(屏±尧奇e) Figs 78–93 Type material. Holotype : ♂ ( MHBU-ARA-00022224 ), CHINA : Yunnan Province , Pingbian County , Daweishan National Park , 22.9057°N , 103.6980°E , 2101 m elev., 8 August 2019 , leg. Y. Mu , Y. Chen , L. Zhao . FIGURES 78–86. Euochin pingbian sp. nov. , holotype male (78, 80, 82, 83–84) and paratype female (79, 81, 85–86). 78–79. Habitus, in dorsal view; 80–81. Carapace, in frontal view; 82. Left male chelicera; 83. Left male palp of holotype, in ventral view; 84. Detail of RTA in retrolateral view; 85–86 Epigyne of paratype, in ventral (85) and dorsal (86) views. Paratypes : 6♀ ( MHBU-ARA-00022223 ), same data as holotype. Etymology. The specific epithet is derived from the type locality. Noun in apposition. Diagnosis. Male is similar to E . nanjiabawa Wang & Zhang, 2023 , but differs in: (1) the much narrower embolic disc; (2) the smaller epigynal window. Female epigyne also shows similarity with E . tianhe Wang & Zhang, 2023 , but can be distinguished by: (1) the smaller epigynal window; (2) the thicker copulatory ducts. FIGURES 87–93.

Epigyne of paratype, in top (91), ventral (92) and dorsal (93) views. Description. Male. Habitus shown in Figs 78, 80 . Carapace length 1.513; abdomen length 1.224. Measurements of eyes: AME 0.295, ALE 0.242, PME 0.071, PLE 0.190. Measurements of legs: I 2.238 (0.751, 0.377, 0.477, 0.346, 0.287), II 1.967 (0.678, 0.323, 0.407, 0.291, 0.268), III 2.368 (0.833, 0.316, 0.467, 0.452, 0.300), IV 2.780 (0.911, 0.365, 0.527, 0.572, 0.405); leg formula: 4312. Color in ethanol: carapace dark, with yellowish-white setae. Abdomen dark, with light bands and patches. Chelicera ( Fig. 82 ) with two promarginal and one retromarginal teeth. Palp ( Figs 83–84 , 87–90 ): femur, patella and tibia covered with dense white setae; embolic disc narrow, plane of embolic disc horizontal in ventral view; CyF developed; RTA straight. Female.

Measurements of legs: I 2.270 (0.762, 0.382, 0.484, 0.351, 0.305), II 1.997 (0.689, 0.328, 0.413, 0.295, 0.272), III 2.531 (0.846, 0.321, 0.474, 0.458, 0.432), IV 2.824 (0.928, 0.370, 0.535, 0.580, 0.411); leg formula: 4312. Color in ethanol: similar to that of male, but with large longitudinal mark behind fovea. Chelicerae as in male. Epigyne (85–86, 91–93): epigynal window located anteriorly, wider than long, posterior margin relatively remote from the genital furrow; copulatory openings located on the posterior margin of the epigynal window; copulatory ducts hidden by the spermathecae in dorsal view; spermathecae globular, entirely posterior to the posterior rim of the epigynal window in ventral view. Distribution. China ( Yunnan ).
