title: Allassogonoporus dromiciops n. sp. (Digenea: Allassogonoporidae) from Dromiciops gliroides (Marsupialia: Microbiotheriidae) in Patagonia, Argentina.
abstract: A new species of Allassogonoporus Olivier, 1938, from a naturally infected specimen of Dromiciops gliroides, is described. Adults of A. dromiciops n. sp. were recovered from the small intestine. This new species can be distinguished from all other species of the genus by having: the largest body and eggs, a lobed testes and ovary, a Y-shaped excretory vesicle and vitelline follicles beginning at the level of the posterior margin of the oral sucker. This is the first record of a species of Allassogonoporus in South America and the first record of a digenean parasitising D. gliroides.
