Within the context of ongoing taxonomic revisions of terrestrial flatworms from Australia and the Subantarctic Islands of New Zealand: (1) a new subfamily of the Terricola, the Anzoplaninae, is erected, and some subantarctic terricolan taxa are reassigned to the new subfamily; (2) diagnoses for the subfamily Caenoplaninae and genus Coleocephalus are emended; (3) the new genera Anzoplana and Fyfea are erected; and (4) the new species Anzoplana trilineata is described. A lectotype is designated for Fyfea carnleyi (Fyfe).
