Eupoa liaoi Peng & Li 2006: 65, figs 1–3 (female holotype from Hainan, in IZCAS, not examined).

Material examined: 2males, 3 females, Mt. Jingfengling (18°44.415′N, 108°51.802′E, alt. 819 m), Ledong County, Hainan Island, China, 17 May 2011, leg. Yuanye Zhou.

Diagnosis. This species can be distinguished from C. acris sp. nov., C. gracilis sp. nov., C. jianfengensis sp. nov. and C. setifera sp. nov. by the smaller and shorter median apophysis ( Figs 45 View FIGURES 45 – 46 , 49 View FIGURES 47 – 50 ; 1, 5; 19, 25; 32, 38; 64, 70); from C. bawangensis sp. nov. by the slender embolus lacking embolic apophysis ( Figs 45 View FIGURES 45 – 46 , 49 View FIGURES 47 – 50 ; 7, 9, 11); from C. falcata sp. nov. by the shape of tegular apophysis ( Figs 45 View FIGURES 45 – 46 , 49 View FIGURES 47 – 50 ; sickle-shaped in C. falcata sp. nov., Figs 13 View FIGURES 13 – 14 , 17 View FIGURES 15 – 18 ). Female can be distinguished by the shape of epigyne which with a large distinct cap-shaped making, atrium posterior portion semicircular and merged anteriorly.

Description. Male ( Figs 45–50 View FIGURES 45 – 46 View FIGURES 47 – 50 ): Total length 2.1, PL 1.1, PW 0.9, OL 1.0, OW 0.75. Eye sizes: AME 0.25, ALE 0.2, PME 0.04, PLE 0.16, AER 0.9, PER 0.8, EFL 0.7. Legs: I 2.0 (0.6, 0.3, 0.5, 0.35, 0.25), II 1.75 (0.5, 0.25, 0.4, 0.35, 0.25), III 1.7 (0.5, 0.25, 0.35, 0.35, 0.25), IV 2.4 (0.8, 0.3, 0.6, 0.4, 0.3); formula: 4123.

Dorsal prosoma light brown, with dark sides, clothed brown and white setae. Clypeus height 0.05, Clypeus gray brown, covered with long 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 black spots, following one black latitudinal stripe; anterior and posterior margins covered with long brown setae; ventral opisthosoma light yellow. Spinnerets light yellow, anterior spinnerets shorter and stronger than posterior ones. Palp ( Figs 45–49 View FIGURES 45 – 46 View FIGURES 47 – 50 ): Embolus relatively short, originating from the median part of the bulbus. Embolic base with erect apophysis. Tegular apophysis cone-shaped. Median apophysis fingerlike.

Distribution. China (Hainan).

Remark. Peng & Li (2006) described Eupoa liaoi as a new species to science according to a female collected from Mt. Jianfengling, Ledong County, Hainan Island. They assigned it to the genus Eupoa due to the body form and markings. Eupoa is a genus of dark opisthosoma with light segments, and with separated copulatory ducts in type species. The merged copulatory ducts and the newly discovered male suggested that Eupoa liaoi Peng & Li should actually be better placed in Corusca . We examined specimens of E. liaoi collected from Mt. Jianfengling, and considering the account and illustrations in the original paper, we transfer it to Corusca here.
