Microdrosophila
vinegar flies
Microdrosophila is a genus of small flies in the family Drosophilidae, commonly known as vinegar flies. The genus was established by Malloch in 1921 and contains at least 70 described species. These flies are part of a diverse family that includes the well-known model organism Drosophila melanogaster, though Microdrosophila species are generally less studied. The genus appears to have a primarily Palearctic distribution based on available occurrence records.
Stegana
vinegar flies
Stegana is a genus of vinegar flies (Drosophilidae) comprising at least 140 described species. The genus is characterized by high morphological conservatism, particularly in the subgenus Orthostegana, where evolutionary stasis has produced numerous cryptic species that are difficult to distinguish by external morphology alone. Species delimitation often requires integrative approaches combining molecular data (mitochondrial COI and ND2 genes) with detailed morphological analysis.
