description: <i>Speocera lahrak</i> Li &amp; Li sp. nov. (Figs 29–30, 56D) Material examined. Holotype &amp;male; (IZCAS), Thailand, Nakhon Nayok Province, Mueang Nakhon Nayok District, forest near Lah Rak waterfall (14º17.472′N, 101º14.888′E), elev. 82 m, 3.XI.2014, leg. H. Zhao, Y. Li &amp; Z. Chen. Paratype 1&amp;female; (IZCAS), same data as holotype. Etymology. The specific name is derived from the type locality; noun. Diagnosis. The new species is similar to <i>S. stellafera</i> Deeleman-Reinhold, 1995, but males can be distinguished by the unmodified chelicerae (Fig. 56D) and having the palpal tibia distinctly shorter than cymbium (Figs 29A–B), and the females by the short, straight afferent spermathecae. <i>S. stellafera</i> males have laterally excavated chelicerae, the palpal tibia longer than the cymbium, and the females have very long, curved afferent spermathecae (Deeleman-Reinhold, 1995: figs 264–269). Description. Male. Total length 0.93; carapace length 0.46; carapace width 0.38; abdomen length 0.48; abdomen width 0.34. Prosoma: carapace pyriform, narrowing gradually anteriorly; light yellow, suffused with purplish pattern (Fig. 30C); pars cephalica flat; fovea not visible. Sternum light yellow, suffused with purplish color, longer than wide. Endites light yellow suffused with purplish tinge; with serrula; labium light yellow suffused with purplish tinge. Clypeus nearly vertical; short. Chelicerae light yellow; promargin with a series of six teeth reaching the lamina; retromargin with two small denticles (Fig. 56D). Eyes: six contiguous eyes surrounded by black pigmentation, nearly subequal (Fig. 30C). Opisthosoma oval; purplish. Legs light yellow; leg lengths I missing; II missing; III 1.38 (0.39, 0.13, 0.36, 0.28, 0.22); IV 1.91 (0.53, 0.13, 0.55, 0.42, 0.28). Genitalia (Fig. 29). Palpal femur long; palpal tibia about 0.8 times as long as cymbium (Figs 29A–B). Cymbium conical, without prolateral extension. Bulb spherical. Embolus ribbon-like, dark and basally with an associated plate-like sclerite; sperm duct initially wide, gradually narrowing distally (Fig. 29D). Female. Total length 0.90; carapace length 0.47; carapace width 0.38; abdomen length 0.42; abdomen width 0.31. Similar to male in color and general features (Figs 30D–E). Leg lengths I missing; II missing; III 1.34 (0.37, 0.13, 0.34, 0.28, 0.22); IV 1.80 (0.50, 0.14, 0.51, 0.39, 0.27). Genitalia. Internal genitalia with afferent spermathecae short, straight, not extending past the sides of the abdomen (Fig. 30B); spermathecae large, elongated oval (Fig. 30A). Distribution. Known only from the type locality.
