Genus Batraxis Reitter, 1881

This is a diverse group comprising 65 species distributed mainly in the Oriental-Australian Region, with a few species reaching the eastern and southern Palaearctic Realm, and one (i.e., B. hampei Reitter, 1881, type species of the genus) occurring in Greece (WANG et al. 2016; WANG & YIN 2016a, b; LÖBL 2017). Members have been commonly encountered in sifted samples of leaf litter or associated with decomposing logs, while two species from Japan were postulated to be inquilines of Lasius Fabricius, 1804 ants (NOMURA 1986, MARUYAMA 2004). Here the first cavernicolous species of Batraxis is described.
