Molecular resources for investigating relationships among freshwater mussels (Bivalvia: Unionoida) with a focus on the genus Alasmidonta

Longstanding taxonomic uncertainties have limited conservation efforts for species currently assigned to the freshwater mussel genus Alasmidonta. Here, we present mitochondrial and nuclear DNA sequence data needed to assess the genus- and species-level taxonomy of Alasmidonta. These molecular data allowed us to test whether cryptic diversity exists within Alasmidonta and whether A. triangulata and A. arcula are distinct species. Details associated with specimens and DNA sequence data are provided here to provide a foundation for future research on Alasmidonta and give conservation agencies greater confidence in the findings of our work.
