Descripción
Sumario:The tribe Berosini (Coleoptera: Hydrophilidae) is represented in South America by the genera Berosus  Leach, Hemiosus Sharp and Derallus Sharp. Distributional data from new material and from previous publications are given and a classification of the type of distribution is proposed. Few species are strictly Neotropical. Most species are associated with one or more of the main river systems (Paraguay-Paraná-Plata, Amazonas, Orinoco, Saõ Francisco and Desaguadero-Colorado-Negro), with latitudinal influence in the Paraná-Plata. Species of Berosus and Derallus  are mostly distributed along the rivers, those of Hemiosus are located on sandy or (rarely) gravelly substrates, with influence of the origin of sediments (Andean, Brasilia shield, etc.).
