Usage Notes

A monogeneric family established by Kasap and Crowson in 1975. The common name 'travertine beetles' refers to their association with calcium carbonate deposits in freshwater systems. The family contains approximately 21 species. Formerly treated as a subfamily of Hydrophilidae or considered related to Dryopidae, but now recognized as a distinct lineage within the superfamily Hydrophiloidea or alternatively placed in its own superfamily Lutrochoidea depending on classification system.
