In the Yasuni National Park, a place recognized as a hot spot biodiversity, located in the Northwestern Ecuadorian Amazon was made a taxonomic survey of the Drosophilidae. Individuals were collected using traps with banana and yeast as bait. Taxonomic identifications were made by morphologic characters and male genitalia analysis. We collected 7425 individuals of 34 species, from the genera: Drosophila Fallén, 1823, Scaptodrosophila Duda, 1923, Neotanygastrella Duda, 1923 y Zaprionus Coquillett, 1901. Six of them are new records for Ecuador: D. araicas Pavan & Nacrur, 1950, D. equinoxialis Dobzhansky, 1946, D. kikkawai Burla, 1954, D. subsaltans Magalhães, 1956, D. neocordata Magalhães, 1956 and D. peninsularis Patterson & Wheeler, 1942. This data increase the number of species records to Ecuador and the Amazon Region.
