Leptonetela zuojiashanensis Yao & Liu sp. nov.

Figs 7, 8M-P Vernacular name: 左家山小弱蛛

Material examined.

Holotype: ♂, China: Jiangxi Province, Yichun City, Wanzai County, Luocheng Town, Jiulongshan Forest Park, Zuojiashan Village, 28°21'07.52"N, 114°30'27.58"E, 164 m, 6.II.2021, K. Liu, D. Zhao, Z. Meng, Z. He & W. Li leg. (Lep-4).

Diagnosis.

The male of this species is similar to that of Leptonetela gubin Wang & Li, 2017 (in Wang et al. 2017: 386, fig. 48B-D) in having the curved cymbium forming an angle of ca 100° with tibial axis and the horn-like prolateral sclerite, but can be separated from it by the tibia having two spines including one very thick and strong spine proximally (vs a row of spines and lacking a thick and strong spine) (Figs 7B-D, 8M-P). It also resembles that of L. mengzongensis Wang & Li, 2011 (Wang and Li 2011: 10, fig. 24B-D) in having the horn-like prolateral sclerite, but can be easily distinguished from it by the tibia with a thick and strong proximal spine (vs slender) (Figs 7B-D, 8M, N).
