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

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 GoogleMaps .

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 View Figure 55 ) and the females by the posteriorly directed, coiled afferent spermathecae ( Fig. 6B View Figure 6 ). 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 View Figure 6 ); 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 View Figure 55 ). Eyes: six contiguous eyes surrounded by black pigmentation; PME smallest, ALE largest ( Fig. 6C View Figure 6 ). 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 View Figure 5 ). Palpal femur long; palpal tibia as long as cymbium ( Figs 5A–B View Figure 5 ). 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 View Figure 5 ).

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 View Figure 6 ) 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 View Figure 6 ); spermathecae oval ( Fig. 6A View Figure 6 ).
