Abstract

Re-examination of Dithyridium cynocephali Ransom 1905, a metacestode parasite from the thylacine Thylacinus cynocephalus, has revealed it to be morphologically indistinguishable from metacestodes of the tapeworm Anoplotaenia dasyuri found in the eastern quoll Dasyurus viverrinus and the spotted-tailed quoll D. maculatus, in Bennett's wallaby Macropus rufogriseus rufogriseus and in the Tasmanian pademelon Thylogale billardierii. The Tasmanian devil Sarcophilus harrisii is the predominant definitive host for A. dasyuri, but the two quoll species can also serve as definitive hosts. It is considered likely that quolls may act as intermediate hosts through the occasional consumption of Tasmanian devil faeces containing infective A. dasyuri eggs. The thylacine may have become infected with A. dasyuri in a similar manner, by engaging in coprophagy in the wild or in captivity.
