Also, Dexosarcophaga lenkoiLopes, 1968, Dexosarcophaga montana (Lopes, 1975), and Dexosarcophaga transitaTownsend, 1917 have their distribution expanded with new records. Dexosarcophaga transita is considered a senior synonym of Dexosarcophaga chaetosaBlanchard, 1939syn. nov., Dexosarcophaga itaquaDodge, 1966syn. nov., and Dexosarcophaga lopesiDodge, 1968syn. nov. With the addition of the new species and the new synonymies proposed, Dexosarcophaga now contains 58 species, of which 10 are recorded in Argentina and 35 in Brazil.
