Type locality. — N Thailand, Doi Suthep.
Type material. — Holotype ♂, pitfall trap, 1180 m, 28.vii.-29.viii.1986 ( MHNG) ; paratypes: as the holotype, 1 ♂ 1 ♀ ( MNHG), 28.vi-28.vii.1986, id .. 1 ♀ ( MHNG), 20.xii. 1985, id ., 3 ♂ 2 ♀ ( CD), 2.vii-2.viii.1987, id .. 1 ♀ ( CD), 2.i-1.iii.1987, id ., 1 ♀ ( CD), 2.i-1.iii.1987. id .. 1 ♂. 28.iv-30.v.1987, id- 1 ♂ 1 ♀, 2.viii-29.viii. 1987,id ., 1 ♀, 4.x- 5.xi.1987, id ., 1 ♂ 2 ♀, 29.viii-2.x. 1987, id ., 4 ♀, 28.vii.-29.viii.1986, P.

Diagnosis. — A long-legged species with uniform brown abdomen. The palpal tibial apophysis is deeply incised, with two claw-like branches. the embolus is inserted prodistally. Females are distinctive by round posterior spermathecae, separated by an almost triangular depression and lined laterally and posteriorly with a dark zone; the bursae are round. smaller and closer together. O. sima Simon (Thailand) , is allegedly distinct by the AME being much larger than ALE, by the dense pitting of the carapace. the male palpal tibia not longer than the patella and the small double teeth on the retrolateral tibial margin. Probably closely related to O. rugulosa but that species differs in the shape of the epigyne and the dark tips on the femora. O. ferox is larger. has much enlarged chelicerae and ringed legs. O. bucculenta Thorell has a differently shaped epigyne. O. andamanensis (Tikader) has large AM eyes and more widely separated spermathecae. 0. spadix sp. n. has a different palpal tibal apophysis.
Description. — MALE. Total length 4.50 mm. Carapace length 2.35 mm, width 1.55 mm. height 0.75 mm, head width 1.05 mm, eye group width 0.80 mm; abdomen length 2.15 mm. width 1.50 mm. Leg lengths: leg I 8.80 mm (2.25-2.90-2.40-1.25), leg II 6.65 mm (1.75-2.20-1.65-1.05). leg I11 5.80 mm (1.65-1.65-1.60-0.90), leg IV 8.10 mm (2.10-2.50- 2.40-1.10), palp 0.90-0.40-0.60- 0.95 mm. Carapace reddish brown, with feeble punctations. Mouthparts orange brown, legs uniform yellow, femur and tibia I slightly darker. Eyes as in scrobiculata , anterior median eyes not larger than other eyes. Clypeal hump feeble. rounded. Sternum almost smooth. Abdomen with dorsal scutum; ventrally a postgenital scutum reaching halfway spinnerets and a sclerotized ring around spinnerets. Leg spination: all femora with one short spine proximo-dorsally, femur I with one strong prolateral distal spine, anterior tibiae and metatarsi flattened ventrally; tibia I with 8 pairs of ventral spines, tibia II with 6 pairs, tibia III with 0-1 pv or 1- 1pv, tibia IV with 1-1pv, metatarsi I ventrally flattened with 6 pairs of ventral spines. metatarsus II with 4 pairs, metatarsus III with 0-1pv and sometimes 0-1rv, metatarsus 1V with 0-1pv. Male palp see diagnosis and figs 357, 358 View Figs 357-361 .
FEMALE ( fig. 359 View Figs 357-361 ). Total length 4.75 mm. Carapace length 2.50 mm, width 1.70 mm, height 0.75 mm. head width 1.20 mm, eye group width 0.90 mm, abdomen length 2.00 mm, width 1.60 mm, epigyne 0.45 mm wide. Leg lengths: leg I 8.70 mm (2.25-3.00-2.30 1.15). leg ll 6.75 mm (1.85-2.25-1.75-0.90), leg 111 5.70 mm (1.70-1.65-1.55-0.80), leg IV 7.85 mm (2.10-2.25- 2.40-1.10), palp 1.00-0.35-0.70- 0.90 mm. Colour as the male. legs all yellow. Abdominal dorsal scutum of variable length. ring around spinnerets absent. Spine formula as the male, but sometimes more spines on anterior legs, tibia 1I 1 with 0-lpv or 1-1pv and 0-1rv. Epigyne ( fig. 360 View Figs 357-361 ) and vulva ( fig. 361 View Figs 357-361 ) see diagnosis.
Variability. — Total length 4.50-5.50 mm; the two female specimens from Doi Inthanon have darker legs.
Distribution. — Only known from the mountains Doi Suthep and Doi Inthanon at altitudes of 1100-1600 m. In mixed population with 0. barbata .
