Gerasimos 'Gerry' Cassis
Australian Museum, Sydney, Australia


     I am a Principal Research Scientist at the Australian Museum, in Sydney, Australia. I have been at the Museum since 1989 and my position is principally concerned with the systematics, biodiversity and ecology of insects. My main research interest is in the systematics of the Heteroptera, particularly those of the Australian region. My current research projects concern the systematics and biogeography of the families Gelastocoridae, Miridae, Tingidae, Reduviidae, Thaumastocoridae, Scutelleridae and Pentatomidae. I currently have five PhD students, of which two are working on the systematics of the Heteroptera: 1. Nik Tatarnic (Miridae: Orthotylinae: Halticini); 2. Annie Noack (Thaumastocoridae). The other PhD students are working on ecological projects involving Heteroptera.

        Previous to my work at the Australian Museum, I worked for five years at the Australian National Insect Collection, CSIRO, Canberra, where I worked on the systematic catalogues of the Australian Heteroptera and Scarabaeoidea. I obtained my PhD from Oregon State University (Major Professor: Dr Jack Lattin) on the systematics of the mirid tribe Dicyphini. I obtained my BSc (Honours) at the University of Sydney (Major Professor: Fred McDonald) where I worked on Australian scutellerids. 

         My work on Pentatomoidea is presently concerned with the systematics of the Australian scutellerids and pentatomids. In conjunction with my colleague Emma Betts, I have produced a webkey to the Australian genera of Pentatomidae (see below). I am also about to submit an updated treatment of the Australian Scutelleridae with my colleague Loren Vanags. I am also engaged in a revision of the enigmatic pentatomid genus Caridophthalmus with my colleague David Rider from North Dakota State University. David and I have also discussed undertaking a review of the pentatomine tribe Diemenini. In the coming years I intend to work more extensively on Old World scutellerids, and am currently undertaking preliminary morphological investigations of the genera Coleotichus and Lampromicra.
