First record of Australapatemon burti and Paramonostomum pseudalveatum (Digenea) from Anas georgica (Aves, Anseriformes) in Chile

Abstract

An examination of specimens of Anas georgica Gmelin (Anatidae) from Región del Bio-Bio and Region del Maule, Chile, revealed the presence of two digenean species reported for the Holartic Region: Australapatemon burti (Miller, 1923) Dubois, 1968 (Strigeidae) and Paramonostomum pseudalveatum Price, 1931 (Notocotylidae). A. burti parasitized ducks from both regions and P. pseudalveatum parasitized only ducks from Region del Bio-Bio. The digeneans were mounted in toto, described and illustrated. The morphology and dimensions of specimens studied correspond with their original descriptions and new morphometrical data and morphological characters are given. The reports of A. burti and P. pseudalveatum in A. georgica represent a new host record and the first record of the genera Australapatemon Sudarikov, 1959 and Paramonostomum Lühe, 1909 from Chile. © 2007 W.
