Abstract

Acanthagrion hildegarda Gloger, 1967 (Odonata: Zygoptera: Coenagrionidae) is a common inhabitant of lentic environments in Argentina and Uruguay. However, precise georreferenced data are scarce in the literature. This work provides the first updated georreferenced list of localities and map of distribution of A. hildegarda, including new country records for Brazil and departamental records for Uruguay, accompanied by illustrations and scanning photographs of its main diagnostic characters.
