Phlebotomus oliverioi Barretto & Coutinho, 1941 foi originalmente descrita baseada em um único macho e desde então tem sido considerada sinônimo-júnior de Psathyromyia brasiliensis (Costa Lima, 1932). O estudo do holótipo de Ph. oliverioi nos levou a concluir que a cabeça deste espécime pertence ao gênero Psychodopygus e as asas, tórax e abdômen pertencem a Psathyromyia. Psathyromyia oliverioi não é uma espécie válida e deve ser removida da sinonímia e excluída de acordo com o recomendado pelo Código Internacional de Nomenclatura Zoológica (Artigos 17.2 e 23.8). O espécime foi medido, desenhado e fotografado e os caracteres morfológicos são discutidos. Lectótipo e paralectótipos são designados para Pa. brasiliensis.

Phlebotomus oliverioi Barretto & Coutinho, 1941 was originally described based only on the male holotype and has since been considered junior-synonym of Psathyromyia brasiliensis (Costa Lima, 1932). The study of the holotype of Ph. oliverioi allowed us to conclude that the head of this specimen belongs to the genus Psychodopygus and the wings, thorax and abdomen belong to a different species of Psathyromyia. Thus, Ph. oliverioi is a not valid species, and must be removed from the synonym and excluded from the provisions of the International Code of Zoological Nomenclature (Articles 17.2 and 23.8). The specimen was measured, drawn, photographed and the morphological characters are discussed. Lectotype and paralectotypes to Pa. brasiliensis are designated.

The phlebotomine sand fly fauna of the State of Minas Gerais is presented based on an extensive review of the literature. The fauna, which is a rich one, is currently known to consist of at least 93 species included in 16 genera. The genus Evandromyia (16 spp.) is the most representative one, followed by Micropygomyia (13 spp.), Psathyromyia (12 spp.), Brumptomyia (11 spp.), Pintomyia (9 spp.), Lutzomyia (7 spp.), Psychodopygus (7 spp.), Martinsmyia (4 spp.), Nyssomyia (3 spp.), Deanemyia (2 spp.), Expapillata (2 spp.), Pressatia (2 spp.), and Sciopemyia (2 spp.). The genera Bichromomyia, Trichopygomyia, and Migonemyia are represented by only one species. An updated list of phlebotomine sand fly species occurring in Minas Gerais is provided. Finally, the importance of the species of public health concern is discussed.
