title: Two new species of Uterotrema (Digenea: Spirorchidae) parasitic in Emydura krefftii (Testudines: Chelidae) from Australia.
abstract: Two new species of Uterotrema (Digenea: Spirorchidae) are described from Emydura krefftii in northern Queensland, Australia. Both new species are smaller than the only previously described member of the genus and possess an oral sucker/ventral sucker ratio > 1. Uterotrema burnsi n. sp. possesses a thin, elongate uterus that is 25% of the total body length. The uterus of Uterotrema kreffti n. sp. is shorter, and it possesses vitellaria and a vitelline reservoir, neither of which were reported in the type species. Although reported here as distinct species they may represent a single species that sequentially changes reproductive roles during development in the definitive host.
