Cymbiodyta is a of water scavenger beetles (Hydrophilidae: Enochrinae) comprising 31 described . The genus exhibits a strikingly disjunct distribution: 28 species occur in the Americas, while only three species inhabit the Palearctic region. A fossil species from Eocene Baltic amber (C. samueli) confirms the genus has persisted in Europe since at least the Eocene, supporting biogeographic reconstructions indicating an ancient Euro-American distribution dating to the Late Cretaceous when land connections existed between North America and Europe.

Distribution
Americas (28 ) and Palearctic (3 species: C. marginella, C. lishizheni, C. orientalis). GBIF records document occurrence in Denmark, Norway, and Sweden. The fossil C. samueli from Eocene Baltic amber (Lithuania) confirms European presence since at least 34 million years ago. Biogeographic analysis indicates the ancestral range encompassed both Europe and North America, with European lineages representing ancient relicts that have declined to a single surviving species (C. marginella).
