Speocera bukittinggi Li & Li sp. nov. ( Figs 14–15 , 55G )

Material examined. Holotype ♂ ( IZCAS), Indonesia, Sumatra, West Sumatra Province, Bukittinggi, near entrance of Tarang Cave (0º12.653′S, 100º24.977′E), elev. 877 m, 13.V.2014, leg. Z. Yao. Paratype 1♀ ( IZCAS), same data as holotype .

Etymology. The specific name is derived from the type locality; noun.

Diagnosis. The new species is similar to S. transleuser Deeleman-Reinhold, 1995 , but males can be distinguished by the pyriform shaped palpal bulb ( Figs 14A–B ), the long, dark embolus and plate-like associated sclerites ( Fig. 14D ) and the female by the strongly curved, long afferent spermathecae ( Fig. 15B ). S. transleuser males have a nearly flattened palpal bulb and a very small embolus, and females have slightly curved afferent spermathecae (Deeleman-Reinhold, 1995: figs 257–260).

Description. Male. Total length 0.89; carapace length 0.44; carapace width 0.37; abdomen length 0.45; abdomen width 0.38. Prosoma: carapace pyriform, narrowing gradually anteriorly; light yellow, strongly suffused with purplish pattern ( Fig. 15C ); 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. 55G ). Eyes: six contiguous eyes surrounded by black pigmentation; PME smallest, PLE largest ( Fig. 15C ). Opisthosoma oval; purplish. Legs light yellow; leg formula 4123; leg lengths I 1.56 (0.45, 0.11, 0.45, 0.31, 0.24); II 1.44 (0.42, 0.11, 0.40, 0.30, 0.22); III 1.27 (0.36, 0.13, 0.31, 0.28, 0.20); IV 1.67 (0.49, 0.12, 0.47, 0.38, 0.23). Genitalia ( Fig. 14 ). Palpal femur long; palpal tibia strongly elongated, about 2.5 times as long as cymbium ( Figs 14A–B ). Cymbium conical, without prolateral extension. Bulb pyriform, much longer than wide. Embolus long, dark and basally with associated platelike sclerites; sperm duct wide initially, gradually narrowing distally ( Fig. 14D ).

Female. Total length 0.92; carapace length 0.43; carapace width 0.38; abdomen length 0.47; abdomen width 0.42. Similar to male in color and general features ( Figs 15D–E ). Leg lengths I, II, IV missing; III 1.18 (0.31, 0.13, 0.30, 0.25, 0.20). Genitalia. Internal genitalia with afferent spermathecae long, curved, not extending past the sides of the abdomen ( Fig. 15B ); spermathecae large, amorphous ( Fig. 15A ).

Distribution. Known only from the type locality.
