Diagnosis
Diagnosis. — A small uniform olive-grey species, with dark femora contrasting with light distal leg segments. The posterior eyes are equidistant. Males are identifiable by the shape of the retrolateral and the dorsal palpal tibial apophysis. In females, the arrangement of the dark elements in the epigyne is diagnostic; the openings are wide, situated anteriorly, thick-walled and crescent-shaped. Leg spine numbers on femora in females differ from that in males.

Carapace, chelicerae, femora, apical ring of tibiae and dorsal abdomen olive grey, head a little lighter, endites, coxae, sternum, dorsal side of tibia and metatarsi and tarsi and venter pale. Eyes: d AME=d ALE=d PLE= 11/2 d PME, PE equidistant, their diameter apart. Chelicerae with I tooth or 2 joint teeth on the retromargin and one frontal spine. Leg spination: all femora with 1 dorsal spine proximally, femur I with 3pl distally, tibia I with 7 pairs of ventral spines, tibia II 6 pairs, metatarsus I with 4 pairs, metatarsus II with 1-1-1-1 pl and 1-1-1rl, posterior legs spineless. Dorsal scutum over4/5 of abdomen, ventrally lacking scuta. Palp figs 652-653, femur with ventrally a large, broad triangular blunt apophysis (fig.654), tibia with a long and thin dorsal apophysis, retrolateral apophysis broad concave, with V-shaped excavation (fig. 653).

Discussion
Note.— Together with the specimens of O. onoi listed above, one similar-sized male of another, closely related species was found. This male is distinct by the pale coloured leg femora, in the palp the femoral apophysis is much reduced, the dorsal tibial apohysis is wider, shorter and curved and is fused at the base with the retrolateral apophysis, the latter is rectangular; the embolus is longer. The posterior eyes are equidistant.
