Historical Biogeography of Holarctic Cymbiodyta Water Scavenger Beetles in the Times of Cenozoic Land Bridge Dispersal Routes

The genus Cymbiodyta Bedel, 1881 (Coleoptera: Hydrophilidae: Enochrinae) comprises 31 species distributed in both the Old and New World portions of the Holarctic realm. Although the species and taxonomy are relatively well known, the phylogenetic relationships among Cymbiodyta and the evolutionary history of the genus remain unexplored. To understand the systematics and evolution of this lineage, we sequenced five gene fragments for about half...
