description: <i>Speocera longyan</i> Li &amp; Li sp. nov. (Figs 31–32, 56G) Material examined. Holotype &amp;male; (IZCAS), China, Guangxi Zhuang Autonomous Region, Hechi City, Du’an County, Xia’ao Town, Longyan Cave, 15.III.2015 (24º4.402′N, 108º3.257′E), elev. 173 m, leg. Z. Chen &amp; Y. Li. Paratypes 2&amp;male; 3&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. bachma</i> Li &amp; Li <b>sp. nov.</b>, but males can be distinguished by the laterally strongly curved chelicerae (Fig. 56G) and the asymmetrical male palpal bulb (Figs 31A–B), and females by the tubular spermathecae (Fig. 32A). <i>S. bachma</i> males have unmodified chelicerae (Fig. 55C), a symmetrical male palpal bulb (Figs 5A–B), and females have oval spermathecae (Fig. 6A). Description. Male. Total length 1.05; carapace length 0.51; carapace width 0.41; abdomen length 0.62; abdomen width 0.42. Prosoma: carapace pyriform, narrowing gradually anteriorly; shiny, light yellow, suffused with purplish pattern (Fig. 32A); 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, lateral margin strongly curved; promargin with a series of six teeth reaching the lamina; retromargin with two small denticles (Fig. 56G). Eyes: six contiguous eyes surrounded by black pigmentation; PME smallest, ALE largest (Fig. 32C). Opisthosoma oval; purplish. Legs light yellow; leg formula 4123; leg lengths I 1.97 (0.56, 0.18, 0.56, 0.38, 0.29); II 1.80 (0.51, 0.16, 0.51, 0.35, 0.28); III 1.60 (0.45. 0.14, 0.41, 0.34, 0.26); IV 2.18 (0.63, 0.16, 0.61, 0.45, 0.33). Genitalia (Fig. 31). Palpal femur long; palpal tibia as long as cymbium (Figs 31A–B). Cymbium conical, without prolateral extension. Bulb asymmetrical, elliptical, with a small apophysis distally. Embolus short, butterfly-like and without distinct associated sclerites; sperm duct initially wide, gradually narrowing distally (Fig. 31D). Female. Total length 1.14; carapace length 0.52; carapace width 0.43; abdomen length 0.62; abdomen width 0.49. Similar to male in color and general features (Figs 32D–E) but larger. Chelicerae unmodified. Leg formula 4123; leg lengths I 1.99 (0.58, 0.16, 0.58, 0.38, 0.29); II 1.82 (0.52, 0.16, 0.50, 0.34, 0.29); III 1.70 (0.47. 0.16, 0.45, 0.36, 0.27); IV 2.18 (0.61, 0.16, 0.64, 0.46, 0.33). Genitalia. Internal genitalia with afferent spermathecae short, strongly curved posteriorly from the epigastric furrow, not extending past the sides of the abdomen (Fig. 32B); spermathecae tubular shaped (Fig. 32A). Distribution. Known only from the type locality.
