A molecular study of the systematics of the Drosophila tripunctata group and the tripunctata radiation

摘要

The Drosophila tripunctata group Sturtevant (1942), with 58 nominal species (Vilela and Bachli, 2000) is one of the most speciose Drosophila groups in the Neotropical region, surpassed only by the Drosophila repleta species group (Vilela, 1992). Despite its ecological and evolutionary importance, the systematics of the tripunctata group has been largely neglected. The few studies done have yielded controversial conclusions. The genus Drosophila contains 15 subgenera (Powell, 1997), of which Drosophila and Sophophora are the most important.
