title: Taxonomic revision of Tatria Kowalewski, 1904 (Cestoda: Amabiliidae): redescriptions of T. appendiculata Fuhrmann, 1908 and T. duodecacantha Olsen, 1939, a key and an amended diagnosis of Tatria (sensu stricto).
abstract: Tatria appendiculata Fuhrmann, 1908 is redescribed on the basis of syntypes from Tachybaptus dominicus in Brazil and voucher specimens from the same host species in Cuba previously recorded by Rysavy & Macko (1971). Paratypes of T. duodecacantha Olsen, 1939 from Podilymbus podiceps in the USA are also redescribed and, in contrast with the opinion of Ryzhikov & Tolkacheva (1981), the species is recognised as valid. The major reliable diagnostic characters of Tatria and the distinguishing criteria applicable at the species level are re-evaluated. An amended generic diagnosis of Tatria (sensu stricto) and an identification key to its constituent species are presented.
