Brief SummaryRead full entry
Zaprionus Coquillett, 1902 is a drosophilid genus characterized by the presence of longitudinal white stripes on the frons and the mesonotum. These stripes are structural, consisting of long grooved trichomes that reflect the light. It is a Paleotropical genus whose species are classified under two subgenera: Zaprionus in the Afrotropical region (50 spp.), and Anaprionus in the Oriental and Australasian regions (12 spp.). Recently, two of its Afrotropical species became invasive, namely Zaprionus indianus Gupta, 1972 and Zaprionus tuberculatus Malloch, 1932, with cosmopolitan and subcosmopolitan distributions, respectively. In Tropical Africa, most species breed on ripe fruits but some are flower breeders. Phyogenetic analyses show the genus to be polyphyletic, with some species of the subgenus Anaprionus being more related to other drosophilid genera than to the subgenus Zaprionus.
