Longileptoneta tianmenensis Yao & Liu sp. nov.

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

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) . 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, 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).
