Longileptoneta jiaxiani Yao & Liu sp. nov.

Figs 14, 15, 16, 28C Vernacular name: 嘉贤长弱蛛

Material examined.

Holotype: ♂, China: Fujian Province, Fuzhou City, Cangshan District, Jinshan campus in Fujian Agriculture and Forestry University, 26°2'21.12"N, 119°19'56.66"E, 29.IV.2023, Y. Yao, J. Gong & M. Wu leg. (Lep-10) . Paratype: 1 ♀, the same data as the holotype (Lep-10) .

Diagnosis.

The male of this species is similar to that of L. shenxian Wang & Li, 2020 (in Wang et al. 2020: 698, fig. 12A-D) in having the bulb with an extruded coniform anterior part and the spine-like prolateral sclerite, but can be distinguished from it by the carapace with six eyes (vs absent) and the patella with a very strong and thick spine (vs absent), and the hook-shaped embolus (vs the narrowed lamellar embolus) (Figs 14C-E, 15). The female resembles L. shenxian (Wang et al. 2020: 698, fig. 13A-C) in having a bell-shaped atrium, but can be separated by the carapace with eyes (vs lacking) and the C-shaped spermathecal stalk (vs S-shaped) (Fig. 16).

Cymbium with a distinct constriction medially. Tip of bulb: one spine-like prolateral sclerite; prolateral lobe lamellar; conductor membranous, with banded tip, slightly shorter than prolateral sclerite.
