Figs 11 , 12 , 13 , 28B Vernacular name: 虎伯寮长弱蛛 Material examined. Holotype : ♂ , China : Fujian Province , Zhangzhou City , Nanjing County , Huboliao Nature Reserve , Huboliao area , 24°31'2.88"N , 117°14'53.47"E , 08.XI.2023 , Y. Yao , J. Gong , R. Zhao & M. Wu leg. (Lep-15) . Paratype : 1 ♀ , the same data as the holotype (Lep-15) ; 1 ♂ , 24°31'20.98"N , 117°17'32.01"E , 09.XI.2023 , Y. Yao, J. Gong, R. Zhao & M. Wu leg. (Lep-15). Diagnosis. The male of this species is similar to that of Longileptoneta shenxian Wang & Li, 2020 (in Wang et al. 2020 : 698, fig. 12A-D) in having the bulb with an extruded coniform anterior part and three rows of spines, but can be distinguished from it by the carapace with six eyes (vs absent), the tibia with one long columnar apophysis armed with a long spine (vs one short columnar apophysis, armed with one long, curved spine) and the long needle-like prolateral sclerite (vs thick) (Figs 11 , 12 ). The female can be easily separated from L. shenxian ( Wang et al. 2020 : 698, fig. 13C) by the bell-shaped atrium, but can be separated by the carapace with six eyes (vs absent) and the distal spermathecal stalk lacking a coil (vs present) (Fig. 13 ).

Known only from the type locality in Fujian Province, China (Fig. 29 ). Etymology. The name is taken from the type locality, noun in apposition.
