Falcileptoneta naejangsan sp. nov. Figures 3 View Figure 3 , 4 View Figure 4 , 12 View Figure 12

Type material.

Holotype. Male (NIBR), South Korea, Jeollabuk-do, Jeongeup-si, Naejang-dong, Mt. Naejangsan National Park (35.491727°N, 126.900469°E, elevation ca 237 m), 9 August 2019, ZG. Chen, Z. Zhao & YY. Hu leg. Paratype. 1 female (NIBR), same data as holotype.

Diagnosis.

Falcileptoneta naejangsan sp. nov. is similar to F. naejangensis Seo, 2015 and F. sunchangensis Seo, 2016 but can be distinguished by the shape of the two palpal tibial retrolaterodistal apophyses, with the dorsal apophysis beak-like and the ventral apophysis spine-like (Fig. 3D View Figure 3 ) (vs. dorsal one curved and ventral one triangular, and with one spine in F. naejangensis ; dorsal apophysis thick and spur-like, and ventral apophysis spine-like in F. sunchangensis ); and by the male palpal bulb with a spine-like prolateral sclerite and narrow leaf-like median sclerite (Fig. 3B-D View Figure 3 ) (vs. needle-shaped prolateral sclerite and longish, shoehorn-like median sclerite in F. naejangensis ; narrow, leaf-like prolateral sclerite and leaf-like median sclerite in F. sunchangensis ).

Description.

Male (holotype). Total length 1.68. Prosoma 0.69 long, 0.58 wide. Opisthosoma 0.99 long, 0.58 wide. Clypeus 0.10 high. Leg measurements: I 4.43 (1.15, 0.32, 1.22, 1.03, 0.71); II 3.41 (0.90, 0.26, 0.90, 0.77, 0.58); III 2.76 (0.83, 0.26, 0.65, 0.64, 0.38); IV 3.97 (1.15, 0.26, 1.15, 0.83, 0.58). Habitus as in Fig. 3A View Figure 3 . Prosoma dark brown. Eyes six (Fig. 3A View Figure 3 ). Median groove, cervical grooves and radial furrows distinct. Opisthosoma dark brown, ovoid. Palp (Fig. 3C, D View Figure 3 ): femur lacking strong spine; tibia with two retrolaterodistal apophyses, dorsal apophysis beak-like and ventral apophysis spine-like (Fig. 3D View Figure 3 ); tarsus with transverse depression (Fig. 3D View Figure 3 ). Bulb with embolus bearing sickle-like tip and three types of sclerites: prolateral sclerite spine-like; median sclerite narrow, leaf-like; retrolateral sclerite transparent and membranous (Fig. 3B-D View Figure 3 ).

Female (paratype). Similar to male in color and general features, habitus as in Fig. 4A, B View Figure 4 . Total length 1.80. Prosoma 0.68 long, 0.61 wide. Opisthosoma 1.12 long, 0.63 wide. Clypeus 0.11 high. Leg measurements: I 4.16 (1.15, 0.38, 1.15, 0.90, 0.58); II 3.15 (0.90, 0.26, 0.83, 0.71, 0.45); III 2.68 (0.77, 0.19, 0.64, 0.63, 0.45); IV 3.78 (1.15, 0.26, 1.09, 0.77, 0.51). Internal genitalia (Fig. 4C View Figure 4 ) with atrium rectangular, genital duct coiled apically, and spermathecae round.
