Abstract

Speocera xiaoxiaoae Li & Li sp. nov. (Figs 49– 50, 57E–F) Material examined. Holotype ♂ (IZCAS), China, Hainan Province, Tunchang County, Datong Town, Wolongshan Hill (19º27.545′N, 110º7.315′E), elev. 248m, 6.VII.2014, leg. F. Li & X. Wang. Paratypes 2♂ 2♀ (IZCAS), same data as holotype. Etymology. The specific name is taken after one of the collectors, Miss Xiaoxiao Wang; name in genitive case. Diagnosis. The new species is similar to S. zhigangi Li & Li sp. nov. but can be distinguished by the slender male palpal tibia and cymbium (Figs 49A–B), the long, slender horn-shaped apophysis of the male chelicerae (Figs 57E–F), and the very long afferent spermathecae and elongated oval spermathecae (Figs 50A–B). S. zhigangi males have an incrassate palpal tibia and cymbium (Figs 53A–B), large, blunt, horn-shaped apophysis on the chelicerae (Figs 57G–H), and the females have short afferent spermathecae and small oval spermathecae (Figs 54A–B). Description. Male. Total length 1.08; carapace length 0.50; carapace width 0.43; abdomen length 0.58; abdomen width 0.39. Prosoma: carapace pyriform, narrowing gradually anteriorly; light yellow, suffused with purplish pattern (Fig. 50C); pars cephalica flat; fovea not visible. Sternum light yellow, suffused with purplish color, as long as wide. Endites light yellow with serrula; labium light yellow. Clypeus nearly vertical; short. Chelicerae light yellow, laterally strongly excavated, with a long, slender horn-shaped apophysis; promargin with a series of six teeth reaching the lamina; retromargin with two very small denticles (Figs 57E–F). Eyes: six contiguous eyes surrounded by black pigmentation, PME smallest, PLE largest (Fig. 50C). Opisthosoma oval; purplish. Legs light yellow; leg lengths I 1.92 (0.56, 0.16, 0.56, 0.36, 0.28); II 1.70 (0.48, 0.15, 0.48, 0.33, 0.27); III, IV missing. Genitalia (Fig. 49). Palpal femur long; palpal tibia as long as cymbium (Figs 49A–B). Cymbium conical, with small prolateral extension basally. Bulb spherical. Embolus small, dark, associated sclerites absent; sperm duct initially wide gradually narrowing distally (Fig. 49D). Female. Total length 1.09; carapace length 0.49; carapace width 0.43; abdomen length 0.59; abdomen width 0.41. Similar to male in color and general features (Figs 50D–E). Chelicerae unmodified. Leg formula 4123; leg lengths I 1.85 (0.52, 0.17, 0.53, 0.36, 0.27); II 1.67 (0.48, 0.16, 0.45, 0.32, 0.27); III 1.46 (0.42, 0.13, 0.37, 0.30, 0.25); IV 1.93 (0.53, 0.16, 0.56, 0.41, 0.28). Genitalia. Internal genitalia with afferent spermathecae long, straight, extending past the sides of the abdomen (Fig. 50B); spermathecae elongated, oval (Fig. 50A). Distribution.
