Diandrya is a genus of cestode parasites that are known from marmots (Marmota spp.) in North America. The species Diandrya composita , described along with the genus by J. G. Darrah in 1930, is known from all North American marmots except the woodchuck (M. monax). The species D. vancouverensis , described by T. F. Mace and C. D. Shepard in 1981, is only known from the Vancouver Island marmot (M. vancouverensis), an island endemic on Vancouver Island.^[1]^[2] Subsequent research confirmed D. vancouverensis to be genetically unique from D. composita.^[3]
