Mexican mayflies : Inventory additions (Ephemeroptera)

Abstract

The 138 species and subspecies of Ephemeroptera now known to occur in Mexico, of which 35, approximately 25 %, are endemic, are listed along with distributional annotations. New Mexican records are included for Americabaetis lugoi Waltz and McCafferty, Baetodes velmae Cohen and Allen, Drunella coloradensis (Dodds), Farrodes otiesa Lugo-Ortiz and McCafferty, Plauditus virilis (McDunnough), Tricorythodes fictus Traver, T. texanus Traver, and Varipes lasiobrachius Lugo-Ortiz and McCafferty, the latter of which also constitutes a new continental record for the genus Varipes Lugo-Ortiz and McCafferty in North America. Traverella sallei (Navas), n. comb., is transferred from the genus Thraulus.
