Abstract

In this study, we record for the first time a species of dobsonflies (Megaloptera: Corydalus) in the Central-West Brazilian, based on specimens of Corydalus diasi Navás, 1915 collected from a recently discovered population in the state of Mato Grosso do Sul. Specimens were obtained in December 2024 at Santa Virgínia Stream – Cascata do Cobre, Ponta Porã municipality, using active and passive light-trap techniques. Located in a regenerating Cerrado forest with Atlantic Forest influence, it presents rapids and waterfalls that support aquatic biodiversity. This record expands the known distribution of C. diasi to Brazilian states, highlighting the importance of continued sampling and taxonomic research in underexplored regions of Brazil.
