Material examined.

Holotype ♀, China, Jiangxi Prov., Ji’an City, Jinggangshan County Level City , Ciping Town , near Youth Quality Training Camp , 26°35'10.87"N, 114°09'42.52"E, 885 m, 27 Sep. 2018, Ke-ke Liu leg.

Etymology.

The name refers to the type locality, Ciping Town; adjective.

Diagnosis.

The female of this species is similar to that of O. gemata (Wang, 1994), the type species of the genus, in having the broad bugle-shaped copulatory ducts and touching sac-shaped posterior spermathecae, but differs by the longer copulatory duct with a spiral tube (vs. absent in O. gemata ) and the sac-shaped spermathecae with the anterior peanut-shaped parts slightly separated from each other (vs. Y-shaped parts touching in O. gemata ) (Fig. 6C, D ).

Description.

Female. Habitus as in Fig. 6A, B . Total length 7.71. Carapace 3.34 long, 2.40 wide. Eye sizes and interdistances: AME 0.14; ALE 0.21; PME 0.16; PLE 0.16; AME-AME 0.19; AME-ALE 0.10; PME-PME 0.19; ALE-ALE 0.61; PME-PLE 0.27; PLE-PLE 0.96; ALE-PLE 0.09; AME-PME 0.20; AME-PLE 0.29. MOA: 0.46 long; 0.44 anterior width, 0.48 posterior width. Chelicerae with a large basial tubercle, three promarginal teeth (median largest) and five retromarginal teeth (distal largest). Leg measurements: I 9.74 (2.61, 1.21, 2.48, 2.33, 1.11); II 9.09 (2.67, 0.95, 2.12, 2.15, 1.20); III 7.5 (2.07, 0.94, 1.49, 2.03, 0.97); IV 9.88 (2.5, 1.18, 2.38, 2.47, 1.35). Abdomen 3.78 long, 2.09 wide.

Coloration. Carapace yellow-brown, posteriorly with radial stripes. Chelicerae red-brown. Endites, labium, and sternum yellow-brown. Legs yellow-brown. Abdomen brown, dorsally with six pale chevron stripes on sub-medial part.

Epigyne (Fig. 6C, D ). Atrium broad, subfan-shaped, extending from anterior to posterior. Copulatory openings located at mediolateral part of the atrium. Copulatory ducts, anterior part bugle-shaped, posterior part connecting with a spiral tub, longer than spermathecae. Glandular tubes clustered, located at anterior part of spermathecae. Spermathecae in two pairs, anterior spermathecae peanut-shaped, slightly separated, sloping postero-laterally; posterior spermathecae sac-shaped, distal parts touching. Fertilization duct short, located medially on spermathecae.

Comments.

A cluster of blind tubes located on the anterior part of the spermathecae of this species is unclear to us; we called them glandular tubes. They are probably homologous with spermathecal heads also originated from spermathecae.

Distribution.

Known only from the type locality in Jiangxi Province, China (Fig. 8 ).
