[Peramelistrongylus Mawson, 1960 and Profilarinema n. gen., trichostrongyloid nematodes apparently transitional between the Strongyloidea and the atypical genus Filarinema Mönnig, 1929 (author's transl)].
Peramelistrongylus skedastos Mawson, 1960, type species of the genus Peramelistrongylus Mawson, 1960 is redescribed. Also described is Profilarinema hemsleyi n. gen., n. sp. from Trichosurus vulpecula in Western Australia. The new genus, which is similar to Filarinema, differs from it essentially by the absence of the complex buccal armature which characterizes the latter genus. The genera Batrachostrongylus Yuen, 1963, parasitic in amphibians, Peramelistromgylus, parasitic in perameloid and dasyuroid marsupials, Profilarinema parasitic in phalangerid marsupials and Filarinema Mönnig, 1929, parasitic in macropodid marsupials, seem to us to constitute a homogeneous evolutionary line distinct from the other Australian trichostrongyloids.
