Abstract

Two new species belonging to the genus Anastrepha, A. mayasp. nov. and A. relictasp. nov., are described. These species are noteworthy because they are closely related to A. tripunctata van der Wulp, an endemic Mexican species currently classified in the cryptostrepha species group, which may be the basal lineage of the genus. These new species come from several tropical Mexican localities and share several taxonomic characters found only in A. tripunctata. The eight known species of the cryptostrepha group are keyed, and a discussion of the phylogenetic relationships between this group and other species groups of Anastrepha is presented.

Résumé

Deux nouvelles espèces appartenant au genre Anastrepha, A. mayasp. nov. et A. relictasp. nov., sont décrites. Ces espèces sont remarquables étant donné leur étroite relation avec A. tripunctata van der Wulp, une espèce méxicaine endémique actuellement classée dans le groupe d'espèces cryptostrepha qui a été présumé comme lignée de base du genre. Ces nouvelles espèces proviennent de plusieurs localités tropicales du Méxique, et partagent divers caractères taxonomiques trouvés uniquement dans A. tripunctata. Un code taxonomique pour les huit espèces connues du groupe cryptostrepha, ainsi qu'une discussion au sujet de leurs rapports phylogénétiques avec d'autres groupes d'espèces d'Anastrepha, sont présentés.
