Eucoleus potoroi sp. nov. (Nematoda: Trichinelloidea: Capillariidae) from the Bronchi and Bronchioles of Captive Potoroid Marsupials
Abstract:Eucoleus potoroi sp. nov. is described from the bronchi and bronchioles of the rufous rat kangaroo, Aepyprymnus rufescens (Gray, 1837), the long-nosed potoroo, Potorous tridactylus (Kerr, 1792) and the woylie, Bettongia penicillata Gray, 1837 in a captive colony at Cowan, New South Wales. It is distinguished from all other species of Eucoleus Dujardin, 1845 from Australian native mammals by the immense length of the ejaculatory duct and the very large ratio of mean total length of oesophagus to mean total length of posterior body in males. The only known occurrence of the parasite in captive colonies and the pathology associated with infection suggest that the parasite might be a parasite of introduced or volant eutherians in abnormal hosts. However, comparative examination indicated that E. potoroi is distinct from Eucoleus aerophilus (Creplin, 1839) from the trachea of cats, from Pearsonema feliscati (Diesing, 1851) from the bladder of cats and from Calodium hepaticum (Bancroft, 1893) from the liver of rats, the only capillariids known from introduced eutherians in Australia. It is also distinct from Aonchotheca miniopterae (Thomas, 1959) comb. nov. from the stomach of the bat, Miniopterus schreibersii (Kuhl, 1817).
