Registros inéditos de mariposas diurnas (Lepidoptera: Papilionoidea) para Argentina III. Colección Núñez Bustos en el MACN.

Twenty-one species of diurnal butterflies are reported, from five provinces in Argentina, which were previously unrecorded from that country. One family (Hedylidae) and six genera are new to Argentina (Allosmaitia, Heterosais, Siderone, Cantha, Lychnuchus and Macrosoma). The material is part of the author's collection, currently housed in the MACN. These new records are illustrated and comments are provided. [ABSTRACT FROM AUTHOR]
