This section presents a systematic catalogue of Drosophilidae. The Drosophilidae is a large, cosmopolitan family of acalyptrate flies (Diptera, Schizophora). It is one of the most important groups of insects, because it includes the model organism Drosophila melanogaster Meigen, which has been studied intensively by geneticists, developmental biologists and others. With the continuing loss of traditional taxonomic expertise on one hand and the increasing importance of molecular taxonomy and barcoding on the other hand, it is very important to have a solid framework of names as a basis for future research on Drosophilidae.Keywords: acalyptrate flies; Drosophilidae; molecular taxonomy
