New distributional and ecological data of Gymnochtebius franki (Bruch, 1915) (Coleoptera, Hydraenidae) with an annotated key to the Argentinean species

Abstract

In this work we present new distributional data about Gymnochtebius franki (Bruch, 1915). We also described the environments and water bodies in which this species occurs and the importance about its conservation. Finally, we present an annotated key to the nine species of Gymnochtebius from Argentina. We also present a distributional map with updated information.
