Speocera heilan Li & Li View in CoL sp. nov. ( Figs 25–26 View Figure 25 View Figure 26 , 56C View Figure 56 )

Material examined. Holotype ♂ ( IZCAS), China, Hainan Province, Baisha County, Laoyuanmen Town , Heilan Village , sifting leaf litter in bamboo forest, 1.VII.2014 (19º6.672′N, 109º32.889′E), elev. 291 m, leg. F. Li & X. Wang. Paratypes 1♂ 3♀ ( IZCAS), same data as holotype GoogleMaps .

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

Diagnosis. Males of the new species are similar to S. ballarini Li & Li sp. nov. but can be distinguished by the laterally strongly excavated chelicerae ( Fig. 56C View Figure 56 ) and the very small embolus ( Fig. 25A View Figure 25 ). S. ballarini males have unmodified chelicerae ( Fig. 55D View Figure 55 ) and a long, ribbon-like embolus ( Fig. 8A View Figure 8 ). Females of the new species are similar to S. huifengi Li & Li sp. nov. but can be distinguished by the very small oval spermathecae ( Fig. 26A View Figure 26 ).

Description. Male. Total length 1.08; carapace length 0.51; carapace width 0.45; abdomen length 0.51; abdomen width 0.36. Prosoma: carapace pyriform, narrowing gradually anteriorly; yellow, suffused with purplish pattern ( Fig. 26C View Figure 26 ); 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, strongly excavated laterally; promargin with a series of six teeth reaching the lamina; retromargin with two very small denticles ( Fig. 56C View Figure 56 ). Eyes: six contiguous eyes surrounded by black pigmentation, PME smallest, PLE largest ( Fig. 26C View Figure 26 ). Opisthosoma oval; purplish. Legs light yellow; leg formula 4123; leg lengths I 2.00 (0.59, 0.16, 0.56, 0.40, 0.28); II 1.83 (0.53, 0.14, 0.53, 0.35, 0.28); III 1.64 (0.46, 0.15, 0.43, 0.34, 0.27); IV 2.13 (0.61, 0.15, 0.61, 0.46, 0.30). Genitalia ( Fig. 25 View Figure 25 ). Palpal femur long; palpal tibia and cymbium incrassate, palpal tibia strongly enlarged basally, about 1.1 times as long as cymbium ( Figs 25A–B View Figure 25 ). Cymbium conical, with a large prolateral extension basally. Bulb spherical, wider than high. Embolus small, dark, associated sclerites absent; sperm duct initially wide, gradually narrowing distally ( Fig. 25D View Figure 25 ).

Female. Total length 0.98; carapace length 0.51; carapace width 0.44; abdomen length 0.45; abdomen width 0.36. Similar to male in color and general features ( Figs 26D–E View Figure 26 ). Chelicerae unmodified. Leg lengths I 1.76 (0.38, 0.16, 0.56, 0.38, 0.27); II missing; III 1.52 (0.42, 0.14, 0.38, 0.32, 0.25); IV 2.08 (0.59, 0.16, 0.58, 0.43, 0.33). Genitalia. Internal genitalia with afferent spermathecae short, curved, not extending past the sides of the abdomen ( Fig. 26B View Figure 26 ); spermathecae oval ( Fig. 26A View Figure 26 ).
