Clubiona subcylindrata Wang, Chen & Zhang ZS , sp. nov. ( Figs 16A–C , 17A–D )

Material examined. Holotype ♂, China, Guizhou, Fanjing Mountain Reserve, Heiwanhe (27°50.778′N, 108°46.362′E; elev. 533 m), 26.IX.2013, L.Y. Wang, D. Wang & X.K. Jiang leg.

Etymology. The specific name is taken from its similarity to C. cylindrata Liu, Yan, Griswold & Ubick, 2007 ; adjective.

Diagnosis. The new species is similar to C. cylindrata Liu, Yan, Griswold & Ubick, 2007 ( Liu et al., 2007: 67, figs 11– 15), but differs from the latter by the RTA wider than a half of its length, much wider, membranous conductor ( Figs 16A–C , 17B–D ) (width of RTA less than a half of its length and slender, indistinct conductor in C. cylindrata ).

Description. Male ( Fig. 17A ). Holotype total length 8.72. Carapace 3.72 long, 2.72 wide; abdomen 5.12 long, 2.23 wide. Eye sizes and interdistances: AME 0.16, ALE 0.20, PME 0.17, PLE 0.17; AME–AME 0.17, AME–ALE 0.07, PME– PME 0.34, PME–PLE 0.24, ALE–PLE 0.12. MOA 0.50 long, front width 0.49, back width 0.67. Clypeus height 0.10. Chelicerae with 4 promarginal and 2 retromarginal teeth. Pairs of ventral spines: Tibia I 2; Metatarsus I 1; Tibia II 2; Metatarsus II 1. Leg measurements: I 10.50 (2.88, 4.16, 2.24, 1.22); II 11.74 (3.13, 4.73, 2.53, 1.35); III 9.21 (2.61, 3.33, 2.44, 0.83); IV 12.08 (3.02, 4.08, 3.78, 1.20). Leg formula 4213. Abdomen yellow brown.

Male pedipalp ( Figs 16A–C , 17B–D ). Femur and patella without apophysas. Patella and tibia almost 2 times longer than wide. Tibia with two apophyses: RTA short, with slightly peaked apex; VTA small, slightly wider than long. Conductor membranous, wide and slightly folded. Embolus slender, arising prolaterally, extending distally. Part of sperm duct visible on disto-retrolateral side of tegulum.

Female. Unknown.

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

Comment. The new species belongs to the C. corticalis- group.
