Abstract
A Heterophyes species from the small intestine of the water rat, Hydromys chrysogaster, in Australia is described in detail. The specimens are assigned to H. nocens, a species which many authors believed to be a synonym of H. heterophyes. From this study, H. nocens is considered a valid species as it differs from H. heterophyes in the number of sclerites on the gonotyl, the course of the uterus, coefficients of allometric growth of the suckers and the presence of genital sinus spines.
