A revision of the Australian genus Blackburnium Boucomont (Coleoptera : Scarabaeidae : Geotrupinae)

Abstract

The Australian genus Blackburnium Boucomont is revised; 30 species and subspecies are recognized and keyed. Fifteen previously proposed names are considered valid. Fifteen new taxa are described as follows: acutipenne, ambiguum, angulicorne convexicolle, barretti, brooksi, canningense, centrale, cooperi, darwinense, harslettae, monteithi, neocavicolle, pauperculum, seticolle, and triceratops. Head and pronotal characters and male genitalia are figured by means of scanning electron micrographs. Available biological information and distribution data are summarized following the species descriptions.
