Cylicospiruraheydoni (Baylis, 1927) Mawson, 1968
This species was originally described from a possum, Dasyurus sp., collected in Cairns, North Queensland, Australia (Baylis, 1927). In 1968, the worms were redescribed by Mawson using specimens from Dasyurusquoll from Tasmania and Dasyuropsmaculatus from New South Wales. In 1997, Milstein and Goldsmid reported finding Cylicospiruraheydoni in 4 of 39 cats collected in southern Tasmania. The six anteriorly directed ribs in the buccal cavity of Cylicospiruraheydoni are each with a single pointed denticle.
