Two new species of pselaphine staphylinids in the genus Batrisodes are described: B. (Declivodes) dorothae Ferro and Carlton from Feliciana Preserve, Louisiana; and B. (Babnormodes) spretoides Ferro and Carlton from Great Smoky Mountains National Park, Tennessee. They differ from all other described Batrisodes species in secondary male characters, especially details of the frontal region of the head. These two species bring the total diversity of the genus in North America to 88 species. Specimens were imaged using light microscopy, scanning electron microscopy, and X-ray microtomography (micro-CT) techniques. Utility of multiple imaging techniques, especially micro-CT, is discussed.
