ABSTRACT
Three new species of Drosophila were found in three locations in the Napo province, Ecuador. The specimens were collected in three altitudes 1,700 m, 2,200 m and 3,362 m. All samples were taken using plastic bottles containing bait (banana pieces previously fermented with yeast). The species belong to the groups: Drosophila mesophragmatica (D. neoamaguana sp. nov. and D. neoyanayuyu sp. nov.), Drosophila canalinea (D. cosanga sp. nov.) and Drosophila saltans (D. neoprosaltans sp. nov.); also D. guacamayos sp. nov. not related to any group of species of Drosophila.
