Diversity and taxonomic review of Leptusa Kraatz (Coleoptera: Staphylinidae: Aleocharinae) from Great Smoky Mountains National Park, U.S.A., with descriptions of four new species

A taxonomic review of the beetle genus Leptusa in Great Smoky Mountains National Park identifies ten species, including four newly described: L. (Adoxopisalia) pseudosmokyiensis, L. (A.) stocksi, L. (Dysleptusa) gimmeli, and L. (Eucryptusa) ferroi. The study also documents the previously unknown female of L. (D.) pusio, providing detailed illustrations and diagnostic keys for 16 of the 18 eastern U.S. species. This research highlights the 'Overlooked Syndrome,' where undescribed species persist in well-studied regions, emphasizing the need for continued taxonomic exploration even in extensively documented areas.
