Treatment

Speocera xiaoxiaoae Li & Li View in CoL sp. nov. ( Figs 49– 50 View Figure 49 View Figure 50 , 57E–F View Figure 57 )

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 GoogleMaps .

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 View Figure 49 ), the long, slender horn-shaped apophysis of the male chelicerae ( Figs 57E–F View Figure 57 ), and the very long afferent spermathecae and elongated oval spermathecae ( Figs 50A–B View Figure 50 ). S. zhigangi males have an incrassate palpal tibia and cymbium ( Figs 53A–B View Figure 53 ), large, blunt, horn-shaped apophysis on the chelicerae ( Figs 57G–H View Figure 57 ), and the females have short afferent spermathecae and small oval spermathecae ( Figs 54A–B View Figure 54 ).

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 View Figure 50 ); 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 View Figure 57 ). Eyes: six contiguous eyes surrounded by black pigmentation, PME smallest, PLE largest ( Fig. 50C View Figure 50 ). 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 View Figure 49 ). Palpal femur long; palpal tibia as long as cymbium ( Figs 49A–B View Figure 49 ). Cymbium conical, with small prolateral extension basally. Bulb spherical. Embolus small, dark, associated sclerites absent; sperm duct initially wide gradually narrowing distally ( Fig. 49D View Figure 49 ).

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 View Figure 50 ). 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 View Figure 50 ); spermathecae elongated, oval ( Fig. 50A View Figure 50 ).
