Revision of the Mexican Genus Mitys Champion (Tenebrionidae: Stenochiinae: Cnodalonini)

The flightless Cnodalonini genus MitysChampion, 1885 is revised. Lectotypes are designated for Mitys laevisChampion, 1885 and Mitys inflatusChampion, 1885, and the holotype of Mitys opacusChampion, 1885 is imaged. Mitys opacusChampion, 1885 is synonymized with Mitys politus (Breme, 1842). Three additional species are described herein: M. durangoensissp. nov., M. rileyi, sp. nov., and M. sprouseisp. nov. The genus is currently known only from Mexico, and appears to occur primarily in montane habitats based on existing locality records. Generic affinities between Mitys and other Neotropical Cnodalonini genera are discussed, particularly the relationship between Mitys and OxidatesChampion, 1886. A key to the known Mitys species and distribution maps are provided.
