n. g., n. g., and n. sp.: New Genera and a New Species of Nematode (Strongylida: Phascolostrongylinae) Parasitic in Australian Macropodid and Vombatid Marsupials.

The strongyloid nematodes belonging to the subfamily Phascolostrongylinae occur primarily in the large intestines of macropodid and vombatid marsupials. Current molecular evidence suggests that the two nematode species, and , from macropodid marsupials are distant from their respective congeners. Furthermore, specimens of from the large intestines of the southern hairy-nosed wombat () and the common wombat () are genetically distinct. This study aimed to describe the new genera n. g. (with n. comb. as the type species) from the eastern grey kangaroo, n. g. (with n. comb. as the type species) from the swamp wallaby and a new species n. sp. from the common wombat, using light and scanning electron microscopy.
