Perfil taxonómico: Megachile leachella (Curtis 1828)

"Megachile leachella is a representative of the subgenus Eutricharaea within the genus Megachile. For many years this species was misidentified by European authors as M. argentata (F.). In 1872 Thomson established the subgenus Eutricharaea and designated the putative M. argentata as its type species. This fact was revealed by Hurd (1967). On the basis of type studies of Fabrician Apis argentata he concluded that it was not Megachile argentata as interpretated by European authors, but a North African species of Megachile, belonging to the subgenus Eutricharaea. He designated the lectotype for Apis argentata Fabricius in 1964. For the European so-called M. argentata he pro-posed a valid name - M. leachella Curtis." Romasenko, L. P., and J. Banaszak, 1874
