Abstract

A redescription of both sexes of Erythrodiplax pallida (Odonata: Libellulidae) is provided based on specimens collected in shallow wetlands associated with flood plains from small streams to large rivers in Corrientes and Buenos Aires provinces, Argentina. The vesica spermalis morphology resembles those of the basalis and nigricans groups due to the presence of median and posterior lobes and the lack of paired lobes. Erythrodiplax pallida is easily distinguished from the other congeners by the white frons.

Keywords: dragonfly, vesica spermalis, adult, Neotropics, Argentina
