Multilocus analysis of a taxonomically densely sampled dataset reveal extensive non-monophyly in the avian family Locustellidae

► Current classification of avian family Locustellidae strongly disagrees with molecular phylogeny. ► Revised classification, recognizing four instead of seven genera, is proposed. ► Several species-group taxa are in need of further taxonomic work. ► BEST had convergence problems despite up to 1 × 109 iterations.
