Speocera gexuejuni Li & Li View in CoL sp. nov. ( Figs 22–23 View Figure 22 View Figure 23 , 56B View Figure 56 )

Material examined. Holotype ♂ ( IZCAS), China, Hainan Province, Lingshui County, Benhao Town , Diaoluoshan Mountain Natural Reserve , riverside, near ticket lobby (18º40.132′N, 109º53.911′E), elev. 280 m, 24.VI.2014, leg.

Etymology. The specific name is named in honor of Prof. Dr. Ge Xuejun from South China Botanical Garden, Chinese Academy of Sciences, for his contribution in plant systematics and evolution; name in genitive case.

Diagnosis. The new species is very similar to S. heilan Li & Li sp. nov. but can be distinguished by the spherical male palpal bulb and the belt-like embolus ( Fig. 22 View Figure 22 ). S. heilan has a more flattened palpal bulb and a very small embolus ( Fig. 25 View Figure 25 ).

Description. Male. Total length 1.08; carapace length 0.53; carapace width 0.45; abdomen length 0.49; abdomen width 0.34. Prosoma: carapace pyriform, narrowing gradually anteriorly, anterior margin straight in dorsal view; light yellow, suffused with purplish pattern ( Fig. 23C View Figure 23 ); 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; external margin strongly excavated; promargin with a series of six teeth reaching the lamina; retromargin with two very small denticles ( Fig. 56B View Figure 56 ). Eyes: six contiguous eyes surrounded by black pigmentation, ALE and PME subequal, PLE largest ( Fig. 23C View Figure 23 ). Opisthosoma oval; purplish. Legs light yellow; leg lengths I, II missing; III 2.12 (0.94, 0.14, 0.45, 0.34, 0.25); IV 2.20 (0.61, 0.16, 0.64, 0.45, 0.34). Genitalia ( Fig. 22 View Figure 22 ). Palpal femur long; palpal tibia and cymbium incrassate, palpal tibia strongly enlarged basally, 1.1 times as long as cymbium ( Figs 22A–B View Figure 22 ). Cymbium conical, with prolateral extension basally. Bulb spherical, as long as wide. Embolus beltlike, dark, associated sclerites short; sperm duct initially wide, gradually narrowing distally ( Fig. 22D View Figure 22 ).

Female. Total length 1.02; carapace length 0.55; carapace width 0.43; abdomen length 0.59; abdomen width 0.42. Similar to male in color and general features ( Figs 23D–E View Figure 23 ). Chelicerae unmodified. Leg lengths I 1.96 (0.55, 0.19, 0.56, 0.38, 0.28); II 1.73 (0.50, 0.16, 0.48, 0.34, 0.27); III 1.54 (0.45, 0.14, 0.38, 0.33, 0.24); IV 2.02 (0.58, 0.16, 0.56, 0.45, 0.28). Genitalia. Internal genitalia with afferent spermathecae short, tip slightly curved posteriorly, not extending past the sides of the abdomen ( Fig. 23B View Figure 23 ); spermathecae oval ( Fig. 23A View Figure 23 ).
