Material examined.

China: holotype ♂, Jiangxi Province, Ji’an City, Jinggangshan County Level City , Jinggang Mountain National Nature Reserve , Ciping Town , Dajing village , 26.566°N, 114.125°E, 922 m, 13.VII.2014, K. Liu et al. leg.; 2 ♀, other data as in GoogleMaps holotype; 1 ♀, Longshi Town, Yuankou Village, 26°41'31.2"N, 113°57'10.8"E, 265 m, 1.V.2015, K. Liu et al. leg.; 1 ♀, Huang'ao Town , Shantang Group, 26°28'26.4"N, 114°13'58.8"E, 306 m, 5.IV.2015, K. Liu et al. leg GoogleMaps .


Female of this species similar to that of O. bhutanica Ono, 2001 and O. mucunica sp. nov. in having vulva with M-shaped pattern formed by copulatory ducts (CD) and spermathecae (SP), but differs from both species by the copulatory openings (CO) oriented outwards (vs. inwards or anteriorly) and copulatory ducts (CD) 2 × thinner than spermathecae (SP) (vs. equal in size) (cf. Fig. 8C, D View Figure 8 vs. Fig. 10C, D View Figure 10 and Ono 2001: figs 4, 5). Male of O. bicornis resembles those of O. bhutanica in having spine-like embolus (E) and moderately long retrolateral tibial apophysis (RTA), reaching to the middle of the cymbium but can be distinguished by the bifurcated retrolateral tibial apophysis (vs. horn-like) (cf. Fig. 9B-D View Figure 9 and Ono 2001: figs 2, 3).


Female. Habitus as in Fig. 8A, B View Figure 8 . Total length 5.77. Carapace: 2.09 long, 2.02 wide. Eye sizes and interdistances: AME 0.08, ALE 0.11, PME 0.08, PLE 0.1, AME-AME 0.22, AME-ALE 0.16, PME-PME 0.22, PME-PLE 0.38, AME-PME 0.29, AME-PLE 0.58, ALE-ALE 0.66, PLE-PLE 1.08, ALE-PLE 0.31. MOA 0.42 long, front width 0.36, back width 0.38. Endites more than 2 × longer than wide. Sternum as in Fig. 8B View Figure 8 with arch-shaped posterior end. Abdomen (Fig. 8A, B View Figure 8 ): 3.92 long, 1.11 wide, with regular transverse rows of strong spines on posterior part. Leg measurements: I 7.98 (2.45, 1.15, 2.15, 1.58, 0.65); II 7.79 (2.41, 1.10, 2.06, 1.50, 0.72); III 4.65 (1.39, 0.68, 1.27, 0.84, 0.47); IV 4.95 (1.76, 0.50, 1.25, 0.97, 0.47). Leg spination: I Fe: d4, p4, r1; Pa: d2, p1, r1; Ti: d2, p3, r3, v8; Mt: p2, r2, v6; II Fe: d4, p1, r1; Pa: d2, p1, r1; Ti: d3, p3, r3, v6; Mt: p2, r2, v6; III Fe: d2, p1; Pa: d2, p1; Ti: d1, p2, r1, v2; Met: p2, r2, v2; IV: Fe: d2; Pa: d2, p1, r1; Ti: d3, p2; Mt: p2.

Colouration. Carapace, chelicerae, endites, sternum, legs, and abdomen yellowish.

Epigyne (Fig. 8C, D View Figure 8 ). Epigyne 2 × wider than long. Copulatory openings (CO) hidden by lateral pockets (P). Spermathecae (SP) kidney-shaped, 2 × longer than wide. Copulatory ducts (CD) shorter than spermathecae, slightly curved, aggregative form V-shaped figure. Fertilisation ducts (FD) small, poorly visible and directed laterally.

Male (Fig. 9 View Figure 9 ): See Liu et al. (2017: 194).


Some females were collected in the type locality and others raised from juveniles. Newly collected females have general appearance and leg spination similar to the holotype male. Based on this, we consider them conspecific. This judgment will be confirmed or rejected in future when both sexes are collected together, simultaneously.


Known only from Jiangxi Province, China (Fig. 17 View Figure 17 ).
