Type material: Holotype: male, Liuhe Town (18°10.645′N, 109°33.989′E, alt. 5 m), Sanya City, Hainan Island, China, 15 July 2007, leg. Chunxia Wang. Paratypes: 2 females (IZCAS), same data as holotype.

Etymology. The specific name refers to the type locality; adjective.

Diagnosis. Male can be distinguished from C. bawangensis sp. nov. by the lack of embolic apophysis ( Figs 51 View FIGURES 51 – 54 , 57 View FIGURES 55 – 58 ; 7, 11); from C. gracilis sp. nov. by having a smaller median apophysis ( Figs 51 View FIGURES 51 – 54 , 57 View FIGURES 55 – 58 ; 19, 25, 26); from other species by the relatively long tegular apophysis. Female differs from C. gracilis sp. nov. by having large spiral of copulatory ducts ( Figs 53 View FIGURES 51 – 54 , 60 View FIGURES 59 – 63 ; 21, 28); distinguished from C. jianfenginsis sp. nov. and C. setifera sp. nov. by having longer copulatory ducts which are thinner ( Figs 53 View FIGURES 51 – 54 , 60 View FIGURES 59 – 63 ; 35, 41; 67, 73).

Description. Male ( Figs 51, 52 View FIGURES 51 – 54 , 55–58 View FIGURES 55 – 58 , 61 View FIGURES 59 – 63 ): Total length 1.6, PL 0.9, PW 0.7, OL 0.7, OW 0.55. Eye sizes: AME 0.2, ALE 0.16, PME 0.05, PLE 0.15, AER 0.8, PER 0.7, EFL 0.6. Legs: I 1.6 (0.5, 0.25, 0.35, 0.3, 0.2), II 1.45 (0.4, 0.2, 0.4, 0.25, 0.2), III 1.3 (0.4, 0.15, 0.3, 0.25, 0.2), IV 1.7 (0.6, 0.25, 0.4, 0.35, 0.2); formula: 4123.

Dorsal prosoma light brown, with dark sides, clothed brown and white setae. Clypeus height 0.06, Clypeus gray brown, covered with long brown setae. Fovea, cervicle and radial grooves unclear. Chelicerae small and yellow, with two promarginal teeth, retromargin with three teeth. Endites, labium and sternum yellow. Legs I with black spot. Metatarsus I with three pairs of ventral spines. Opisthosoma cylindrical, yellowish brown, with three pairs of black spots, following one black latitudinal stripe; anterior and posterior margins covered with brown setae; ventral opisthosoma yellow. Spinnerets light yellow, anterior spinnerets shorter and stronger than posterior ones. Palp ( Figs 51, 52 View FIGURES 51 – 54 , 55–58 View FIGURES 55 – 58 ): Embolus slender, forming a loop. Embolic base with a triangular apophysis. Tegular apophysis slender, curved with an acuminated apex, extending towards tip of bulbus. Median apophysis moderately size, terminates with a small hook.

Female ( Figs 53, 54 View FIGURES 51 – 54 , 59, 60, 62, 63 View FIGURES 59 – 63 ): Total length 1.9, PL 1.0, PW 0.8, OL 0.9, OW 0.85. Eye sizes: AME 0.25, ALE 0.2, PME 0.04, PLE 0.16, AER 0.82, PER 0.75, EFL 0.55. Legs: I 1.75 (0.55, 0.25, 0.4, 0.35, 0.2), II 1.45 (0.45, 0.2, 0.3, 0.3, 0.2), III 1.45 (0.45, 0.2, 0.3, 0.3, 0.2), IV 2.2 (0.75, 0.25, 0.55, 0.4, 0.25); formula: 4132.

Opisthosoma oval, yellow, with three pairs of pale gray spots, following one gray latitudinal stripe. Other characters similar to those of male. Epigyne ( Figs 54 View FIGURES 51 – 54 , 59 View FIGURES 59 – 63 ): weakly sclerotized, crown-shaped. Copulatory opening obscured, with a pocket structure. Vulva ( Figs 53 View FIGURES 51 – 54 , 60 View FIGURES 59 – 63 ): Copulatory ducts twisted and folded, merged and extending into the pocket structure. Spermathecae small and oval.
