Alcataenia longicervica sp. n. (Cestoda: Dilepididae) is described from murres, Uria spp., in Alaska and other localities in the Pacific basin. From Alcataenia armillaris (Rudolphi, 1810), which it most closely resembles, A. longicervica is distinguished by larger size of organs (cirrus sac, vitelli...

From Alcataenia armillaris (Rudolphi, 1810), which it most closely resembles, A. longicervica is distinguished by larger size of organs (cirrus sac, vitelline gland, and seminal receptacle), greater number of testes, and extremely long neck.
