A revision of Park (Staphylinidae, Pselaphinae).

We revise the genus Park, redefining and redescribing the two previously known species, Park and Park, and adding ten new species: Caterino & Vásquez-Vélez, , Caterino & Vásquez-Vélez, , Caterino & Vásquez-Vélez, , Caterino & Vásquez-Vélez, , Caterino & Vásquez-Vélez, , Caterino & Vásquez-Vélez, , Caterino & Vásquez-Vélez, , Caterino & Vásquez-Vélez, , Caterino & Vásquez-Vélez, , and Caterino & Vásquez-Vélez, . The genus is still only known from a relatively small area in the southern Appalachian Mountains, but the diversity is much greater than previously suspected. The new species exhibit considerable diversity in male secondary sexual characters. A preliminary phylogenetic analysis cannot conclusively resolve the polarity of eye and wing reduction across Speleobamini, but the monophyly of Park's subgenus Fusjugama, if expanded to include all species with full-eyed and winged males, is not supported, and we therefore synonymize it with
