Fu & K. Yang leg. Etymology. The specific name refers to the type locality and is a noun in apposition. Diagnosis. This new species is similar to Rhyssoleptoneta aosen (Zhu and Li 2021: figs 9 A – D, 10 A – C) in the scape of female genital area, but can be distinguished by the chelicerae with eight promarginal teeth and by the stridulatory file on the lateral margin (Fig. 13 D) vs. seven promarginal teeth and lacking the stridulatory file, palpal bulb with membranous median outgrowth, without tooth-shaped projections (Fig. 11 D, E) vs. without median outgrowth but with three tooth-shaped projections, and the short projection of the palpal tarsus distally (Fig. 11 E) vs. on the middle area.

Eye sizes and interdistances: ALE 0.06, PLE 0.06, PME 0.04; ALE – PME 0.06, PLE – PLE 0.06, PLE – PME 0.02; AER 0.10, PER 0.12. Carapace light yellow. Median groove, cervical grooves and radial furrows indistinct. Chelicerae with eight large promarginal and four small retromarginal teeth, with stridulatory file on the lateral margin.
