On the Ethiopian fruit-flies of the genus Dacus

Abstract

The rather numerous Ethiopian species of Dacus (s.l.) are very homogeneousowing to their reduced chaetotaxy and the very simple pattern of the wings; they have no praescutellar bristles, only a scutellar pair, and very often only twosupra-alar bristles, the anterior one being wanting. There are no species with astalked abdomen, or with spinose femora, or with elongated antennae, or withbanded wings.
