Abstract

Galactosomum stelleri sp. n. (Trematoda: Heterophyidae), a new trematode from the small intestine of the Steller's or northern sea-lion Eumetopias jubatus is described. An adult female specimen of E. jubatus collected from Indian Beach, Oregon, U.S.A., harbored over 100 specimens of these trematodes. The new species most closely resembles Galactosomum ubelakeri (Dailey, 1969) Pearson, 1977, and Galactosomum humbargari Park, 1936 but differs in body shape and size, lack of tegumental spines, length of esophagus, and ventral genital complex configuration. This is the third report of a species of Galactosomum from a marine mammal.
