Type material.

Holotype. Male (NIBR), South Korea, Gyeongsangnam-do, Hadong-gun, Hwagye-myeon, Daeseong-ri, Mt. Jirisan National Park (35.273974°N, 127.657439°E, elevation ca 357 m), 15 August 2019, ZG. Chen, Z. Zhao & YY. Hu leg. Paratype. 1 female (NIBR), same data as holotype.

Diagnosis.

Longileptoneta jirisan sp. nov. is similar to L. gachangensis Seo, 2016 and L. weolakensis Seo, 2016 but can be distinguished by the palpal tibia with one retrolaterodistal spur (Fig. 10D) (vs. tibia without apophysis in L. gachangensis and L. weolakensis); and by the palpal bulb with spur-like prolateral sclerite and tongue-like retrolateral sclerite (Fig. 10C, D) (vs. blade-like prolateral sclerite and skinny and triangular retrolateral sclerite in L. gachangensis; without prolateral sclerite and triangular retrolateral sclerite in L. weolakensis).
