Type material.

Holotype: • ♂, China: Fujian Province, Fuzhou City, Jin’an District, Fuzhou National Forest Park , 26°10'14.13"N, 119°16'48.38"E, 26 April 2024, Y. Yao, J. Gong, M. Wu and R. Zhao leg. (Lep-24, ASM-JGSU) GoogleMaps . Paratype: • 1 ♀, other data as same as the holotype. (Lep-24, ASM-JGSU) GoogleMaps .

Diagnosis.

The male of this species is similar to that of Leptonetela yuanhaoi Yao & Liu, 2024 ( Liu et al. 2024: 293, figs 5 B-D, 8 E-L) in having the tibia with a row of spines retrolaterally including one thick strong spine proximally and several thin spines, the tongue-shaped prolateral lobe and the median apophysis with five teeth distally but can be separated from it by the median apophysis with broad base (vs narrow) and the prolateral one tooth very strong (vs small) (Fig. 1 C-I View Figure 1 ). The female can be easily distinguished from that of L. yuanhaoi ( Liu et al. 2024: 293, fig. 6 C) by the large subtriangular atrium (vs slightly small and sub-trapezoidal atrium) and ventrally extended spermathecal stalk (vs dorsally) with a small spermathecae (vs slightly enlarged) (Fig. 2 C View Figure 2 ). The female is also similar to that of L. flabellaris Wang & Li, 2011 ( Wang and Li 2011: 6, fig. 6 C) in having the large subtriangular atrium, it can be easily distinguished by the spermathecal stalk with four spirals (vs five) and spermathecae curves anteriorly (vs posteriorly) (Fig. 2 C View Figure 2 ).
