Material examined.

2 ♂ 3 ♀ (TRU - JS 0754–0758), China: • Xizang Autonomous Region, Medog County, Beibeng Township, Deergong Village, Yarlung Zangbo National Nature Reserve (29°10.84'N, 95°8.67'E, ca 1670 m), 25. V. 2024, X. Q. Mi et al. leg .

Diagnosis.

This species resembles O. tokaraensis in having very similar habitus and copulatory organs, especially the epigynal structure, but differs in: 1) embolus (E) originating at ca 4 o’clock position (Fig. 16 A, D) vs ca 6: 30 – ca 9: 00 o’clock position (Yang et al. 2024: figs 80–83); 2) membranous portions of copulatory ducts make 2 coils (Fig. 17 B) vs ~ 3 coils (Yang et al. 2024: figs 89, 91, 93, 99–101).

Re-description.

Male (Figs 16, 17 C, D, F, G). Total length 3.69. Carapace 1.79 long, 1.25 wide. Abdomen 2.01 long, 1.17 wide. Eye sizes and interdistances: AME 0.32, ALE 0.19, PLE 0.18, AERW 1.01, PERW 1.02, EFL 0.77. Legs: I 3.79 (1.13, 0.75, 1.00, 0.63, 0.28), II 2.53 (0.80, 0.48, 0.55, 0.40, 0.30), III 2.65 (0.80, 0.40, 0.55, 0.60, 0.30), IV 3.34 (1.00, 0.50, 0.83, 0.73, 0.28). Carapace dark, with marginal white setal band, covered with dense pale, golden and dark setae. Chelicerae mainly dark, with two promarginal teeth and one retromarginal tooth. legs I with thickness femora, patellae and tibiae, and single pro-ventral spine on tibiae. Dorsum of abdomen dark brown, with four pairs of transverse, pale stripes laterally; venter colored as dorsum.

Palp (Fig. 16 A – F): femur length / width ratio ca 2.44; patella almost as long as wide in retrolateral view; tibia ~ 1.6 × wider than long in ventral view, with strongly sclerotized retrolateral apophysis (RTA) bifurcated into sub-triangular ventral ramus and sub-semicircular dorsal ramus; cymbium ~ 1.54 × longer than wide; tegulum almost round, with prolatero-posterior bump (TB) and antero-retrolateral swollen portion; embolus (E) originating at ca 4 o’clock position, coiled in less than complete circle, with rather blunt tip.

Female (Fig. 17 A, B, E). Total length 4.40. Carapace 1.72 long, 1.14 wide. Abdomen 2.86 long, 1.64 wide. Eye sizes and interdistances: AME 0.34, ALE 0.17, PLE 0.15, AERW 0.91, PERW 1.01, EFL 0.71. Legs: I 2.79 (0.88, 0.63, 0.63, 0.40, 0.25), II 2.28 (0.65, 0.5, 0.5, 0.38, 0.25), III 2.55 (0.75, 0.45, 0.50, 0.55, 0.30), IV 3.52 (1.08, 0.58, 0.83, 0.73, 0.30). Habitus (Fig. 17 E) similar to that in male except paler and with thinner femora, patellae, and tibiae I.

Epigyne (Fig. 17 A, B) ~ 2 × wider than long, with pair of anteriorly located hoods (H) ~ 1.5 × longer than wide; atrium (At) almost oval; copulatory openings (CO) indistinct; copulatory ducts (CD) forming ~ 2 coils, with terminal bar-shaped accessory glands (AG) curved medially; spermathecae (S) tube-shaped, touching each other.

Distribution.

China (Xizang; Fig. 47), India (Tamil Nadu), Nepal (Kathmandu).

Comments.

Although the male specimens described here are almost identical to the holotype, they also have some differences, such as the origin of embolus, which arises at ca 4 o’clock position (vs ca 3 o’clock in the holotype; see Andreeva et al. 1984: fig. 49), those are here considered as interspecific variations.
