What is "zaprionus"

The genus Zaprionus belongs to the family fruit fly Drosophilidae and is positioned within the paraphyletic genus Drosophila. All species are easily recognized by the white longitudinal stripes across the head and thorax. The genus is subdivided in two subgenera, based on the presence of an even (subgenus Zaprionus) or odd (subgenus Anaprionus) number of white stripes. The species of the genus can be found in African and Southern Asia. One species, Zaprionus indianus, has invaded the New World.
