Abstract
The osoriine beetles of New Zealand formerly placed in genus Holotrochus Erichson are transferred to two new genera, Nototrochus and Paratrochus. Holotrochus ferrugineus Broun is designated as type species of Nototrochus, which also includes H. montanus Broun. A new species, P. tardus, is designated as type-species of Paratrochus. Holotrochus brevipennis and H. caecus (both of Broun), H. helmsi, H. vagepunctus, H. anophthalmus, and H. microphthalmus (all of Fauvel), H. monstrosus and H. arrowi (both of Bernhauer), and 27 new species are included in Paratrochus. A male character, the 'copulatory piece', is well developed in this group and distinctive for each species. Though not previously used in staphylinid taxonomy, it is used here for species separation and is illustrated in scanning electron photomicrographs. Keys to identification are provided, and some aspects of phylogeny, ecology, and distribution are discussed.
