Euochin zunyi sp. nov. (AE义尧奇e)

Figs 162–176

Type material. Holotype: ♂ ( MHBU-ARA-00022217 ), CHINA: Guizhou Province, Zunyi City, Tongzi County, Chumi Town , Liangfengya Forest Park (ên垭f×ȓ园), 28.2576°N, 106.8469°E, 1405 m elev., 28 July 2019, leg. Z. Li.

Paratype: 1♀ ( MHBU-ARA-00022258 ), same data as holotype .

Etymology. The specific epithet is derived from the type locality: Zunyi City. Noun in apposition.

Diagnosis. Male palp closely resembles those of E. bamianshanensis , but can be recognized by: (1) the embolic opening facing upwards in ventral view; (2) the embolic disc being largely hidden by the tegulum. Female can be distinguished from E. bamianshanensis by the copulatory openings located close to the posterior margin of epigynal window (at anterior margin in E. bamianshanensis ).

Description. Male. Habitus shown in Figs162, 164 . Carapace length 1.517; abdomen length 1.430. Measurements of eyes: AME 0.350, ALE 0.244, PME 0.067, PLE 0.202. Measurements of legs: I 1.868 (0.581, 0.294, 0.400, 0.302, 0.291), II 1.624 (0.514, 0.227, 0.363, 0.269, 0.251), III 1.979 (0.657, 0.236, 0.425, 0.371, 0.290), IV 2.375 (0.761, 0.241, 0.502, 0.513, 0.358); leg formula: 4312. Color in ethanol: carapace dark brown, ocular area scattered with yellow setae. Abdomen dark brown, with light yellowish-white bands. Chelicera ( Fig. 166 ) with two promarginal and one retromarginal teeth. Palp ( Figs 167–168 , 171–174 ): distal femur, patella and tibia covered with long white setae; most part of embolic disc hidden beneath tegulum; embolus robust, nearly screw-like; CyF prominent; RTA robust.

Female. Habitus shown in Figs 163, 165 . Carapace length 1.485; abdomen length 1.490. Measurements of eyes: AME 0.339, ALE 0.237, PME 0.063, PLE 0.210. Measurements of legs: I 1.776 (0.553, 0.279, 0.380, 0.287, 0.277), II 1.553 (0.492, 0.217, 0.346, 0.257, 0.241), III 1.899 (0.625, 0.231, 0.410, 0.360, 0.273), IV 2.272 (0.728, 0.233, 0.479, 0.483, 0.349); leg formula: 4312. Color in ethanol: similar to that of male. Chelicerae as in male. Epigyne ( Figs 169–170 , 175–176 ): epigynal window small, circular; copulatory openings located postero-laterally on the rim of epigynal window; copulatory ducts relatively thick, with developed accessory glands; spermathecae globular.

Distribution. China (Guizhou).
