Abstract

ABSTRACT Examination of museum collections revealed the presence of two species of Gastrotaenia Wolffhügel, 1938 (Cestoda: Hymenolepididae) in Australian anatid birds. Gastrotaenia dogieli (Ginetsinskaya, 1944) was found in the gizzard of the following species of Australian ducks from New South Wales: Anas castanea (Eyton), Anas rhynchotis Latham, Anas gracilis Buller, Aythya australis (Eyton), Chenonetta jubata (Latham) and Malacorhynchus membranaceus (Latham). Gastrotaenia cf. paracygni Czapliński & Ryžikov, 1966 was found in the proventriculus of black swans (Cygnus atratus (Latham)) from New South Wales and Victoria. The two species are reported for the first time from Australia. Specimens of Gastrotaenia without scoleces, and therefore not identifiable to species, were present in Anas superciliosa Gmelin and Biziura lobata (Shaw).
