A revision of Australian Thrasorinae (Hymenoptera: Figitidae) with a description of a new genus and six new species

Abstract

A new genus of Thrasorinae (Hymenoptera: Figitidae) is described from Australia, and includes specimens reared from an unidentified Ophelimus species (Eulophidae: Ophelimini) on Eucalyptus cinerea (Myrtaceae). Mikeius, new genus, includes six species: M. berryi sp. n., M. gatesi sp. n., M. grandawi sp. n., M. hartigi (Girault) n. comb., M. neumanni sp. n. and M. schauffi sp. n.; M. hartigi is designated as the type species of Mikeius. Thrasorus Weld is revised, and the description of T. schmidtae sp. n. is provided, as well as a redescription of T. pilosus Weld. All records to date indicate that species of Mikeius and Thrasorus are associated with hosts that induce galls on species of Acacia and Eucalyptus, although most of these host records await verification. A list of world species of Thrasorinae is provided
