Tong, Yanfeng, Li, Fengyuan, Song, Yang, Chen, Haifeng & Li, Shuqiang, 2019, Thirty-two new species of the genus Speocera Berland, 1914 (Araneae: Ochyroceratidae) from China, Madagascar and Southeast Asia, Zoological Systematics 44 (1), pp. 1-75 : 13-17

Speocera bawangling Li & Li sp. nov. ( Figs 11– 12 , 55E–F )

Material examined. Holotype ♂ ( IZCAS), China, Hainan Province, Changjiang County, Bawangling Natural Reserve , Dong’er protection station (19º5.825′N, 109º10.513′E), elev. 1007m, 11.IV.2012, leg. Z. Chen. Paratypes 3♀ ( IZCAS), same data as holotype .

Etymology. The specific name is derived from the type locality; noun.

Diagnosis. The new species is similar to S. amber Li & Li sp. nov., but males can be distinguished by the long, dark, curved hook like embolus ( Figs 11A–B ) and a palpal tibia that is shorter than the cymbium, and the females by the large oval spermathecae ( Fig. 12A ). S. amber Li & Li sp. nov. males have a very long, ribbon-like, nearly transparent embolus and a palpal tibia that is longer than the cymbium, and females have spiral spermathecae ( Fig. 1 ).

Description. Male. Total length 1.03; carapace length 0.50; carapace width 0.44; abdomen length 0.47; abdomen width 0.39. Prosoma: carapace pyriform, narrowing gradually anteriorly; light yellow, suffused with purplish pattern ( Fig. 12C ); 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 small horn-shaped apophysis; promargin with a series of six teeth reaching the lamina; retromargin with two very small denticles ( Figs 55E–F ). Eyes: six contiguous eyes nearly equal sized, surrounded by black pigmentation ( Fig. 12C ). Opisthosoma oval; purplish. Legs light yellow; leg lengths I 2.03 (0.58, 0.16, 0.61, 0.38, 0.30); II 1.85 (0.54, 0.16, 0.51, 0.35, 0.28); III, IV missing. Genitalia ( Fig. 11 ). Palpal femur long; palpal tibia about 0.8 times as long as cymbium ( Fig. 11A ). Cymbium conical, without prolateral extension. Bulb spherical. Embolus long, dark, curved, hook like and basally with an associated coniform sclerite; sperm duct initially wide, gradually narrowing distally ( Fig. 11D ).

Female. Total length 1.13; carapace length 0.50; carapace width 0.42; abdomen length 0.63; abdomen width 0.56. Similar to male in color and general features ( Figs 12D–E ) but larger. Chelicerae unmodified. Leg lengths I, II missing; III 1.45 (0.39, 0.15, 0.38, 0.29, 0.24); IV 1.92 (0.53, 0.18, 0.53, 0.39, 0.29). Genitalia. Internal genitalia with afferent spermathecae very short, straight, not extending past the sides of the abdomen ( Fig. 12B ); spermathecae large, oval ( Fig. 12A ).

Distribution. Known only from the type locality.
