Type material: Holotype: male, Mt. Wuzhishan (18°54.418′N, 109°40.647′E, alt. 941 m), Hainan Island, China, 28 April 2011, leg. Yuanye Zhou. Paratypes: 4 males, 3 females (IZCAS), same data as holotype. Etymology. The specific name is from Latin viriosus (strong), in reference to the large size of the species; adjective.

Diagnosis. Male differs from C. acris sp. nov., C. bawangensis sp. nov., C. falcata sp. nov., C. gracilis sp.

nov., C. jianfengensis sp. nov., C. liaoi (Peng & Li, 2006), C. sanyaensis sp. nov. and C. setifera sp. nov. by having a large patellar apophysis ( Figs 77 View FIGURES 77 – 80 , 83 View FIGURES 81 – 84 ; 1, 5; 7, 11; 13, 17; 19, 25; 32, 38; 45, 49; 51, 57; 64, 70); differs from C. wuzhishanensis sp. nov. by having a branched patellar apophysis, and the two branches of median apophysis which are approximately equal in length ( Figs 77 View FIGURES 77 – 80 , 83 View FIGURES 81 – 84 ; 92, 98). Female can be distinguished from C. wuzhishanensis sp. nov. by the proportion of epigyne length and width ( Figs 80 View FIGURES 77 – 80 , 85 View FIGURES 85 – 89 ; wider than longer in C. wuzhishanensis sp. nov., Figs 94 View FIGURES 92 – 95 , 100 View FIGURES 100 – 104 ).

Description. Male ( Figs 77, 78 View FIGURES 77 – 80 , 81–84 View FIGURES 81 – 84 , 87 View FIGURES 85 – 89 ): Total length 2.35, PL 1.25, PW 1.0, OL 1.1, OW 0.8. Eye sizes: AME 0.3, ALE 0.2, PME 0.05, PLE 0.2, AER 1.05, PER 0.9, EFL 0.8. Legs: I 2.4 (0.7, 0.35, 0.6, 0.5, 0.25), II 2.0 (0.6, 0.3, 0.45, 0.4, 0.25), III 2.0 (0.6, 0.25, 0.4, 0.45, 0.3), IV 2.85 (1.0, 0.3, 0.7, 0.5, 0.35); formula: 4132.

Dorsal prosoma light brown, with dark sides, anterior portion black, covered with white setae. Clypeus height 0.2, Clypeus gray brown, covered with white setae. Fovea, cervicle and radial grooves unclear. Chelicerae small and yellow, with one promarginal teeth, retromargin with four teeth. Endites, labium and sternum yellow. Leg I to III with black longitudinal stripes. Metatarsus I with three pairs of ventral spines. Opisthosoma cylindrical, yellowish brown, with irregular black spots; anterior and posterior margins covered with brown setae; ventral opisthosoma yellow; booklungs black. Spinnerets light yellow, anterior spinnerets shorter and stronger than posterior ones. Palp ( Figs 77, 78 View FIGURES 77 – 80 , 81–84 View FIGURES 81 – 84 ): Patellar apophysis broad, with a sheet apophysis proximally. Tibial apophysis long, extending towards median bulbus. Embolus long, bifurcated on tip of bulbus. Median apophysis bent, bifurcated.

Female ( Figs 79, 80 View FIGURES 77 – 80 , 85, 86, 88, 89 View FIGURES 85 – 89 ): Total length 3.0, PL 1.5, PW 1.1, OL 1.5, OW 1.3. Eye sizes: AME 0.35, ALE 0.25, PME 0.05, PLE 0.2, AER 1.15, PER 0.9, EFL 0.8. Legs: I 2.95 (0.9, 0.4, 0.7, 0.6, 0.35), II 2.25 (0.7, 0.35, 0.4, 0.5, 0.3), III 2.4 (0.7, 0.3, 0.5, 0.55, 0.35), IV 3.5 (1.1, 0.4, 0.9, 0.7, 0.4); formula: 4132.

Opisthosoma oval, yellowish, with irregular gray spots familiar to male, anterior portion covered with long brown setae. Other characters similar to those of male. Epigyne ( Figs 80 View FIGURES 77 – 80 , 85 View FIGURES 85 – 89 ): moderately sclerotized, swollen medially, with two auriform apophyses. Copulatory openings invisible. Vulva ( Figs 79 View FIGURES 77 – 80 , 86 View FIGURES 85 – 89 ): complicated, with long membranaceous and folded copulatory ducts. Spermathecae oval.

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