Novel host associations for the fungus beetles Cnecosa insueta and Thallis vinula (Coleoptera: Erotylidae: Erotylinae) in Tasmania

Novel basidiocarp hosts in the fungal families Fomitopsidaceae and Polyporaceae are documented for two Tasmanian species of fungus beetle (Erotylidae). Large aggregations of Cnecosa insueta (Crotch) were found feeding on Neolentiporus maculatissimus (Lloyd) Rajchenb and Thallis vinula (Erichson) on Ryvardenia campyla (Berk.) Rajchenb. Field observations of both beetles and hosts are documented.
