Abstract —Collections of of the Leptophlebiidae, genera Eaton, Paralcptophlehia Lestage, Thraiilodes Ulmer, and Edmunds from the southwestern United States and northwestern Mexico are reviewed. Choroterpes (Choroterpes) oaxacaensis Brusca & Allen is synonymized with C. (C.) inornata Eaton. The nymph described as "D ' Allen & Brusca is the nymph of T. arizonicus McDunnough. New distributional records extend the known ranges of C. inornata, C. () mexicanus Allen, Paralep- tophlchia memorialis (Eaton), T. arizonicus, T. hrunneus Koss, T. salintis Kilgore & Allen, T. speciosus Traver, Traverella alhertana (McDunnough), and T. castanea Kilgore & Allen.

A study of collections of mayflies belonging imens collected in Arizona and New Mexico, to the family Leptophlebiidae from Arizona, and a comparison of these nymphs with the New Mexico, and Texas in the United States type specimen of C. oaxacaensis reveals that and from Chihuahua, Sonora, and Sinaloa in they belong to a single species and therefore Mexico has revealed new distribution records C. inornata. for species in the genera Choroterpes Eaton, Distribution: This species is now known Lestage, Thraulodes Ul- from southern Mexico (17° N lat.) to southern mer, and Traverella Edmunds.
