Berosus (Enoplurus) quadridens Chevrolat 1863

Berosus quadridens is a species of hydrophilid beetles from Mexico, Guatemala, Nicaragua, Costa Rica and Cuba. It was previously considered a synonym of Berosus truncatipennis.

Based on the specimens examined for this study, we may confirm the occurrence of Berosus quadridens for Mexico, Guatemala, Nicaragua, Costa Rica and Cuba. Van Tassell (1966) also maps one record from Panama, but does not cite label data. In Cuba, the species is known from the western (including Isla de la Juventud special municipality) and eastern regions.
