Studies on the Helminth Fauna of Alaska. XLV. \u3ci\u3eSchistotaenia srivastavai\u3c/i\u3e n. sp. (Cestoda: Amabiliidae) from the Red-Necked Grebe, \u3ci\u3ePodiceps grisegena\u3c/i\u3e (Boddaert)

The genus Schistotaenia Cohn, 1900, at present includes six species, all parasites of grebes (Podicipediformes). Among helminths found in a red-necked grebe, Podiceps grisegena (Boddaert), on October 18, 1966, at Anchorage, Alaska, were cestodes representing two species of Schistotaenia, of which one is described here as new. The host was an adult bird which evidently had been injured during migration. This cestode is named in honor of Dr. H. D. Srivastava, in recognition of his significant contributions to helminthological research
