Clubiona huiming Wang, Zhang & Zhang , sp. nov. ( Figs 8A–B , 9A–C )

Material examined. Holotype ♂, China, Guizhou, Fanjing Mountain Reserve, Mianxuling (27°54.54′N, 108°39.83′E; elev. 1974 m), 30.IX.2013, L.Y. Wang, D. Wang & X.K. Jiang leg. Paratype. 1♂, between Jinding and Jiandaoxia, 13.X.2014, C. Jin & Z.Z. Gao leg.

Etymology. The specific name honours Dr. Huiming Chen , a researcher on biospeleology and local animal resource of Guizhou, China; noun.

Diagnosis. Males of the new species are similar to C. subapplanata Wang, Chen & Zhang ZS , sp. nov. ( Figs 14A–B , 15A, C–F ), but differs from the latter by the VTA as long as wide, the long and slender embolus and the tapering and coiled conductor ( Figs 8A–B , 9B–C ) ( VTA wider than long, embolus short and conductor reduced in C. subapplanata Wang, Chen & Zhang ZS , sp. nov.).

Description. Male ( Fig. 9A ). Holotype total length 4.16. Carapace 2.10 long, 1.58 wide; abdomen 2.07 long, 1.27 wide. Carapace yellowish brown. Eye sizes and interdistances: AME 0.08, ALE 0.14, PME 0.12, PLE 0.14; AME–AME 0.07, AME–ALE 0.04, PME–PME 0.17, PME–PLE 0.10, ALE–PLE 0.05. MOA 0.31 long, front width 0.25, back width 0.40. Clypeus height 0.07. Chelicerae yellow brown, with 5 promarginal and 5 retromarginal teeth. Pairs of ventral spines: Tibia I 3; Metatarsus I 1; Tibia II 3; Metatarsus II 1. Leg measurements: I 4.92 (1.42, 1.98, 0.96, 0.56); II 5.35 (1.61, 2.13, 1.01, 0.60); III 4.57 (1.34, 1.62, 1.11, 0.50); IV 6.58 (1.96, 2.09, 1.94, 0.59). Leg formula 4213. Abdomen yellowish brown.

Male pedipalp ( Figs 8A–B , 9B–C ). Femur without apophysis. Patella longer than wide. Tibia shorter than patella, with 3 apophyses. RTA almost conical, located distally. VTA almost as long as wide. LTA wide and short, located proximally. Embolus long and coiled, arising distally from tegulum. Conductor wide in mid-part and tapering toward its apex. Sperm duct U-shaped.

Female. Unknown.

Distribution. Known only from the type locality, Guizhou, China.
