Figs. 3–4, 115–116, 119–120, 123–126, 131–136, 155–164

Type. Male holotype from Kenya, Eastern Province , Mt. Kenya N.P., Chogoria Forest, ‘site 1’ (0°12.1’S, 37°29.4’E), 2460 m a.s.l., 27.i.2010 (B.A. Huber), in ZFMK (Ar 8495) GoogleMaps   .

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

Diagnosis. Easily distinguished from most known congeners by long process near male palpal tarsal organ ( Figs. 131, 132); also by shapes of procursus (distal elements; Figs. 131, 132) and embolus (large sclerotized part with slender semitransparent projection; Figs. 133, 134); from very similar S. bujongolo   only by minor details of procursus tip (membranous part whitish rather than transparent; distal apophysis slightly longer), semitransparent embolar process (straight rather than curved), and female genitalia (longer anterior epigynal plate; border of anterior plate without whitish area separating pair of black structures at rim: Fig. 124; pore plates much wider: Fig. 136).

Male (holotype). Total body length 7.9, carapace width 2.8. Leg 1: 64.1 (16.5 + 1.2 + 16.5 + 26.3 + 3.6), tibia 2: 12.3, tibia 3: 9.7, tibia 4: 12.8; tibia 1 L/d: 53. Habitus as in Figs. 115 and 116. Carapace with wide median and lateral brown bands, clypeus with pair of wide brown bands, sternum dark brown, legs ochre-brown, femora and tibiae with darker subdistal rings, abdomen with distinct pattern dorsally and ventrally. Distance PME-PME 185 µm, diameter PME 230 µm, distance PME-ALE 175 µm, distance AME-AME 70 µm, diameter AME 160 µm. Ocular area slightly elevated, secondary eyes with small ‘pseudo-lenses’; deep thoracic pit. Chelicerae as in Figs. 123 and 135, with one pair of lateral apophyses distally; each apophysis with one small modified hair at tip ( Figs. 160, 161). Palps as in Figs. 119 and 120, coxa with indistinct bulge, trochanter barely modified, femur with retrolateral indentation but no distinct furrow, without proximal rim and without apophysis ( Fig. 155), cymbium with long projection near tarsal organ, procursus with distinctive distal elements ( Figs. 131, 132, 155, 156), bulb with complex embolus with two processes, one sclerotized, other mostly membranous ( Figs. 133, 134, 157, 158). Legs without spines, few vertical hairs, with curved hairs ventrally and dorsally on all tibiae and metatarsi, also on femora 1 and 2, retrolateral trichobothrium on tibia 1 at 2%; prolateral trichobothrium present on tibia 1. Gonopore with two epiandrous spigots ( Fig. 159); ALS with eight spigots each ( Fig. 162).

Variation. Tibia 1 in 17 other males: 14.0–18.5 (mean 16.3).

Female. In general similar to male; tibia 1 in 29 females: 11.6–17.3 (mean 14.5). Epigynum anterior plate roughly triangular, without pockets; arc-shaped posterior plate ( Figs. 124, 125, 164); internal genitalia as in Figs. 126 and 136. ALS as in male ( Fig. 163).

Distribution. Widely distributed at higher elevations (mostly between 2000 and 3000 m a.s.l.) in central and western Kenya ( Fig. 58).
