Figs 1–6 , 258

Type material: Holotype: male, Mt. Bawangling (19°05.753′N, 109°10.557′E, alt. 825 m), Hainan Island, China, 24 July 2007, leg. Shuqiang Li.

Etymology. The specific name is from Latin acer (pointed, sharp), in reference to the sharply pointed median apophysis; adjective.

Diagnosis. This new species can be distinguished by the shape of male median apophysis, which is relatively large and transverse ( Figs 1 , 5 ), smaller in C. bawangensis sp. nov., C. falcata sp. nov. and C. sanyaensis sp. nov. ( Figs 7 , 11 ; 13, 17; 51, 57), erect in C. viriosa sp. nov. and C. wuzhishanensis sp. nov. ( Figs 77 , 83 ; 92, 98). Further distinguished by the shape of tegular apophysis ( Figs 1 , 5 ), which with two sharp points in ventral view, while there is only one point in C. jianfengensis sp. nov. and C. liaoi (Peng & Li, 2006) ( Figs 32 , 38 ; 45, 49), and with no pointed tip in C. gracilis sp. nov. ( Figs 19 , 25 ).

Description. Male ( Figs 1–6 ): Total length 1.75, PL 1.0, PW 0.8, OL 0.75, OW 0.65. Eye sizes: AME 0.25, ALE 0.17, PME 0.04, PLE 0.15, AER 0.85, PER 0.7, EFL 0.6. Legs: I 1.75 (0.55, 0 25, 0.4, 0.35, 0.2), II 1.55 (0.45, 0.25, 0.35, 0.3, 0.2), III 1.5 (0.45, 0.2, 0.3, 0.3, 0.25), IV 2.1 (0.7, 0.2, 0.55, 0.4, 0.25); formula: 4123.

Dorsal prosoma light brown, with dark sides, covered with brown and white setae. Clypeus height 0.1, 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 spots. Metatarsus I with three pairs of ventral spines. Opisthosoma cylindrical, yellowish brown, with two pairs of grayish black latitudinal stripes; 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 1–5 ): Embolus relatively long, originating from the median part of bulb, convoluted. Compound terminal apophysis knife-like. Tegular apophysis with two pointed apophyses in ventral view. Median apophysis bent upward, apex pointed.

Female: Unknown.

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