Falcileptoneta dolsan sp. nov. Figures 1 View Figure 1 , 2 View Figure 2 , 12 View Figure 12

Type material.

Holotype. Male (NIBR), South Korea, Jeollanam-do, Yeosu-si, Dolsan-eup, Seodeok-ri (34.641085°N, 127.760978°E, elevation ca 93 m), 13 August 2019, ZG. Chen, Z. Zhao & YY. Hu leg. Paratypes. 1 male and 1 female (NIBR), same data as holotype.

Diagnosis.

Falcileptoneta dolsan sp. nov. is similar to F. digitalis Seo, 2015 and F. geumsanensis Seo, 2016 but can be distinguished by the presence of three palpal tibial distal apophyses, dorsal apophysis sickle-shaped, middle apophysis black, triangular and ventral apophysis narrow and leaf-like (Fig. 1D View Figure 1 ) (vs. dorsal apophysis long and spur-like, middle apophysis black and rugulose, and ventral apophysis finger-like in F. digitalis ; dorsal apophysis beak-like, middle apophysis leaf-like and ventral apophysis spur-like in F. geumsanensis ); and by the bulb with a spine-like prolateral sclerite (Fig. 1C View Figure 1 ) (vs. narrow, leaf-like prolateral sclerite in F. digitalis and F. geumsanensis ).

Description.

Male (holotype). Total length 1.67. Prosoma 0.75 long, 0.62 wide. Opisthosoma 0.92 long, 0.66 wide. Clypeus 0.10 high. Leg measurements: I 4.39 (1.21, 0.24, 1.20, 1.03, 0.71); II 3.42 (0.90, 0.22, 0.89, 0.77, 0.64); III 2.84 (0.83, 0.22, 0.71, 0.70, 0.38); IV 4.05 (1.15, 0.24, 1.09, 0.93, 0.64). Habitus as in Fig. 1A View Figure 1 . Prosoma brown. Eyes six (Fig. 1A View Figure 1 ). Median groove, cervical grooves and radial furrows distinct. Opisthosoma brown, ovoid. Palp (Fig. 1C, D View Figure 1 ): femur without strong spine; tibia with three distal apophyses and one spine retrolaterally, dorsal apophysis sickle-shaped, middle apophysis black, triangular, ventral apophysis narrow, leaf-like (Fig. 1D View Figure 1 ), and with one strong dorsal spur (Fig. 1C, D View Figure 1 ); tarsus with transverse depression (Fig. 1D View Figure 1 ). Bulb with embolus bearing sickle-like tip and three types of sclerites: prolateral sclerite spine-like; median sclerite shoehorn-like; retrolateral sclerite transparent and membranous (Fig. 1B-D View Figure 1 ).

Female (paratype). Similar to male in color and general features, habitus as in Fig. 2A, B View Figure 2 . Total length 2.09. Prosoma 0.74 long, 0.62 wide. Opisthosoma 1.35 long, 1.06 wide. Clypeus 0.12 high. Leg measurements: I 3.89 (1.05, 0.25, 1.03, 0.92, 0.64); II 3.24 (0.89, 0.24, 0.86, 0.67, 0.58); III 2.81 (0.79, 0.23, 0.69, 0.64, 0.46); IV 3.72 (1.03, 0.24, 1.01, 0.85, 0.59). Internal genitalia (Fig. 2C View Figure 2 ) with atrium rectangular, genital duct coiled apically, and spermathecae pear-shaped.

Etymology.
