Figs 19–31, 258
Type material: Holotype: male, Mt. Diaoluoshan (18°44.505′N, 109°52.104′E, alt. 920 m), Lingshui County, Hainan Island, China, 19 April 2011, leg. Yuanye Zhou. Paratypes: 1 male, 2 females (IZCAS), same data as holotype.
Etymology. The specific name is from Latin gracilis (slender), in reference to the shape of male embolus; adjective.
Diagnosis. Male distinguished from C. acris sp.nov. by the absence of sharp point of tegular apophysis (Figs 19, 25; 1, 5); from C. jianfengensis sp. nov. by the sharp apex of compound teminal apophysis (Figs 19, 25, 26; 32, 38, 39); from C. liaoi (Peng & Li, 2006) and C. setifera sp. nov. by relatively longer embolus (Figs 19, 25; 45, 49; 64, 70). Female differs from the other species in details of epigyne and the routing of copulatory ducts (Figs 21, 22, 27, 28).
Description. Male (Figs 19, 20, 23–26, 29): Total length 1.9, PL 1.0, PW 0.9, OL 0.8, OW 0.75. Eye sizes: AME 0.3, ALE 0.2, PME 0.05, PLE 0.15, AER 0.9, PER 0.8, EFL 0.6. Legs: I 1.95 (0.6, 0.3, 0.45, 0.35, 0.25), II 1.7 (0.55, 0.25, 0.35, 0.35, 0.2), III 1.65 (0.45, 0.25, 0.35, 0.35, 0.25), IV 2.35 (0.75, 0.3, 0.55, 0.45, 0.3); formula: 4123.
Dorsal prosoma light brown, with dark sides, clothed brown and white setae. Clypeus height 0.1, Clypeus gray brown, covered with light 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. Leg I with black longitudinal stripes. Metatarsus I with three pairs of ventral spines. Opisthsoma oval, yellowish brown, with three pairs of black stripes, covered with long brown setae; ventral opisthosoma yellow. Spinnerets light yellow, anterior spinnerets shorter and stronger than posterior ones. Palp (Figs 19, 20, 23–26): Patella and tibia covered with white setae. Embolus slender and convoluted. Tegular apophysis platelike, subrectangular. Median apophysis broad in ventral view.
Female (Figs 21, 22, 27, 28, 30–31): Total length 2.3, PL 1.2, PW 0.95, OL 1.1, OW 1.0. Eye sizes: AME 0.3, ALE 0.2, PME 0.05, PLE 0.16, AER 1.0, PER 0.8, EFL 0.7. Legs: I 2.3 (0.75, 0.35, 0.5, 0.45, 0.25), II 1.9 (0.6, 0.3, 0.4, 0.35, 0.25), III 1.85 (0.55, 0.25, 0.4, 0.4, 0.25), IV 2.8 (0.9, 0.35, 0.7, 0.55, 0.3); formula: 4123. Opisthosoma oval, pale yellow, with four pairs of grayish spots. Other characters similar to those of male. Epigyne (Figs 22, 27): slightly sclerotized, candelabrum-shaped, with long and wide tube medially. Copulatory opening obscured, with a pocket structure. Vulva (Figs 21, 28): Copulatory ducts relatively thin in diameter, long and coiled. Spermathecae oblong.
Distribution. The species is known only from the type locality (Fig. 258).
