Abstract: | Allocreadium pichi n. sp. (Trematoda: Allocreadiidae) is described from the intestine of Galaxias maculatus (Osteichthyes: Galaxiidae) from Moreno Lake in Patagonia, `Argentina. This species is distinguished from A. patagonicum Shimazu, Urawa &; Coria, 2000, the other species recorded in the area, by its smaller body size, the diagonal position of the testes and different ratios of the suckers, testes and cirrus-sac in relation to body size. In addition, the synonymy of A. patagonicum withPolylekithum percai Ostrowski de Núñez, Brugni &; Viozzi, 2000 is proposed herein. |
