Type material: Holotype: male, Mt. Wuzhishan (18°54.418′N, 109°40.647′E, alt. 941 m), Hainan Island, China, 30 April 2011, leg. Yuanye Zhou. Paratypes: 2 males, 2 females (IZCAS), same data as holotype.

Etymology. The specific name is from Latin setifer (setaceous), in reference to the setaceous tibia of male palp; adjective.

Diagnosis. Male can be distinguished from C. bawangensis sp. nov., C. falcata sp. nov., C. liaoi (Peng & Li, 2006) and C. sanyaensis sp. nov. by the large median apophysis, which bend upward ( Figs 64 View FIGURES 64 – 67 , 70 View FIGURES 68 – 71 ; 7, 11; 13, 17; 45, 49; 51, 57); from C. viriosa sp. nov. and C. wuzhishanensis sp. nov. by the lack of patellar apophysis, and with shorter tibial apophysis ( Figs 64 View FIGURES 64 – 67 , 70 View FIGURES 68 – 71 ; tibial apophysis approximately half length of bulbus, as long as patellar apophysis in C. viriosa sp. nov. and E. wuzhishanensis sp. nov., Figs 77 View FIGURES 77 – 80 , 83 View FIGURES 81 – 84 ; 92, 98); from C. acris sp. nov., C. gracilis sp. nov. and C. jianfengensis sp. nov. by the relatively short embolus and the shape of tegular apophysis which is pointed at tip ( Figs 64 View FIGURES 64 – 67 , 71 View FIGURES 68 – 71 ; 1, 5; 19, 25, 26; 32, 38, 39). Female differs from other species by the atrium that opened at middle of epigyne ( Figs 66 View FIGURES 64 – 67 , 72 View FIGURES 72 – 76 ; at the bottom of epigyne in other Corusca species).

Description. Male ( Figs 64, 65 View FIGURES 64 – 67 , 68–71 View FIGURES 68 – 71 , 74 View FIGURES 72 – 76 ): Total length 1.8, PL 1.0, PW 0.8, OL 0.8, OW 0.7. Eye sizes: AME 0.21, ALE 0.17, PME 0.04, PLE 0.14, AER 1.02, EFL 0.5. Legs: I 1.8 (0.5, 0.3, 0.4, 0.4, 0.2), II 1.57 (0.45, 0.2, 0.42, 0.3, 0.2), III 1.54 (0.45, 0.2, 0.35, 0.3, 0.24), IV 2.05 (0.7, 0.2, 0.5, 0.4, 0.25); formula: 4123.

Dorsal prosoma light brown, with dark sides, covered with brown and white setae. Clypeus height 0.06, Clypeus gray brown, covered with grayish brown setae. Fovea, cervicle and radial grooves unclear. Chelicerae small and yellow, with one promarginal teeth, retromargin with two teeth. Endites, labium and sternum yellow. Legs yellow with black longitudinal stripes. Metatarsus I with three pairs of ventral spines. Opisthosoma oval, yellowish brown, with three pairs of irregular grayish black spots; anterior and posterior margins covered with short brown setae; ventral opisthosoma yellow. Spinnerets light yellowish white, anterior spinnerets shorter and stronger than posterior ones. Palp ( Figs 64, 65 View FIGURES 64 – 67 , 68–71 View FIGURES 68 – 71 ): Patella and tibia covered with long white setae. Embolus whip-shaped, forming a loop. Tegular apophysis curved with an acuminated apex, extending towards tip of bulbus. Median apophysis axe-shaped in ventral view.

Female ( Figs 66, 67 View FIGURES 64 – 67 , 72, 73, 75, 76 View FIGURES 72 – 76 ): Total length 2.6, PL 1.15, PW 0.95, OL 1.2, OW 1.1. Eye sizes: AME 0.27, ALE 0.18, PME 0.05, PLE 0.2, AER 0.95, PER 0.82, EFL 0.7. Legs: I 1.9 (0.7, 0.3, 0.4, 0.3, 0.2), II 1.55 (0.5, 0.2, 0.3, 0.35, 0.2), III 1.8 (0.6, 0.3, 0.3, 0.35, 0.25), IV 2.65 (0.9, 0.3, 0.7, 0.45, 0.3); formula: 4132

Opisthosoma oval, yellowish white, with three gray latitudinal stripes; anterior covered with long brown setae and posterior covered with densely short setae. Other characters similar to those of male. Epigyne ( Figs 66 View FIGURES 64 – 67 , 72 View FIGURES 72 – 76 ): weakly sclerotized, pot-shaped, with a groove leading to the compulatory openings. Copulatory openings obscured. Vulva ( Figs 67 View FIGURES 64 – 67 , 73 View FIGURES 72 – 76 ): Copulatory ducts thick-walled, folded, merged and extengding towards the groove. Spermathecae diamond.

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