Description

Speocera bachma Li & Li sp. nov. (Figs 5–6, 55C)

Material examined. Holotype ♂ (IZCAS), Vietnam, Thua Thien Hue Province, Bach Ma National Park, Da Dung Village (16º13.203′N, 107º52.944′E), elev. 69 m, 26.VIII.2015, leg. Q. Zhao, Y. Li & Z. Chen. Paratypes 2♂ 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. capra Deeleman-Reinhold, 1995, but males can be distinguished by the unmodified chelicerae (Fig. 55C) and the females by the posteriorly directed, coiled afferent spermathecae (Fig. 6B). S. capra males have laterally excavated chelicerae, with a lateral horn, and females have anteriorly directed, straight afferent spermathecae (Deeleman-Reinhold, 1995: figs 273–279).

Description. Male. Total length 0.92; carapace length 0.49; carapace width 0.41; abdomen length 0.46; abdomen width 0.33. Prosoma: carapace pyriform, narrowing gradually anteriorly; shiny, light yellow, suffused with purplish pattern (Fig. 6C); pars cephalica flat; fovea not visible. Sternum light yellow, suffused with purplish color, 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; promargin with a series of six teeth reaching the lamina; retromargin with two very small denticles (Fig. 55C). Eyes: six contiguous eyes surrounded by black pigmentation; PME smallest, ALE largest (Fig. 6C). Opisthosoma oval; purplish. Legs light yellow; leg lengths I 1.86 (0.53, 0.14, 0.55, 0.36, 0.28); II 1.71 (0.50, 0.14, 0.47, 0.33, 0.27); III missing; IV 1.93 (0.56, 0.15, 0.54, 0.42, 0.26). Genitalia (Fig. 5). Palpal femur long; palpal tibia as long as cymbium (Figs 5A–B). Cymbium conical, without prolateral extension. Bulb spherical. Embolus very short, dark and without distinct associated sclerites; sperm duct initially wide, gradually narrowing distally (Fig. 5D).

Female. Total length 1.06; carapace length 0.51; carapace width 0.42; abdomen length 0.54; abdomen width 0.46. Similar to male in color and general features (Figs 6D–E) but larger. Leg lengths I 1.81 (0.50, 0.14, 0.51, 0.38, 0.27); II 1.67 (0.48, 0.16, 0.46, 0.33, 0.25); III missing; IV 1.94 (0.55, 0.13, 0.56, 0.42, 0.28). Genitalia. Internal genitalia with afferent spermathecae short, strongly curved away from the epigastric furrow, not extending past the sides of the abdomen; tip of the afferent spermathecae question mark shaped (Fig. 6B); spermathecae oval (Fig. 6A).

Distribution. Known only from the type locality.
