title: Uterotrema Australispinosa n. gen., n. sp. (Digenea: Spirorchidae), a parasite of a freshwater turtle Emydura macquarii from southern Queensland, Australia.
abstract: Uterotrema australispinosa n. gen., n. sp. from the heart of the Murray River turtle Emydura macquarii (Pleurodira: Chelidae) is distinguished from other members of the Spirorchidae by the presence of a voluminous uterus; a single, lobed testis occupying the posterior quarter of the body; linear rows of 5-6 spines arranged along the lateral margins of the hindbody from the posterior rim of the acetabulum to the posterior end of the body; and the posterior end ventrally curved with a dorsal cluster of spines near the terminal end. This is the first report of a spirorchid from a member of the family Chelidae and from Australia.
