Berosini
Berosini is a tribe of water scavenger beetles (Hydrophilidae: Hydrophilinae) comprising 364 species in five genera: Allocotocerus, Berosus, Derallus, Hemiosus, and Regimbartia. The tribe exhibits significant larval ecological diversification, with evolutionary shifts between benthic and cryptic habitats documented. Phylogenetic analysis supports two major clades: one containing Hemiosus and Berosus, and another containing Derallus, Regimbartia, and Allocotocerus.
