Material examined.

Holotype: ♂, China: Jiangxi Province, Ji’an City, Qingyuan District, Donggu Town , Dawu Mountain , 26°40'48.69"N, 115°25'07.79"E, 1031 m, 25.X.2020, K. Liu, Y. Ying & S. Yuan leg. (Lep-8) GoogleMaps . Paratype: 7 ♂, 2 ♀, the same data as the holotype (Lep-8) GoogleMaps .

Diagnosis.

The male of this species is similar to Leptonetela sexdentata Wang & Li, 2011 (see Wang and Li 2011: 15, figs 53A-D) in having a tongue-shaped prolateral lobe, but can be distinguished from it by dorsal habitus with obvious black-brown stripes (vs pale in L. sexdentata ) and the foot-shaped median apophysis (vs square-shaped) (Figs 3 View Figure 3 , 8A-D View Figure 8 ). Females resemble that of Leptonetela rudong Wang & Li, 2017 (see Wang et al. 2017: 362, fig. 31C) in having a sub-rectangular atrium, but can be separated from it by the spermathecal stalk with seven spirals (vs six) and the slightly curved spermathecae (vs straight) (Fig. 4C View Figure 4 ).
