Timing and Pattern of Early Diversification in Drosophilidae (Diptera).

ABSTRACT: Despite their relevance as model organisms, the early diversification patterns in Drosophilidae remain poorly resolved, with most studies focusing on Drosophila. Here, we employed a phylogenomic framework for 33 taxa: 27 drosophilid species representing most tribes of both subfamilies (Drosophilinae and Steganinae) plus 6 taxa from other families of Ephydroidea (Braulidae, Cryptochetidae, Curtonotidae, and Ephydridae). Besides inferring phylogenetic relationships, we estimated divergence times and substitution rates using a fossil-calibrated Bayesian approach. Our results recover Drosophilinae as monophyletic (among the taxa sampled) but place Braula coeca (Braulidae) within Steganinae, rendering Drosophilidae nonmonophyletic and underscoring the need for taxonomic revision.
