Great Basin Naturalist


A variety of amphibian, reptilian, avian, and mammalian hosts were used in experimental development of Posthodiplostomum minimum. Results of this study indicate that the organs of reproduction (testes and ovary) as well as the vitelline gland and egg underwent host-induced morphological variations. Due to the lack of host specificity of P. minimum as well as the overlap of reported egg and body sizes of species of Posthodiplostomum, it is apparent that several reported species are not valid.
