Summary: | Alcataenia campylacantha (Krabbe, 1869) is redescribed and reported for the first time from pigeon guillemots, Cepphus columba Pallas, in Alaska. Specimens of this cestode were also found in black guillemots, Cepphus grylle (Linnaeus) at Point Barrow, Alaska. There were no substantial differences in morphological characters between populations of this cestode from the North Atlantic and North Pacific basins. Additionally, Alcataenia sp. indet. is reported, with a partial description, from Kittlitz's murrelets, Brachyramphus brevirostris (Vigors), in Alaska. This constitutes the first record of dilepidid cestodes from birds of the genus Brachyramphus Brandt. French abstract: On trouvera ici une nouvelle description d’Alcataenia campylacantha (Krabbe, 1869) rencontré pour la première fois chez des guillemots du Pacifique, Cepphus columba Pallas, en Alaska. Le cestode a également été trouvé chez des guillemots à miroir Cepphus grylle (L.) en Alaska. Il n’existe pas de différences morphologiques importantes entre la population du basin de l’Atlantique Nord et celle du bassin du Pacifique Nord. Un autre cestode, Alcataenia sp. indét. a été trouvé chez des alques pâles, Brachyramphus brevirostris (Vigors) en Alaska; on en trouvera ici une description partielle. Il s’agit là de la première découverte d’un cestode dilapididé chez des oiseaux du genre Brachyramphus Brandt. |
