Type material.

Holotype ♂( IZCAS-Ar40917), China: Yunnan: Xishuangbanna, Mengla County, Menglun Township, XTBG, Leprosy Village, 21.8932N, 101.2883E, elevation ca 550 m, 27.IX.2017, Zhigang Chen, Yunchun Li, Qingyuan Zhao and Jincheng Liu leg. Paratypes 5♂8♀( IZCAS-Ar40918-Ar40930), same data as holotype.

Etymology.

The species is named after Ms. Chen Zeng, who helped us greatly with this research; noun (name) in genitive case.

Diagnosis.

Males of Onomastus chenae   sp. nov. are similar to O. kanoi   Ono, 1995 by having the same shaped spur, a mesal branch of conductor, and a wide conductor. However, O. chenae   sp. nov. can be distinguished by having three apophyses on the median apophysis (vs. two in O. kanoi   ); the epigyne is wider than long (vs. longer than wide in O. kanoi   ), and the copulatory opening is located posteriorly (vs. medially in O. kanoi   ).

Description.

Male (Figs 14A-C View Figure 14 , 15C, E-G View Figure 15 ). Total length 3.66. Carapace 1.60 long, 0.92 wide. Abdomen 2.30 long, 0.75 wide. Clypeus 0.02 high. Eye sizes and inter-distances: AME 0.34, ALE 0.10, PLE 0.12, AERW 0.88, PERW 0.67, EFL 0.47. Legs: I 4.67 (1.28 + 1.85 + 1.00 + 0.44), II 4.55 (1.36 + 1.65 + 1.01 + 0.53), III 4.81 (1.28 + 1.62 + 1.40 + 0.51), IV 5.90 (1.67 + 1.95 + 1.79 + 0.49). Carapace white, black ring around PLEs and PMEs, cephalic part covered with golden setae. Fovea longitudinal, PLEs situated posteriorly. Clypeus white, covered with white setae. Chelicerae white with five promarginal and five retromarginal teeth. Endites, labium and sternum white. Legs white, base of tibia with black spot. Abdomen elongated oval, white.

Palp (Fig. 14A-C View Figure 14 ): Patella with subtriangular patellar apophysis, longer than wide; tibia as long as wide, without retrolateral apophysis; cymbium longer than wide, covered with setae; bulb approximately as long as wide, structure of bulb is complex; sperm duct clearly visible; spur on mesal branch of conductor hook shaped; conductor wide; embolic division occupying large area on bulb with developed conductor; embolus filiform, very long; median apophysis with three apophyses.

Female (Fig. 15A, B, D, E View Figure 15 ). Total length 3.76. Carapace 1.61 long, 1.05 wide. Abdomen 2.2 long, 0.73 wide. Clypeus 0.02 high. Eye sizes and inter-distances: AME 0.36, ALE 0.10, PLE 0.60, AERW 0.99, PERW 0.70, EFL 1.69. Legs: I 4.59 (1.29 + 1.86 + 1.01 + 0.43), II 4.45 (1.31 + 1.70 + 1.02 + 0.42), III 4.89 (1.31 + 1.59 + 1.45 + 0.54), IV 5.96 (1.68 + 1.98 + 1.76 + 0.54). Habitus similar to that of male.

Epigyne (Fig. 15A, B View Figure 15 ) wider than long; transverse copulatory openings sclerotized posteriorly; copulatory ducts and spermathecae visible on epigynal surface, copulatory ducts meandering; spermathecae oval posteriorly.
