Treatment

Speocera nuichua Li & Li View in CoL sp. nov. ( Figs 36–37 View Figure 36 View Figure 37 , 56H View Figure 56 )

Material examined. Holotype ♂ ( IZCAS), Vietnam, Ninh Thuan Province, Nui Chua National Park (11º43.565′N, 109º11.135′E), elev. 70 m, 30.VIII.2015, Leg. Q. Zhao, Y. Li & Z. Chen. Paratypes 1♂ 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. apo Deeleman-Reinhold, 1995 , but males can be distinguished by the palpal tibia which is shorter than the cymbium ( Figs 36A–B View Figure 36 ) and the chelicerae which are laterally excavated, with several short, strong setae ( Fig. 56H View Figure 56 ) and females by the very large, balloon-shaped spermathecae ( Fig. 37A View Figure 37 ). S. apo males have the palpal tibia longer than the cymbium, the chelicerae laterally straight, without special setae, and the females have oval spermathecae (Deeleman-Reinhold, 1995: figs 220–224).

Description. Male. Total length 0.93; carapace length 0.47; carapace width 0.38; abdomen length 0.44; abdomen width 0.37. Prosoma: carapace pyriform, narrowing gradually anteriorly; light yellow, suffused with a purplish pattern ( Fig. 37C View Figure 37 ); 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, laterally excavated, with several short, strong setae; promargin with a series of six teeth reaching the lamina; retromargin with two very small denticles ( Fig. 56H View Figure 56 ). Eyes: six contiguous eyes surrounded by black pigmentation; PME and ALE subequal, PLE largest ( Fig. 37C View Figure 37 ). Opisthosoma oval; purplish. Legs missing. Genitalia ( Fig. 36 View Figure 36 ). Palpal femur long; palpal tibia about 0.7 times as long as cymbium ( Figs 36A–B View Figure 36 ). Cymbium conical, without prolateral extensions. Bulb spherical. Embolus short, dark and basally without distinct associated sclerites; sperm duct very wide, narrowing distally ( Fig. 36D View Figure 36 ).

Female. Total length 1.03; carapace length 0.46; carapace width 0.41; abdomen length 0.55; abdomen width 0.48. Similar to male in color and general features ( Figs 37D–E View Figure 37 ) but larger. Chelicerae unmodified. Legs light yellow; leg formula 4123; leg lengths I 1.78 (0.48, 0.15, 0.53, 0.36, 0.26); II 1.58 (0.45, 0.14, 0.44, 0.32, 0.23); III 1.39 (0.38, 0.11, 0.36, 0.31, 0.23); IV 1.93 (0.54, 0.14, 0.56, 0.42, 0.28). Genitalia. Internal genitalia with afferent spermathecae very short, not extending past the sides of the abdomen ( Fig. 37B View Figure 37 ); spermathecae very large, balloon shaped ( Fig. 37A View Figure 37 ).

Distribution. Known only from the type locality.
