Figs 22 View Figure 22 , 23 View Figure 23 , 24 View Figure 24 , 28F Vernacular name: 天门山长弱蛛 View Figure 28

Material examined.

Holotype: ♂, China: Fujian Province, Fuzhou City, Yongtai County, Geling Town , Yangxi Village , Tianmen Mountain , 25°49'5.34"N, 119°00'40.79"E, 10.IV.2023, J. Gong, R. Zhao & M. Wu leg. (Lep-11) GoogleMaps . Paratype: 2 ♀, 14.X.2023, Y. Yao & M. Wu leg, other data as same as the holotype (Lep-11).

Diagnosis.

The male of this species is similar to that of L. huboliao sp. nov. in having the femur with three rows of strong spines, one columnar tibial apophysis, armed with a short spine-like tip on palp and a needle-like prolateral sclerite, but can be easily distinguished from it by the rod-like median apophysis (vs lacking) the membranous conductor lacking a serrulate tip (vs present) (Figs 22C-G View Figure 22 , 23 View Figure 23 ). The female resembles L. huboliao sp. nov. in having a bell-like atrium and the spermathecal stalk lacking a spiral twist, but can be separated by the oval spermathecae (vs tube-shaped) (Fig. 24C View Figure 24 ).
