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 View FIGURES 131–137 ); also by shapes of procursus (distal elements; Figs. 131, 132 View FIGURES 131–137 ) and embolus (large sclerotized part with slender semitransparent projection; Figs. 133, 134 View FIGURES 131–137 ); 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 View FIGURES 115–130 ; pore plates much wider: Fig. 136 View FIGURES 131–137 ).

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 View FIGURES 115–130 . 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 View FIGURES 115–130 and 135 View FIGURES 131–137 , with one pair of lateral apophyses distally; each apophysis with one small modified hair at tip ( Figs. 160, 161 View FIGURES 155–168 ). Palps as in Figs. 119 and 120 View FIGURES 115–130 , coxa with indistinct bulge, trochanter barely modified, femur with retrolateral indentation but no distinct furrow, without proximal rim and without apophysis ( Fig. 155 View FIGURES 155–168 ), cymbium with long projection near tarsal organ, procursus with distinctive distal elements ( Figs. 131, 132 View FIGURES 131–137 , 155, 156 View FIGURES 155–168 ), bulb with complex embolus with two processes, one sclerotized, other mostly membranous ( Figs. 133, 134 View FIGURES 131–137 , 157, 158 View FIGURES 155–168 ). 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 View FIGURES 155–168 ); ALS with eight spigots each ( Fig. 162 View FIGURES 155–168 ).

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 View FIGURES 115–130 , 164 View FIGURES 155–168 ); internal genitalia as in Figs. 126 View FIGURES 115–130 and 136 View FIGURES 131–137 . ALS as in male ( Fig. 163 View FIGURES 155–168 ).

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