Resumen:
The study contributes to the knowledge of the morphological diversity within theChrysosarus lineage, one of the largest subgenera of Megachile in theNeotropics. The species of the leucografa group share characteristics withother groups of Megachile which have been placed until recently in differentsubgenera, such as Dactylomegachile Mitchell and Chrysosarus Michell. Speciesincluded are Megachile leucografa Friese, M. obscurior Jörgensen and M.rancaguensis Friese. The last two species have not been properly recognizedsince their description early in the 20th century. Diagnoses, redescriptions,study of type material, distributions, and illustrations are presented.
