Material examined.

Holotype: ♂, China: Fujian Province, Fuzhou City, Minhou County, Jingxi Town , Renzhou Village , Sandiejing Forest Park , 26°16'3.31"N, 119°09'5.08"E, 24.X.2023, Y. Yao, J. Gong, R. Zhao & M. Wu leg. (Lep-14) GoogleMaps . Paratype: 2 ♂, 2 ♀, the same data as the holotype (Lep-14) GoogleMaps ; 1 ♂, 29.X.2023, other data as same as the holotype (Lep-14).

Diagnosis.

The male of this species can be easily distinguished from other members of this genus by the very long curved spine-like prolateral sclerite with a feathery tip (Figs 19C-E View Figure 19 , 20 View Figure 20 ). The female resembles L. zhuxian Wang & Li, 2020 ( Wang et al. 2020: 700, fig. 16C) in having spheroid spermathecae and the subtrapezoid atrium, but can be separated by the slightly curved spermathecal stalk (vs waved) (Fig. 21C View Figure 21 ).

Palp (Figs 19C-E View Figure 19 , 20 View Figure 20 ). Femur with three rows of short strong spines ventrally, dorsally, and prolaterally; patella lacking spine; tibia with one columnar apophysis, armed with one straight spine, and one long and very thick spine, slightly shorter than the apophysis. Cymbium with a distinct constriction medially. Tip of bulb: one broad median apophysis, with a furcate tip, including one long membranous and one hook-shaped; prolateral lobe finger-like; conductor membranous, touching with prolateral sclerite; prolateral sclerite waved, needle-like, with a feathery tip.

Chelicerae (Fig. 21B View Figure 21 ) with nine promarginal and ten retromarginal teeth. Endites with several long spines anterolaterally. Sternum (Fig. 21B View Figure 21 ) shield-shaped, nearly as long as wide, with dense scale-like surface, lateral margin thickened, posterior end blunt.
