Speocera yiduoi Lin & Li , sp. nov. ( Fig. 30 )

Etymology. The specific name is dedicated to Mr. Yiduo Wang (Zhuhai, China), who has helped us greatly with this research; noun (name) in genitive case.

Diagnosis. The new species is similar to S. ankalana Li & Li, 2019 , but males can be distinguished by having the embolus shorter than the associated sclerite (vs. longer than the associated sclerite in S. ankalana ).

Description. Male (holotype). Total length 1.01, carapace 0.61 long, 0.42 wide; opisthosoma 0.57 long, 0.33 wide. Chelicerae anterolateral margin with outgrowth, promargin with a series of 5 teeth. Leg measurements: I 1.94 (0.59, 0.69, 0.40, 0.26), II 1.76 (0.54, 0.63, 0.36, 0.23), III 1.58 (0.49, 0.52, 0.34, 0.23), IV 2.14 (0.63, 0.73, 0.47, 0.31).

Coloration. Carapace pyriform, narrowing gradually anteriorly; light yellow, suffused with purplish pattern; pars cephalica flat, fovea not visible. Sternum light yellow, suffused with purplish color, longer than wide. Endites light yellow, suffused with purplish tinge; labium light yellow, suffused with purplish tinge. Clypeus nearly vertical, short. Chelicerae light yellow. Eyes: 6 contiguous eyes surrounded by black pigmentation, PME smallest, PLE largest. Legs light yellow. Opisthosoma oval; purplish.

Palp ( Fig. 30 ). Femur almost as long as cymbium. Tibia shorter than cymbium. Cymbium conical, without prolateral extension. Bulb spherical. Embolus short, black, associated sclerite longer than embolus, tip blunt. Sperm duct gradually tapering distally.

Material examined. Holotype ♂ (IZCAS-Ar44823), China: Guangdong, Zhuhai City, Jiangjun Mountain (22.2326°N, 113.5666°E, elev. 1200 m), 4.IV.2022, Yiduo Wang leg.

Distribution. Known only from the type locality.
