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.
