Revision of the Australian Ceratocanthinae (Coleoptera, Scarabaeoidea, Hybosoridae)

Abstract

The Australian fauna of Ceratocanthinae (Coleoptera, Scarabaeoidea, Hybosoridae) is revised. Two genera are present, both shared with Asia, with a total of seven species, all localized in eastern Queensland and all except one, endemic to Australia. Cyphopisthes is comprised of three species, two of them new (Cyphopisthes yorkensis sp. n. and C. monteithi sp. n., the latter, together with C. descarpentriesi Paulian, 1977 displaying an unusual ecology, with occurrence in the southern Queensland dry rainforest/scrub habitats), and Pterorthochaetes is comprised of four species, two of them new (Pterorthochaetes danielsi sp. n. and P. storeyi sp. n.). Descriptions, distribution, ecological remarks and a key to species are provided. © Alberto Ballerio.
