Feather mites (Acarina) of the parakeet, Melopsittacus undulatus (Shaw) (Aves: Psittacidae)

The parakeet (or budgerigar) has been transported to many regions of the world. Two species of feather mites, Protolichus lunula (Robin) (Pterolichoidea: Pterolichidae) and Dubininia melopsittaci n. sp. (Analgoidea: Xolalgidae), are specific to this host; from distribution records, these ectoparasites probably have been distributed worldwide with their hosts.
