Key for identification of the litter species within the A. loweae View in CoL species group

This key will allow determination of the loweae -group species and their allies in the southern Appalachian Mountains. External features are of limited diagnostic value, and the key is based mostly on genitalia structures of both sexes, so correct identification of the specimen usually requires dissection.
