Four new species of the genus Falcileptoneta (Araneae, Leptonetidae) from Korea

The spider family Leptonetidae is tiny (1.0­3.0 mm), relatively primitive haplogyne, and characterized by the six­eyed pattern and generally live in caves or in leaf litter (Song et al., 1999). Leptonetids include 23 genera and 280 species, and are broadly distributed in the Hol­ arctic region (World Spider Catalog, 2016). The genus Longileptoneta was established by Seo (2015) for a new species, L. songniensis Seo, 2015, from Korea, and can be easily recognized by the strong spines restricted to the male palpal femur, the prolateral distal spur and the prolateral curvature of the palpal tarsus. Four additional new species, L. gachangensis, L. gayaensis, L. jangseongensis, and L. weolakensis, among the specimens collected during the Korean indi­ genous species survey were identified, and are described with the illustrations.
