Spermophora Ken  21: Dimitrov, Astrin & Huber 2012 ( DNA sequence data).


Easily distinguished from similar congeners ( S. berlandi Fage, 1936  , S. minotaura Berland, 1920  ) by absence of horns between eye triads; from S. berlandi Fage, 1936  also by absence of epigynal scape (only short conical projection; Fig. 105View Figs 102 - 106), from S. minotaura Berland, 1920  also by unmodified clypeus; from both and from other species also by details of male palp morphology (shapes of bulbal processes and procursus; Figs 102, 103View Figs 102 - 106) and male cheliceral armature ( Fig. 104View Figs 102 - 106).


Kirinyaga  is a Kikuyu and Embu name for Mount Kenya; noun in apposition.

Male (holotype)

MEASUREMENTS. Total body length 2.2, carapace width 1.1. Leg 1: 17.1 (4.2 + 0.4 + 4.3 + 6.2 + 2.0), tibia 2: 2.6, tibia 3: 2.0, tibia 4: 2.6; tibia 1 L/d: 46. Distance PME-PME 205 µm, diameter PME 90 µm, distance PME-ALE 25 µm, no AME.

COLOR. Prosoma ochre with extensive black pattern including ocular area and clypeus, sternum mostly black, medially dark brown, legs ochre-yellow, darker subdistal rings and lighter tips barely visible, abdomen ochre-grey, largely covered with black marks, also ventrally.

BODY. Habitus as in Fig. 50; ocular area slightly elevated, without horns; shallow but distinct thoracic furrow; clypeus unmodified. Chelicerae as in Fig. 104View Figs 102 - 106, with proximal lateral apophyses, large frontal apophyses (without modified hairs) and three long modified hairs on each side, the distal one accompanied by small black cone. Sternum wider than long (0.72/0.64), unmodified.

PALPS. As in Figs 102 and 103View Figs 102 - 106, coxa with retrolatero-ventral apophysis, trochanter with retrolateral apophysis, femur barely modified, procursus with ventral flap and several complex distal elements that appear hinged with proximal part, bulb with only one distally bifid process and small rounded projection on opposite side.

LEGS. Without spines and curved hairs, few vertical hairs; retrolateral trichobothrium on tibia 1 at 14%; prolateral trichobothrium absent on tibia 1, present on other tibiae; tarsus 1 with ~20 pseudosegments.

VARIATION. Tibia 1 in 5 other males: 3.9-4.0.


In general similar to male but triads closer together (distance PME-PME 135 µm). Tibia 1 in 2 females: 3.4, 3.5. Epigynum a large protruding plate with small projection posteriorly ( Fig. 105View Figs 102 - 106); internal genitalia as in Fig. 106View Figs 102 - 106.


Known from type locality only ( Fig. 27View Figs 24 - 27).
