View FIGURES 628 – 637 ); tarsus with some stronger hairs dorsally ( Fig. 730 View FIGURES 725 – 737 ); procursus with distinct hinge between proximal and distal part, with distinctive ridges prolaterally (visible only after detachment of bulb; Fig. 716 View FIGURES 716 – 724 ); bulb with heavily sclerotized proximal part of embolus ( Figs. 718 View FIGURES 716 – 724 , 728 View FIGURES 725 – 737 ). 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. Gonopore with two epiandrous spigots ( Fig. 736 View FIGURES 725 – 737 ).
Variation. Males from South Region all very similar to holotype, but with slight variation in number of modified hairs on male chelicerae and clypeus (up to about 20) and in size and distinctiveness of ridges and teeth on sclerotized proximal part of embolus. Males from Centre Region and Littoral Region show additional slight differences and are therefore assigned tentatively: shapes of ventro-distal apophyses on procursus slightly different (retrolateral apophysis shorter and less pointed; prolateral apophysis longer); dorso-distal sclerotized part of procursus either stronger (Yaoundé area) or less developed (Koukoué); prolateral ridges of procursus fewer but stronger in males from Yaoundé area; modified hairs near median line of male chelicerae more widely spaced in males from Yaoundé area; entire procursus either slightly more slender (Koukoué) or shorter (“Ercalera”); cheliceral apophyses more slender in males from Yaoundé area. Even more pronounced variation occurs in sclerotized proximal part of embolus ( Figs. 719–721 View FIGURES 716 – 724 ). Tibia 1 in 15 other males (all localities combined): 13.9– 18.3 (mean 16.4).
Female. In general similar to male but clypeus unmodified; clypeus variably dark; posterior median light line ventrally on abdomen absent. Tibia 1 in 22 females: 10.8–14.0 (mean 12.9). Epigynum large, consisting of evenly curved (in lateral view), roughly triangular anterior plate and large posterior plate ( Figs. 678–679 View FIGURES 678 – 693 , 723 View FIGURES 716 – 724 , 737 View FIGURES 725 – 737 ); internal genitalia as in Figs. 694 View FIGURES 694 – 702 and 724 View FIGURES 716 – 724 .
Natural history. S. ebolowa was found in well preserved forests (e.g. in a small canyon near Ebolowa ) and in disturbed forest patches (e.g. in man-made holes in the ground in disturbed forest fragments near Koukoué and Nkoetye). The large webs were built in sheltered spaces near the ground.
Distribution. Known from several localities in southwestern Cameroon ( Fig. 627 View FIGURE 627 ).
