Breinlia mackerrasae n.sp. is described from the short-nosed bandicoot Isoodon macrourus. It bears most similarity to B. dentifera, but differs in having larger spicules and in the arrangement of the anal papillae. Female worms from a ‘mumut’ (Peramelidae) are described, but as no males are available, their taxonomic status remains uncertain. These are the first records of Breinlia from peramelid marsupials.
