Lathrobium (Tetartopeus): natural history, phylogeny and revision of the nearctic species (Coleoptera: Staphylinidae)

Abstract: The eleven species of Lathrobium subgenus Tetartopeus from the Nearctic Region are revised. Thirteen specific names are placed in synonymy, L. convolutum sp.n. is described, and Deratopeus Casey is synonymized with Tetartopeus. A cladistic analysis suggests that Tetartopeus is monophyletic, and that five monophyletic species-groups are represented in the Nearctic Region.

Contains a key to species, with distribution maps for each species and many illustrations showing characters important for species identification.
