Revision of the Rugopharynx australis (Moennig, 1926) complex (Nematoda : Strongyloidea) from macropodid marsupials

The Rugopharynx australis complex from macropodid marsupials is revised. Th e nominal taxon is limited to specimens occurring in the type host, Macropu s rufus, and similar nematodes in sympatric host species, M. fuliginosus, M . giganteus, M. robustus and Petrogale xanthopus. A single occurrence is re ported in M. dorsalis. The following new species are described: R. macropod is, sp. nov. from M. fuliginosus and M. giganteus; R. pi, sp. nov. from M. rufogriseus and M. parryi; R. rho, sp. nov. from M. eugenii, M. fuliginosus , M. irma and Petrogale lateralis; R. longispicularis, sp. nov. from M. par ma; R. mu, sp. nov. from Wallabia bicolor; R. spratti, sp. nov. from M. ruf ogriseus; R. chi, sp. nov. from Thylogale billardierii; R. tau, sp. nov. fr om Th. thetis and R. petrogale, sp. nov. from Petrogale penicillata, P. her berti and P. inornata. Rugopharynx alpha (Johnston & Mawson, 1938) is resur rected for specimens from Petrogale lateralis from central Australia and no rth western Queensland. Specimens from Petrogale lateralis pearsoni from So uth Australia and P. l. lateralis from Western Australia were not assigned to a species. A key to the species of Rugopharynx is provided.
