Revision of the Perinthina of the Australian and Oriental faunal regions (Coleoptera : Staphylinidae, Aleocharinae)

The Australian and Oriental termitophiles belonging to the subtribe Perinth ina (Tribe Termitonannini) are all redescribed and the generic concepts are redefined. The previously known genera that are revised are Lauella, Paral avella, and Eutermitophila, A new genus, Alzada is described from the Fiji Islands; type species, A. pulcherrima new species, from Taveuini Island. Wh ile no new species of Lauella are described, 5 species formerly in Lauella are transferred to Eutermitophila. These are E, aenigma, E. alomai E. javan a, E. lengkongensis, and E. palauensis. Four new species of Eutermitophila are described: E. borealis, from Australia, Northern Territory and North Qu eensland, with Nasutitermes longipennis; E. oshimaiensis from Indonesia, Su lawesi with N. oshimai; E, philippinensis from the Philippines, Luzon with N. balintauacensis; and E. torresiensis from Australia, North Queensland, w ith N. torresi. The phylogeny of the group of genera is briefly discussed. Some behavioral notes are presented especially for Eutermitophila lengkonge nsis, Lauella vitiensis and Alzada pulcherrima which show that while Euterm itophila are adapted to the nest and to a limited degree to the social syst em of the termites, Alzada and Lauella are more fully integrated into the s ocial life of the termites.
