Tetrabothrius sp. (Cestoda: Tetrabothriidae) and Stegophorus stellaepolaris (Nematoda: Acuariidae) Collected from a Short-Tailed Albatross (Diomedea albatrus)

Abstract

The cestode Tetrabothrius sp. and the nematode Stegophoms stellaepolaris were collected from the alimental canal of a dead short-tailed albatross (Diomedea albatrus), which was obtained during a field research in Torishima Island in the Izu Islands, Japan. Their morphology and differentiation from other species are described. This is the first report of S. stellaepolaris from D. albatrus in Japan.
