Longileptoneta buyongsan sp. nov. Figures 5, 6, 12

Type material.

Holotype. Male (NIBR), South Korea, Chungcheongbuk-do, Eumseong-gun, Eumseong-eup, Sajeong-ri, Mt. Buyongsan (36.970236°N, 127.619596°E, elevation ca 167 m), 6 August 2019, ZG. Chen, Z. Zhao & YY. Hu leg. Paratypes. 1 male and 1 female (NIBR), same data as holotype.

Diagnosis.

Longileptoneta buyongsan sp. nov. is similar to L. gayaensis Seo, 2016 and L. songniensis Seo, 2015 but can be distinguished by the palpal tibia with one small retrolaterodistal apophysis (Fig. 5D) (vs. tibia without apophysis in L. gayaensis and L. songniensis); by the palpal tarsus without spur at tip (Fig. 5C, D) (vs. tarsus with one spur at tip in L. gayaensis; tarsus with one spur at tip and one prolateroproximal spur, branched retrolaterally in L. songniensis); also distinguished from L. songniensis by the palpal bulb with needle-shaped prolateral sclerite and shoehorn-like median sclerite (Fig. 5B-D) (vs. without prolateral sclerite and finger-like median sclerite in L. songniensis).
