The Nearctic Neoperla are reviewed. Eight species, placed in two nominal groups, are recognized. Neoperla carlsoni, new species, N. catharae, new species, N. choctaw, new species, N. freytagi, new species, N. gaufini, new species, and N. stewarti, new species, are described for male, female, and egg. Male holotypes and female allotypes are designated for each species. Neoperla mainensis Banks and N. clymene (Newman) are redescribed and mainensis is raised to species. Descriptions are supported by original drawings and stereoscan photomicrographs. Relationships of Nearctic species groups to the world fauna are discussed.
