Treatment

Speocera lahrak Li & Li View in CoL sp. nov. ( Figs 29–30 View Figure 29 View Figure 30 , 56D View Figure 56 )

Material examined. Holotype ♂ ( 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 & Z. Chen. Paratype 1♀ ( 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. stellafera Deeleman-Reinhold, 1995 , but males can be distinguished by the unmodified chelicerae ( Fig. 56D View Figure 56 ) and having the palpal tibia distinctly shorter than cymbium ( Figs 29A–B View Figure 29 ), and the females by the short, straight afferent spermathecae. S. stellafera 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 View Figure 30 ); 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 View Figure 56 ). Eyes: six contiguous eyes surrounded by black pigmentation, nearly subequal ( Fig. 30C View Figure 30 ). 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 View Figure 29 ). Palpal femur long; palpal tibia about 0.8 times as long as cymbium ( Figs 29A–B View Figure 29 ). 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 View Figure 29 ).

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 View Figure 30 ). 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 View Figure 30 ); spermathecae large, elongated oval ( Fig. 30A View Figure 30 ).

Distribution. Known only from the type locality.
