Molecular and morphological data on two species complexes in the freshwater mussel genus Cyclonaias

We examined species boundaries within an imperiled group of freshwater mussels in the genus Cyclonaias (Bivalvia: Unionidae) using morphometrics, molecular phylogenetics, and multispecies coalescent models to help guide pending conservation assessments and legislative decisions. Congruence across all lines of evidence indicated that current taxonomy overestimates diversity in the C. pustulosa species complex, while underestimating diversity in the C. petrina species complex. Here we provide all molecular, morphological, and collection information collected and analyzed in our investigation.
