Treatment

Speocera longyan Li & Li View in CoL sp. nov. ( Figs 31–32 View Figure 31 View Figure 32 , 56G View Figure 56 )

Material examined. Holotype ♂ ( IZCAS), China, Guangxi Zhuang Autonomous Region , Hechi City , Du’an County, Xia’ao Town , Longyan Cave , 15.III.2015 (24º4.402′N, 108º3.257′E), elev. 173 m, leg. Z. Chen & Y. Li. 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. bachma Li & Li sp. nov., but males can be distinguished by the laterally strongly curved chelicerae ( Fig. 56G View Figure 56 ) and the asymmetrical male palpal bulb ( Figs 31A–B View Figure 31 ), and females by the tubular spermathecae ( Fig. 32A View Figure 32 ). S. bachma males have unmodified chelicerae ( Fig. 55C View Figure 55 ), a symmetrical male palpal bulb ( Figs 5A–B View Figure 5 ), and females have oval spermathecae ( Fig. 6A View Figure 6 ).

Description. Male. Total length 1.05; carapace length 0.51; carapace width 0.41; abdomen length 0.62; abdomen width 0.42. Prosoma: carapace pyriform, narrowing gradually anteriorly; shiny, light yellow, suffused with purplish pattern ( Fig. 32A View Figure 32 ); 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, lateral margin strongly curved; promargin with a series of six teeth reaching the lamina; retromargin with two small denticles ( Fig. 56G View Figure 56 ). Eyes: six contiguous eyes surrounded by black pigmentation; PME smallest, ALE largest ( Fig. 32C View Figure 32 ). Opisthosoma oval; purplish. Legs light yellow; leg formula 4123; leg lengths I 1.97 (0.56, 0.18, 0.56, 0.38, 0.29); II 1.80 (0.51, 0.16, 0.51, 0.35, 0.28); III 1.60 (0.45. 0.14, 0.41, 0.34, 0.26); IV 2.18 (0.63, 0.16, 0.61, 0.45, 0.33). Genitalia ( Fig. 31 View Figure 31 ). Palpal femur long; palpal tibia as long as cymbium ( Figs 31A–B View Figure 31 ). Cymbium conical, without prolateral extension. Bulb asymmetrical, elliptical, with a small apophysis distally. Embolus short, butterfly-like and without distinct associated sclerites; sperm duct initially wide, gradually narrowing distally ( Fig. 31D View Figure 31 ).

Female. Total length 1.14; carapace length 0.52; carapace width 0.43; abdomen length 0.62; abdomen width 0.49. Similar to male in color and general features ( Figs 32D–E View Figure 32 ) but larger. Chelicerae unmodified. Leg formula 4123; leg lengths I 1.99 (0.58, 0.16, 0.58, 0.38, 0.29); II 1.82 (0.52, 0.16, 0.50, 0.34, 0.29); III 1.70 (0.47. 0.16, 0.45, 0.36, 0.27); IV 2.18 (0.61, 0.16, 0.64, 0.46, 0.33). Genitalia. Internal genitalia with afferent spermathecae short, strongly curved posteriorly from the epigastric furrow, not extending past the sides of the abdomen ( Fig. 32B View Figure 32 ); spermathecae tubular shaped ( Fig. 32A View Figure 32 ).

Distribution. Known only from the type locality.
