Two new species of Cloacina von Linstow, 1898, C. ridei sp. nov. and C. biscoei sp. nov. are described from the stomach of the banded hare wallaby, Lagostrophus fasciatus (Peron & Lesueur, 1807) from Western Australia. The two species differ from all congeners in having the excretory pore at the level of the nerve ring and the externodorsal ray arising from the dorsal ray. In spite of the relatively poor state of preservation of the nematodes, the two species are distinguishable from one another by the shape of the oesophagus, which is elongate and has combs in the bulb in C. ridei and in the shape of the buccal capsule, that of C. biscoei having an undulating anterior margin and in the shape of the cephalic papillae, with C. ridei having an enlarged distal segment and C. biscoei having a tiny distal segment.
