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

“…There are two phenomena characterising Australian coccinellids: larger than average proportion of the representatives of the tribe Coccidulini in the local fauna and around 90% of Australian coccinellids feed on scale insects (Coccoidea), whereas elsewhere that proportion is much smaller. Large proportion of Coccidulini in local fauna is also characteristic of other Gondwanan continents such as southern South America and Africa; also, almost the whole native coccinellid fauna of New Zealand belongs to the tribe Coccidulini (Szawaryn et al 2022).…”
