Review of existing species of fruit flies in Ecuador

This study was carried out since 1990 to 1997. The goal was to figure out different species of fruit fly that inhabit in Ecuador. For the identification we put special emphasis in the female genitalia. We recommend to do more research into this subject, because of the few studies done in our country and the importance of fruit cultivation. We mention 32 genus in the family Tephritidae in Ecuador, including the introduced genus Ceratitis. Into Toxotrypaninae are pointing out the presence of one specie of the Toxotrypana genus and 31 species of the Anastrepha genus, detailing brilly the 27 species most common. General notions about taxonomic bases are mentioned in order to identify species of the Anastrepha Schiner, pointing out certain fenotipic characteristics that prove variability among the ecuadorian's population, mainly A. fraterculus, A. distincta, A. obliqua, A. striata, and others.
