Figures 3 A–D, 4A–G, 12

Type material. Holotype male, China, Hunan Prov., Changsha City, Wangcheng District, Heimifeng Forest Park , 28°27′46″ N, 113°00′53″ E, elev. 518 m, 25 November 2017, K.K. Liu and L.Y. Wang leg. , Paratypes: 1 male, 1 female, with same data as for holotype .

Etymology. The specific name comes from the first name of the collector; noun in genitive case.

Diagnosis. The new species is similar to C. calyciforma Wang & Xu, 1989 ( Figs 11 C–G, female holotype, male paratype from Mt. Qiyun, Huangshan City, Anhui Prov., China, deposited in HNU, examined) in having strong RTA, long embolus, modified conductor, anteriorly located copulatory openings and the same extending direction of copulatory ducts of epigyne, but differs from the latter by the relatively shaped end of RTA, the different shape of the end of conductor ( Figs 3 A–B, 4C–E), the transversely narrow epigynal atrium, the relatively short copulatory ducts and the almost rounded spermathecae ( Figs 3 C–D, 4F–G).

Description. Male. Total length 3.29–3.87. Holotype ( Fig. 4A ) total length 3.29. Prosoma 1.77 long, 1.40 wide; Opisthosoma 1.40 long, 1.21 wide. Eye sizes and interdistances: AME 0.03, ALE 0.09, PME 0.08, PLE 0.09; AME–AME 0.03, AME–ALE 0.02, PME–PME 0.07, PME–PLE 0.04, ALE–PLE 0.05. MOA 0.19 long, anterior width 0.07, posterior width 0.23. Clypeus height 0.12. Chelicerae with 3 promarginal and 8 retromarginal teeth. Leg measurements: I 5.24 (1.47, 1.81, 1.15, 0.81); II 4.46 (1.28, 1.46, 0.98, 0.74); III 4.01 (1.12, 1.27, 0.95, 0.67); IV 5.26 (1.44, 1.72, 1.35, 0.75).

Male pedipalp ( Figs 3 A–B, 4C–E). RTA strong, with a single fold and rounded apex, approaching the mid-part of cymbium. The base of RTA with two small apophyses, extending ventrally and dorsally. Embolus originating at approximately 7-o’clock position. Embolus slender, its anterior part resting in the long groove of conductor. Conductor strong, with an arch-like end.

Female ( Fig. 4B ) total length 3.87. Prosoma 1.72 long, 1.14 wide; opisthosoma 1.89 long, 1.57 wide. Eye sizes and interdistances: AME 0.03, ALE 0.08, PME 0.07, PLE 0.08; AME–AME 0.02, AME–ALE 0.02, PME–PME 0.08, PME–PLE 0.05, ALE–PLE 0.05. MOA 0.19 long, anterior width 0.07, posterior width 0.22. Clypeus height 0.11. Leg measurements: I 4.57 (1.31, 1.60, 0.91, 0.75); II 4.00 (1.15, 1.39, 0.89, 0.57); III 3.67 (1.04, 1.21, 0.89, 0.53); IV 5.01 (1.37, 1.74, 1.19, 0.71).

Epigyne ( Figs 3 C–D, 4F–G). Atrium small and archway-like. Copulatory openings located on the shoulders of atrium. Copulatory ducts long and spiral. Spermathecae large and ball-shaped. Fertilization ducts small.

Distribution. Known only from the type locality, Hunan, China ( Fig. 12 ).
