A new genus of epacteriscid calanoid copepod from an anchialine sinkhole on northwestern Australia

Bunderia misophaga gen. ct sp. nov. is described from an anchialine cenote located on the Cape Range peninsula, northwestern Australia. This is the fi rst epacreriscid calanoid known from Australia and represents the third gen us of this family of mainly stygobiont copepods recorded in the Indo-Pacifi c region. Ordinary phenetic analysis points to the monotypic Enantronoides Fosshagen, Boxshall, and Iliffe, from an anchialine cave on the Bahama Isla nds, as the closest relative of the new genus. This suggests an ancient, re lictual status for the new taxon. The predatory habits of the family Epacte riscidae are confirmed after the gut contents of Bunderia yielded remains o f a not-yet-described misophrioid copepod.
