Abstract

Eight species of cestodes belonging to the genus Andrya Railliet, 1883, have been described from North American rodents. To the present time, 6 of these have been considered valid (A. primordialis Douthitt, 1915; A. macrocephala Douthitt, 1915; A. neotomae Voge, 1946; A. microti Hansen, 1947; A. sciuri Rausch, 1947; A. ondatrae Rausch, 1948). The genus Andrya was separated by Kirschenblatt (1938) into two subgenera, depending upon the presence or absence of a prostate gland. Of the North American species, only one (A. primordialis) possesses a prostate gland. Since we are concerned essentially with the other 5 closely-related species, A. primordialis is only briefly considered. The purpose of this paper is to present the data derived from a detailed study of morphological variation in certain of these cestodes, together with the resulting nomenclatural changes.
