INTRODUCTION Coleocoptus Aurivillius 1893 is a monotypic phoracanthine genus of exclusively Australian-New Guinean distribution. Aurivillius (1893) proposed the genus based on Coptocercus sexmaculatus Hope 1844. In 1912, Aurivillius synonymised Coleocoptus sexmaculatus (Hope) with C. senio (Newman) (= Phoracantha senio Newman 1840). The synonymy was confirmed when the types of these two species were examined. Coleocoptus is most closely related to Phoracantha Newman, and according to Wang's (1994b) cladistic analysis, they are in fact sister genera. Coleocoptus differs from Phoracantha in having the prothorax distinctly longer than wide, and the elytra with truncate apices. Although Coleocoptus is monotypic, its distribution is almost as exten-sive as that of Phoracantha which includes at least forty species, many of which have very localised distributions (Wang 1995b). The adult of C. senio has never been well described and illustrated but the immature stages were well described by Duffy (1953, 1963) based on specimens obtained from Syncarpia in New South Wales. Taxonomic terminology follows Wang (1993a,b; 1994a,b; 1995a,b; 1996) and Wang et al. (1994). Specimens for this study were borrowed from the following: Australian Museum, Sydney (AM), Australian National Insect Collection, Canberra (ANIC), Natural History Museum, London (BMNH), Museum of Victoria, Melbourne (MV), Northern Territory Museum, Darwin (NTM), Oxford University Museum, Oxford (OUM), Queensland Museum, Brisbane (QM), South Australian Museum, Adelaide (SAM), and University of Queensland Insect Collection, Brisbane (UQIC). The author's collection has been deposited in MV. Distribution data were obtained from specimens examined. GENUS COLEOCOPTUS AURIVILLIUS Coleocoptus Aurivillius 1893:160.
