Two new species of Aleocharinae (Coleoptera, Staphylinidae) found in fungus gardens of Odontotermes termites (Isoptera, Termitidae, Macrotermitinae) in Khao Yai National Park, Thailand

Abstract

Discoxenus katayamai sp. n. and Odontoxenus thailandicus sp. n. are described from Khao Yai National Park, East Th ailand. Both species were collected from nests of termite of the genus Odontotermes Holmgren, 1912. Th ese are the fi rst records of both genera from Th ailand. Discoxenus katayamai is similar to D. indicus Wasmann, 1904, and O. thailandicus is similar to O. butteri (Wasmann, 1916). Each species is easily distinguished from their congeners by the body size, the number of the setae on the pronotum, elytra and abdomen and other characters discussed below.
