Description of three new species of Dexosarcophaga (Diptera, Sarcophagidae) from Brazil with new information on synonyms and filling gaps in species distribution

Three new species of Dexosarcophaga are described based on male specimens collected in Brazil, Dexosarcophaga sinoisp. nov., Dexosarcophaga autisferasp. nov., and Dexosarcophaga clavissp. nov. Male morphology is represented by photographs and detailed illustrations of terminalia. Dexosarcophaga carvalhoi (), Dexosarcophaga globulosa, Dexosarcophaga limitata (), Dexosarcophaga paulistana (), and Dexosarcophaga petra are recorded for the first time in Argentina. Also, Dexosarcophaga lenkoi, Dexosarcophaga montana (), and Dexosarcophaga transita have their distribution expanded with new records. Dexosarcophaga transita is considered a senior synonym of Dexosarcophaga chaetosasyn. nov., Dexosarcophaga itaquasyn. nov., and Dexosarcophaga lopesisyn. 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.
