Etymology. The specific epithet is a noun in apposition referring to the Asela Zone in Oromia Region, Ethiopia, the area of origin of the new species.
Diagnosis. By the shape of the palpal tibia and the structure of the embolic division, the new species seems to be especially similar to both C. ruwenzoriensis Holm, 1962, from Uganda, and C. glabriceps Holm, 1962, from both Kenya and Uganda (Holm 1962). The male of C. asela n. sp. clearly differs from both above congeners by the shape of the carapace, the shapes of the apical projections of the palpal tibia and the presence of a distinct notch between them (marked with an arrow in Fig. 2D). From C. ruwenzoriensis, the new species differs also in the low distal apophysis of the convector being smaller, and from C. glabriceps by the wider embolus. The female is distinguished from C. ruwenzoriensis by the narrower epigynal plate, and from C. glabriceps by the rounded shape of the epigynal plate (vs subrectangular).
Description. Male (Paratype from Eth017). Total length 2.35. Carapace modified, as in Figs 1A–D, 1.10 long, 0.75 wide, greyish to greyish-yellow, with dark radial stripes. Head part of carapace with a rounded elevation holding the posterior median eyes; face of carapace with a group of bristles of different length. Eyes normal, not enlarged. Chelicerae 0.40 long, a mastidion absent. Legs greyish to greyish pale yellow. Leg I 2.91 long (0.85 + 0.28 + 0.65 + 0.63 + 0.50), IV 3.36 long (0.88 + 0.30 + 0.83 + 0.85 + 0.50). Chaetotaxy 2.2.1.1, spines about as long as 1–2 diameter of corresponding leg segment. Metatarsi I–IV with a trichobothrium each. TmI 0.60. Palp (Figs 2A–F): Tibia short, apically with a notch divided tibial distal part into two short parts: a prolateral part with a small apical claw, and retrolateral part with two apical claws. In addition, a small denticle situated at frontal surface of tibia (marked with an arrow in Figs. 2E and 2C). Paracymbium large, thick, unciform. Tegulum somewhat elongated, distally membraneous, slightly bent apically. Distal suprategular apophysis short, wide, with a small and narrow tooth at middle. Median membrane small, poorly visible. Embolus short, claw-shaped. Convector massive, its upper distal apophysis small, claw-shaped; low distal apophysis as a small tubercle. Opistosoma 1.20 long, 0.80 wide, dorsal pattern as in Fig. 1A.
Female (Paratype from Eth017). Total length 2.65. Carapace unmodified, as in Figs 1E, F, greyish to greyish-yellow, with dark radial stripes, 1.03 long, 0.75 wide. Chelicerae 0.43 long. Legs greyish to greyish-pale brown. Leg I 2.76 long (0.75 + 0.30 + 0.63 + 0.60 + 0.48), IV 3.15 long (0.82 + 0.30 + 0.78 + 0.80 + 0.45). Chaetotaxy and thrichobothriotaxy as in male TmI 0.59.

Distribution. Known only from the mountains of Oromia Region, Ethiopia, ranging from 3070 to 3770 m a.s.l.
