Capnia caryi, a new species of Nearctic Capniidae, is described from adults collected from high-elevation locations in the Southern Rocky Mountains of southern New Mexico and Arizona. Males are distinguished by their rounded club-shaped epiproct and sclerotized knobs on abdominal terga 8 and 9. Females possess a darkly sclerotized subgenital plate that covers most of tergum 8 and is produced posteriorly as a pair of broadly rounded lobes.
