description: <i>Speocera xiaoxiaoae</i> Li &amp; Li sp. nov. (Figs 49– 50, 57E–F) Material examined. Holotype &amp;male; (IZCAS), China, Hainan Province, Tunchang County, Datong Town, Wolongshan Hill (19º27.545′N, 110º7.315′E), elev. 248m, 6.VII.2014, leg. F. Li &amp; X. Wang. Paratypes 2&amp;male; 2&amp;female; (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 <i>S. zhigangi</i> Li &amp; Li <b>sp. nov.</b> 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). <i>S. zhigangi</i> 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).
