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).
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).
