Longileptoneta renzhouensis Yao & Liu sp. nov.

Figs 19, 20, 21, 28E Vernacular name: 仁洲长弱蛛

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) . Paratype: 2 ♂, 2 ♀, the same data as the holotype (Lep-14); 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, 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).
