Digenean parasites of the Neotropic Cormorant, <i>Phalacrocorax brasilianus</i> (Gmelin, 1789) (Aves: Phalacrocoracidae) from Argentina: distribution extension and new host records

Abstract

Thirteen specimens of <i>Phalacrocorax brasilianus</i> (Gmelin, 1789) from three areas of the Chaqueña Subregion of Argentina were examined for digeneans. Ten species were found: four diplostomids (<i>Austrodiplostomum mordax</i>, <i>A. ostrowskiae</i>, <i>Tylodelphys adulta</i> and <i>Hysteromorpha triloba</i>), three echinostomatids (<i>Drepanocephalus spathans</i>, <i>Paryphostomum segregatum</i>, and <i>P. parvicephalum</i>), one strigeid (<i>Strigea falconis brasiliana</i>), one psilostomid (<i>Ribeiroia ondatrae</i>) and one prosthogonimid (<i>Prosthogonimus ovatus</i>). <i>Tylodelphys adulta</i> and <i>S. f. brasiliana</i> are reported for the first time as parasites of <i>P. brasilianus</i> and new geographical records are presented.
