Type material: Holotype: male, Mt. Diaoluoshan (18°40.145′N, 109°52.718′E, alt. 580 m), Lingshui County, Hainan Island, China, 16 April 2009, leg. Guo Tang.

Etymology. This specific name is from Latin falcatus (sickle-shaped), in reference to the shape of tegular apophysis of male bulbus; adjective.

Diagnosis. This new species can be distinguished from other species as follows: from C. acris sp. nov., C. gracilis sp. nov., C. jianfengensis sp. nov., C. liaoi (Peng & Li, 2006) and C. setifera sp. nov. by the smaller and shorter median apophysis ( Figs 13 , 17 ; 1, 5; 19, 25; 32, 38; 45, 49; 64, 70); from C. bawangensis sp. nov. and C. sanyaensis sp. nov. by the bent and wider tegular apophysis ( Figs 13 , 17 ; 7, 11; 51, 57).

Description. Male ( Figs 13–18 ): Total length 1.7, PL 1.0, PW 0.85, OL 0.75, OW 0.6. Eye sizes: AME 0.25, ALE 0.2, PME 0.05, PLE 0.15, AER 0.85, PER 0.75, EFL 0.5. Legs: I 1.75 (0.6, 0.25, 0.4, 0.3, 0.2), II 1.45 (0.45, 0.25, 0.3, 0.25, 0.2), III 1.45 (0.45, 0.2, 0.3, 0.3, 0.2), IV 2.05 (0.7, 0.25, 0.5, 0.35, 0.25); formula: 4132.

Dorsal prosoma light brown, with dark sides, clothed with brown and white setae. Clypeus height 0.05, Clypeus gray brown, covered with brown setae. Fovea, cervicle and radial grooves unclear. Chelicerae small and yellow, with two promarginal teeth, retromargin with four teeth. Endites, labium and sternum yellow. Leg I with black longitudinal stripes. Metatarsus I with three pairs of ventral spines. Opisthosoma cylindrical, yellowish brown, with three pairs of balck latitudinal stripes, following one dark latitudinal stripe; anterior and posterior margins covered with long brown setae; ventral opisthosoma yellow. Spinnerets light yellow, anterior spinnerets shorter and stronger than posterior ones. Palp ( Figs 13–17 ): Embolus thin and long, U-shaped distally. Compound teminal apophysis broad and arched. Tegular apophysis sickle-shaped. Median apophysis moderately size with a little twisty.

Female: Unknown.

Distribution. The species is known only from the type locality ( Fig. 258 ).
