Hydrochidae
Elongate Water Scavenger Beetles
Hydrochidae is a family of aquatic beetles in the order Coleoptera, containing a single genus Hydrochus with approximately 180–200+ species worldwide. These small elongate water scavenger beetles are found in freshwater habitats across multiple continents including Europe, Asia, Africa, and the Americas. The family is sometimes treated as the subfamily Hydrochinae within Hydrophilidae. Species-level taxonomy is well-developed, with recent revisions documenting substantial diversity in Central America (26 species), South America (77 species in Bolivia, Brazil, and Paraguay alone), and the Mediterranean region.
