Material examined.

Holotype: ♀, China, Jiangxi Province, Ji’an City, Jinggangshan City, Jinggang Mountain National Nature Reserve , Mucun Town , Guibian Village , 26°38'32.11"N, 113°53'51.99"E, 322 m, 31.VII.2019, K. Liu et al. leg.

Etymology.

The specific name is derived from the type locality, Mucun Town.

Diagnosis.

Female of the new species is similar to those of O. bhutanica Ono, 2001 and O. bicornis in having vulva with M-shaped pattern formed by copulatory ducts (CD) and spermathecae (SP), but differ from both species by the copulatory openings oriented anteriorly (vs. outwards or inwards) (cf. Fig. 10C vs. Fig. 9C and Ono 2001: fig. 4). Additionally, O. mucunica sp. nov. differs from O. bicornis by the copulatory ducts being as wide as spermathecae (vs. copulatory ducts 2 × thinner) (cf. Fig. 10D and Fig. 8D ).

Description.

Habitus as in Fig. 10A, B . Total length 11.74. Carapace: 3.67 long, 3.33 wide. Eye sizes and interdistances: AME 0.08, ALE 0.14, PME 0.09, PLE 0.11, AME-AME 0.14, AME-ALE 0.07, PME-PME 0.08, PME-PLE 0.20, AME-PME 0.14, AME-PLE 0.39, ALE-ALE 0.39 PLE-PLE 0.77, ALE-PLE 0.05. MOA 0.52 long, front width 0.38, back width 0.43. Endites more than 2 × longer than wide, sub-trapezoidal. Abdomen (Fig. 10A, B ): 8.42 long, 2.68 wide, with abundant white guanine spots dorsally and regular transverse rows of strong spines on posterior part. Leg measurements: I 8.56 (2.69, 0.99, 2.36, 1.65, 0.87); II 8.06 (2.50, 0.97, 2.24, 1.62, 0.73); III 4.77 (1.41, 0.60, 1.34, 0.90, 0.52); IV 4.88 (1.75, 0.54, 1.20, 0.93, 0.46). 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: d3, r2, v2; Mt: p2, r2, v2; IV: Fe: d2; Pa: d2, p1, r1; Ti: d2, p2; Mt: p2.

Colouration (Fig. 10A, B ). Carapace, chelicerae, endites, sternum, legs, and abdomen yellowish.

Epigyne (Fig. 10C, D ). Epigyne 1.5 × wider than long. Pockets absent. Copulatory openings (CO) large, as long as wide, with weakly sclerotised margins. Spermathecae (SP) cylindrical, smoothly merging into copulatory ducts. Copulatory ducts (CD) very wide, touching each other almost the entire length. Fertilisation ducts (FD) short, directed laterally.

Male. Unknown.

Notes.

While many juveniles were collected and reared in the lab, only one female reached maturity.

Comments.

The new species could potentially be a synonym of one of the species known only from males and occurring in China: O. clavulata Tang, Yin & Peng, 2008 (Yunnan) or O. placentiformis Wang, Chen & Zhang, 2012 (Guangxi).

Distribution.

Known only from the type locality in Jiangxi Province of China (Fig. 17 ).
