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

Abstract

The Rugopharynx australis complex from macropodidmarsupials is revised. The nominal taxon is limited to specimens occurring inthe type host, Macropus rufus, and similar nematodes insympatric host species, M. fuliginosus,M. giganteus, M. robustus andPetrogale xanthopus. A single occurrence is reported inM. dorsalis. The following new species are described:R. macropodis, sp. nov. fromM. fuliginosus and M. giganteus;R. pi, sp. nov. fromM. rufogriseus and M. parryi;R. rho, sp. nov. from M. eugenii,M. fuliginosus, M. irma andPetrogale lateralis;R. longispicularis, sp. nov. fromM. parma; R. mu, sp. nov. fromWallabia bicolor; R. spratti, sp.nov. from M. rufogriseus; R. chi,sp. nov. from Thylogale billardierii;R. tau, sp. nov. from Th. thetisand R. petrogale, sp. nov. fromPetrogale penicillata, P. herbertiand P. inornata.Rugopharynx alpha(Johnston & Mawson,1938) isresurrected for specimens from Petrogale lateralis fromcentral Australia and north western Queensland. Specimens fromPetrogale lateralis pearsoni from South Australia andP. l. lateralis from Western Australia were not assignedto a species. A key to the species of Rugopharynx isprovided.
