Type material.

Holotype. Male (NIBR), South Korea, Jeollabuk-do, Buan-gun, Sangseo-myeon, Cheongrim-ri, Byeonsanbando National Park (35.670146°N, 126.629253°E, elevation ca 135 m), 8 August 2019, ZG. Chen, Z. Zhao & YY. Hu leg. Paratypes. 1 male and 1 female (NIBR), same data as holotype.

Diagnosis.

Longileptoneta byeonsanbando sp. nov. is similar to L. gayaensis Seo, 2016 and L. jangseongensis Seo, 2016 but can be distinguished by the palpal tibia with one distal columnar apophysis, with apophysis tip armed with one long spine retrolaterally (Figs 7D , 8B ) (vs. tibia without apophysis in L. gayaensis ; tibia with one small apophysis armed with one spine in L. jangseongensis ); by the palpal bulb with narrow, leaf-like prolateral sclerite and ribbon-like median sclerite (Fig. 7B-D ) (vs. needle-like prolateral sclerite and shoehorn-like median sclerite in L. gayaensis ; without prolateral sclerite and leaf-like median sclerite in L. jangseongensis ); and can be further distinguished from L. gayaensis by the presence of two spurs at tarsal tip (Fig. 8A, B ) (vs. one spur in L. gayaensis ).

Description.

Male (holotype). Total length 2.39. Prosoma 0.98 long, 0.86 wide. Opisthosoma 1.41 long, 0.90 wide. Clypeus 0.13 high. Leg measurements: I 6.81 (1.79, 0.33, 1.99, 1.67, 1.03); II 5.51 (1.56, 0.32, 1.54, 1.26, 0.83); III 4.43 (1.29, 0.26, 1.15, 1.02, 0.71); IV 6.15 (1.67, 0.32, 1.78, 1.47, 0.91). Habitus as in Fig. 7A . Prosoma brown. Eyes six (Fig. 7A ). Median groove, cervical grooves and radial furrows distinct. Opisthosoma brown, ovoid. Palp (Figs 7C, D , 8A, B ): femur with many strong spines and very long (Fig. 8A, B ); patella very long (Fig. 8A, B ); tibia with one distal columnar apophysis, with apophysis tip armed with one long spine retrolaterally (Figs 7D , 8B ); tarsus with two spurs at tip and many spines, and with prolateral curvature (Fig. 8A, B ). Bulb with leaf-like embolus and three types of sclerites: prolateral sclerite narrow, leaf-like; median sclerite ribbon-like; retrolateral sclerite with serrated tip, transparent and tongue-like (Fig. 7B-D ).

Female (one of the paratypes). Similar to male in color and general features, habitus as in Fig. 9A, B . Total length 2.02. Prosoma 0.78 long, 0.68 wide. Opisthosoma 1.24 long, 0.86 wide. Clypeus 0.12 high. Leg measurements: I 5.23 (1.41, 0.31, 1.47, 1.14, 0.90); II 4.13 (1.16, 0.21, 1.15, 0.90, 0.71); III 3.33 (0.96, 0.19, 0.83, 0.77, 0.58); IV 4.61 (1.28, 0.32, 1.27, 1.03, 0.71). Internal genitalia (Fig. 9C ): atrium trapezoidal, spermathecae and genital duct slender, tube-shaped, loosely coiled.

Etymology.

The specific name refers to the type locality and is a noun in apposition.

Habitat.

Litter layers in mixed forest.

Distribution.

South Korea (Jeollabuk-do; Fig. 12 ).
