Description of Laccomimus gen. n. And eleven new species from the Neotropical region (Coleoptera, Dytiscidae, Laccophilinae)
A new genus of laccophiline diving beetles, Laccomimus gen. n., is here described on the basis of a large number of spec-imens from various collections formerly misidentified as members of the Neotropical genus Laccodytes Régimbart, 1895. Except for similar size, however, the new genus is not closel...
