LUNASCHI, Lía Inés  y  DRAGO, Fabiana Beatriz. Digenean parasites of six species of birds from Formosa Province, Argentina. Rev. Mex. Biodiv. [online]. 2009, vol.80, n.1, pp.39-46. ISSN 2007-8706.

The aim of this paper is to increase the knowledge of the diversity of digenean parasites from birds collected in Formosa Province, Argentina. The helminthological survey of 15 specimens of 6 bird species revealed the presence of 5 digenean species: Clinostomatopsis sorbens (Braun, 1899) and Clinostomum marginatum (Rudolphi, 1819) (Clinostomidae) from the esophagus of Tigrisoma lineatum (Boddaert); Glaphyrostomum propinquum Braun, 1901 (Brachylaimidae) from the cloaca of Guira guira (Gmelin); Stomylotrema vicarium Braun, 1901 (Stomylotrematidae) from the cloaca of Busarellus nigricollis (Latham) and Buteogallus meridionalis (Latham); and Athesmia heterolecithodes (Braun, 1899) (Dicrocoeliidae) from the bile canaliculi of G. guira, Milvago chimachima (Vieillot) and Rostrhamus sociabilis (Vieillot). The present study adds new morphometric data on 2 species of digeneans (C. sorbens and G. propinquum) and new host records for C. sorbens, G. propinquum, A. heterolecithodes and S. vicarium. The genera Clinostomatopsis Dollfus, 1932 and Glaphyrostomum Braun, 1901 are reported for the first time in Argentina.
