New host for Lernaea cyprinacea (L.) (Copepoda, Lernaeidae) in Argentina

Abstract

Lernaea cf. cyprinacea (L.) is recorded for the first time as ectoparasite of Astyanax hermosus Miquelarena, Protogino y López, 2005 (Teleostei: Characiformes: Characidae). The hosts were captured in the Cosquín River (Department Punilla), Province of Córdoba. Although the parasite has been recorded in various localities of this mediterranean province, it is the first record of the parasite in this host.
