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 : 52

Speocera suea Li & Li sp. nov. ( Figs 40–41 , 57B )

Material examined. Holotype ♂ ( IZCAS), Thailand, Yala Province, Mueang Yala District, Outside of Suea Cave (6º31.355′N, 101º13.865′E), elev. 43 m, 20.X.2015, leg. Q. Zhao, G. Zhou & Z. Chen. Paratypes 1♂ 1♀ ( IZCAS), same data as holotype .

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

Diagnosis. Males of the new species are similar to S. ranongensis Deeleman-Reinhold, 1995 (female unknown) but can be distinguished by the distinctly short palpal tibia that is about 1.2 times as long as the cymbium in the new species ( Fig. 40A ) vs two times longer than the cymbium in S. ranongensis (Deeleman-Reinhold, 1995: fig. 272); females of the new species are similar to S. capra Deeleman-Reinhold, 1995 but can be distinguished by the tubular spermathecae ( Fig. 41A ).

Description. Male. Total length 0.94; carapace length 0.38; carapace width 0.45; abdomen length 0.47; abdomen width 0.33. Prosoma: carapace broadly oval, narrowing gradually anteriorly; shiny, light yellow, suffused with purplish pattern ( Fig. 41C ); pars cephalica flat; fovea not visible. Sternum brown, as long as wide. Endites light yellow, suffused with purplish tinge; with serrula; labium light yellow, suffused with purplish tinge. Clypeus nearly vertical; short. Chelicerae light yellow, lateral margin slightly curved, with several setae; promargin with a series of six teeth reaching the lamina; retromargin with two very small denticles ( Fig. 57B ). Eyes: six contiguous eyes surrounded by black pigmentation; PME smallest, ALE largest ( Fig. 41C ). Opisthosoma oval; purplish. Legs light yellow; leg lengths I, II, III missing; IV 1.94 (0.54, 0.14, 0.54, 0.43, 0.29). Genitalia ( Fig. 40 ). Palpal femur long; palpal tibia about 1.2 times as long as cymbium. Cymbium conical, without prolateral extension. Bulb spherical, wider than high. Embolus ribbon-like, dark and basally with two long associated sclerites; sperm duct initially wide, narrowing distally ( Fig. 40D ).

Female. Total length 1.11; carapace length 0.50; carapace width 0.42; abdomen length 0.54; abdomen width 0.45. Similar to male in color and general features ( Figs 41D–E ) but larger. Chelicerae unmodified. Leg formula 4123; leg lengths I 1.81 (0.51, 0.15, 0.53, 0.36, 0.27); II 1.65 (0.45, 0.16, 0.45, 0.34, 0.26); III 1.45 (0.39. 0.13, 0.38, 0.31, 0.23); IV 1.95 (0.54, 0.16, 0.54, 0.43, 0.28). Genitalia. Internal genitalia with afferent spermathecae short, not extending past the sides of the abdomen ( Fig. 41B ); spermathecae tubular like ( Fig. 41A ).

Distribution. Known only from the type locality.
