The manual provides keys and descriptions of all North American species of Stenonema mayflies and consolidates information from the literature on their ecology, environmental requirements, and pollution tolerance. Accounts of each species include synonymy, nymphal description, collection records, and a distribution map. The 31 species described and keyed include three recently described species, four new synonyms, two resurrected species, and new combinations involving three additional species and subspecies. Twelve species and one subspecies are classified as intolerant to organic pollution, eight species as tolerant of mild pollution, and seven species and two subspecies as tolerant to moderate pollution.
