Speocera payakumbuh Li & Li View in CoL sp. nov. ( Figs 38–39 View Figure 38 View Figure 39 , 57A View Figure 57 )

Material examined. Holotype ♂ ( IZCAS), Indonesia, Sumatra, West Sumatra Province, Payakumbuh, near exit of Ngalau Indah Cave (0º15.296′S, 100º36.256′E), elev. 626 m, 14.V.2014, leg. Z. Yao. 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. xuanson Li & Li sp. nov., but males can be distinguished by the unmodified chelicerae ( Fig. 57A View Figure 57 ) and the very long, curved associated sclerites of the male embolus ( Figs 38A–B View Figure 38 ), and females by the small spermathecae ( Fig. 39A View Figure 39 ). S. xuanson males have the chelicerae laterally strongly excavated, with a horn-like apophysis ( Figs 57I–J View Figure 57 ), and long, straight associated sclerites of the embolus ( Figs 51A–B View Figure 51 ), and the females have relatively larger spermathecae ( Fig. 52A View Figure 52 ).

Description. Male. Total length 0.79; carapace length 0.40; carapace width 0.34; abdomen length 0.38; abdomen width 0.30. Prosoma: carapace broadly oval, narrowing gradually anteriorly; shiny, light yellow, suffused with purplish pattern ( Fig. 39C View Figure 39 ); pars cephalica flat; fovea not visible. Sternum brown, 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. 57A View Figure 57 ). Eyes: six contiguous eyes surrounded by black pigmentation; PME, ALE and PLE nearly subequal ( Fig. 39C View Figure 39 ). Opisthosoma oval; purplish. Legs light yellow; leg lengths I, II, III missing; IV 1.65 (0.45, 0.14, 0.45, 0.37, 0.24). Genitalia ( Fig. 38 View Figure 38 ). Palpal femur long; palpal tibia twice as long as cymbium. Cymbium conical, with a large prolateral extension basally. Bulb spherical. Embolus triangular, dark and basally with one long, curved associated sclerite; sperm duct initially wide narrowing distally ( Fig. 38D View Figure 38 ).

Female. Total length 0.99; carapace length 0.42; carapace width 0.37; abdomen length 0.56; abdomen width 0.42. Similar to male in color and general features ( Figs 39D–E View Figure 39 ) but larger. Leg lengths I 1.51 (0.40, 0.14, 0.44, 0.30, 0.23); II missing; III 1.23 (0.32. 0.13, 0.31, 0.28, 0.20); IV 1.61 (0.45, 0.13, 0.44, 0.35, 0.25). Genitalia. Internal genitalia with afferent spermathecae long, extending past the sides of the abdomen ( Fig. 39B View Figure 39 ); spermathecae oval ( Fig. 39A View Figure 39 ).
