Comprehensive molecular phylogeny of the grassbirds and allies (Locustellidae) reveals extensive non-monophyly of traditional genera, and a proposal for a new classification.

•Phylogeny of avian family Locustellidae based on multilocus data for all except 3 of the species.•Exceedingly high level of disagreement with current taxonomy due to complex morphologivcal evolution.•Revised taxonomy proposed.•One new genus described.•Species diversity probably underestimated as indicated by multiple deep intraspecific divergences.
