Review of the type material for two Palaeozoic ostracod species from southeast Australia

Abstract The ‘Illaenus’ band of the Costerfield Siltstone in the Costerfield-Heathcote area contains pockets of Silurian (lower Wenlock) deposits that contain a rich invertebrate fauna. Several assemblages from the ‘Illaenus’ band have been described and include ostracod species referable to 13 genera. These specimens were housed at the Australian Government Bureau of Mineral Resources in Canberra, which was damaged by fire in 1953. Of the documented ostracod specimens, only three remain, but are in a degraded state. We reinterpret this historically important material as representing the types of Ctenobolbina proxima and Kayatia prima. Tamara T.A. Camilleri [tamara.camilleri@deakin.edu.au] and Mark T.
