abstract = {Pinnularia is an ecologically important and species-rich genus of freshwater diatoms
(Bacillariophyceae) having considerable variation in frustule morphology. Interspecific evolutionary
relationships were inferred for 36 Pinnularia taxa using a five-locus dataset. A range of fossil taxa,
including newly-discovered Middle Eocene forms of Pinnularia, was used to calibrate a relaxed
molecular clock analysis and investigate the temporal aspects of the genus' diversification. The multigene
approach resulted in a well-resolved phylogeny of three major clades and several subclades that
were frequently, but not universally, delimited by valve morphology. The sister genus Caloneis was not
recovered as monophyletic, confirming that, as currently delimited, this genus is not evolutionarily
meaningful and should be merged with (parts of) Pinnularia. The Pinnularia-Caloneis complex is
estimated to have diverged between the Upper Cretaceous and the early Eocene, implying a ghost
range of at least 10 million year (Ma) in the fossil record.}
