Etymology. The specific name comes from the Latin word “ globosus ”, referring to the shape of the male pedipalpal bulb; adjective

Diagnosis. The new species is similar to C. qiyunensis Xu, Yang & Song, 2003 (Wu & Zhang, 2014: 211, figs 13–23). Males differ from the latter by the strong femoral apophysis, longer than femoral width, and the tiny embolus ( Figs 6A–C , 7C–E ) (femoral apophysis shorter than femoral width, spine-like embolus of C. qiyunensis ). Females differ by the oval copulatory opening (roundish in C. qiyunensis ) ( Figs 6D , 7F, 7H ). Males of this new species are also similar to that of C. pollicaris Wu, Zheng & Zhang, 2015 (Wu, Zheng & Zhang, 2015: 20, figs 15–16, 19, 25–27), but differ from the latter by the femoral apophysis shorter than two times of femoral width (longer than two times of femoral width in C. pollicaris ).

Clypeus height 0.05. Chelicerae yellow brown, with 6 promarginal and 4 retromarginal teeth. Gnathocoxae yellow brown, longer than wide. Labium yellow brown, longer than wide. Sternum yellowish brown, heartshaped, with sparse brown hairs. Pairs of ventral spines: Tibia I 2; Metatarsus I 1; Tibia II 2; Metatarsus II 1. Leg measurements: I 4.38 (1.28, 1.72, 0.86, 0.52); II 4.97 (1.48, 2.01, 0.93, 0.55); III 4.12 (1.19, 1.43, 1.03, 0.47); IV 5.92 (1.69, 2.03, 1.56, 0.64). Leg formula 4213. Abdomen oval. Both dorsum and venter yellow brown.

Male pedipalp ( Figs 6A–C , 7C–E ). Femoral apophysis strong, 5 times longer than basal width. Patella with blunt and wide prolateral apophysis, its width about 1/2 of patellar diameter. RTA small and blunt, located distally. Bulb nearly spherical, widest proximally. Embolus arising from tegulum distally, very small. Sperm duct narrow.

Female paratypes total length 5.23–7.09. One of them ( Fig. 7B ) total length 6.71. Carapace 2.38 long, 1.84 wide; abdomen 4.21 long, 2.42 wide. Eye sizes and interdistances: AME 0.09, ALE 0.14, PME 0.11, PLE 0.14; AME–AME 0.09, AME–ALE 0.06, PME–PME 0.28, PME–PLE 0.15, ALE–PLE 0.09. MOA 0.38 long, front width 0.30, back width 0.52. Clypeus height 0.07. Chelicerae with 4 promarginal and 6 retromarginal teeth. Leg measurements: I 5.11 (1.46, 2.04, 1.00, 0.61); II 5.86 (1.75, 2.33, 1.15, 0.63); III 4.93 (1.46, 1.69, 1.24, 0.54); IV 7.18 (2.02, 2.49, 2.00, 0.67). Leg formula 4213. Other characters as in male.

Epigyne ( Figs 6D–E , 7F–I ). Copulatory opening small, located centrally. Copulatory ducts strongly twisted, connected with a pair of large, transparent, oval bursae and tube-like spermathecae. Fertilization ducts small.

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

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