Description of Euchre gen. nov., a new Coccidulini genus (Coleoptera: Coccinellidae) from the Euchre Valley in Australia

Abstract

AbstractAustralia is inhabited by a very rich and mostly endemic fauna of ladybird beetles (Coccinellidae), with a relatively high proportion of taxa belonging to the tribe Coccidulini. Australian Coccidulini are grouped in 15 genera, of which 11 are endemic. Here, a new distinctive Australian Coccidulini genus and species is described—Euchre australis gen. et sp. nov., which is characterised by compact antennal club, long ventral antennal grooves on head capsule extending to anterior margin of prosternum, and presence of chin piece partially covering mouthparts in repose. Its relationship with other Australian Coccidulini genera is discussed.
