Species tree inferred in ASTRAL with the 10-G (left) and the phylogenomic (right) datasets. Both datasets recover the Steganinae subfamily as a monophyletic. Local posterior probabilities are shown on nodes. The blue arrow represents a reticulation event between the ancestral lineages of the Drosophilinae and Phortica + Cacoxenus with inheritance probability of 4.5% (inferred from the phylogenomic dataset with PhyloNet)
