In 2007, the junior author and his colleagues investigated termitophilous insects
in Khao Yai National Park, and they found several new species of termitophiles. Two
of them are described new species of staphylinid beetles, one in the genus Discoxenus
(Wasmann, 1904) belonging to the tribe Aleocharini and one in Odontoxenus Kistner,
1958 belonging to the tribe Pygostenini. All the specimens were found in fungus
gardens of Odontotermes termites; both genera have not been previously known from
Th ailand.
