Differential diagnosis.
This new species is similar to F. yebongsanensis Kim, Lee & Namkung, 2004 and Leptoneta kwangreungensis Kim, Jung, Kim & Lee, 2004 but can be separated by one hook-like retrolateral apophysis on the palpal tibia, leaf-shaped median apophysis, and sickle-shaped embolus ( Figure 5C View Figure 5 ) (vs. short tubercle without spines or bristles on tibia, hook-shaped median apophysis and sickle-shaped embolus in F. yebongsanensis ; spine-shaped embolus and median apophysis in L. kwangreungensis ).
Description.
Male (holotype). Total length 1.58 ( Figure 5A View Figure 5 ). Carapace 0.64 long, 0.57 wide. Opisthosoma 0.94 long, 0.67 wide. Prosoma brown. Eyes six. Median groove, distinct cervical grooves and radial furrows. Opisthosoma brown, ovoid. Leg measurements: I 3.95 (1.09, 0.19, 1.19, 0.84, 0.64); II 3.06 (0.86, 0.18, 0.86, 0.64, 0.52); III 2.51 (0.71, 0.16, 0.67, 0.59, 0.38); IV 4.28 (1.12, 0.21, 1.29, 0.94, 0.72).

Embolus with a sickle-shaped tip and three types of sclerites: prolateral sclerite spine-like; median sclerite leaf-like; retrolateral sclerite membranous ( Figure 5B View Figure 5 ).
Female (one of the paratypes). Similar to male in color and general features. Total length 1.51 ( Figure 6A, B View Figure 6 ). Prosoma 0.63 long, 0.55 wide. Opisthosoma 0.88 long, 0.87 wide.
