Résumé

Redescription de l’espèce type du genre Peramelistrongylus Mawson, I960. — Description de Profilarinema hemsleyi n. gen. n. sp., parasite de Trichosurus vulpecula de Western Australia. Le genre, proche de Filarinema, en diffère essentiellement par l’absence de l’appareil buccal complexe qui caractérise ce dernier.

Les genres Batrachostrongylus Yuen, 1963, parasite d’Amphibiens, Peramelistrongylusparasite de Peramelioidea et Dasyuroidea, Profilarinema, parasite de Phalangeridae et Filarinema Mönnig, 1929, parasite de Macropodidae, nous paraissent constituer une lignée homogène distincte des autres Trichostrongyloides australiens.

Abstract

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 characterises the latter genus.

The genera Batrachostrongylus Yuen, 1963, parasitic in amphibians, Peramelistrongylus, 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.
