N1 - Funding Information:
We thank David Berg, Amy Burden, Michael Hart, Steven Hein, Anna Pieri, and Ned Strenth for sharing specimens and help in the field and laboratory. We especially thank Aaron Koch, Heather Warman, Enrique Aguado, and Charlie Morones from SUP Kentucky and Kayak Huasteca for taking very good care of us while in Mexico. Edna Naranjo assisted with permit acquisition. We thank Eduardo Gonzalez, Enrique Corona, and Pablo Gonzalez at the Universidad Autónoma de Tamaulipas for logistical support and assistance in the field. We thank Chris Harper, Gary Pandolfi, and Susan Oetker (U.S. Fish and Wildlife Service) for funding (F17AC01008); without their support this study could not have happened. Samples were collected under TE79165C-0 (USFWS permit for P. popeii) and SGPA/DGVS/002175/18 (Mexico Popenaias). Thanks also go to Jerry Harasewych for the biographical information on Dan Bereza.

N2 - The Gulf coastal drainages of central Mexico are a faunal transition zone between North and South America and harbor a unique assemblage of freshwater mussels (Bivalvia: Unionida). However, little information is available regarding the taxonomy, distribution, and evolutionary history of the Mexican mussel fauna due to limited sampling over the last 100 years. To address these knowledge gaps, we evaluated species-level diversity in the genus Popenaias Frierson, 1927, in Mexican Gulf coastal drainages as part of a larger effort to inform conservation efforts for members of this genus both in Mexico and the United States of America. Based on our analyses, we describe Popenaias berezai n. sp. from the Río Valles of the Río Pánuco basin, San Luis Potosí, Mexico. We also provide presumptive distributional range, phylogenetic structure, and molecular and morphological diagnoses of the new species and provide comments on the other species currently in Popenaias. Our findings highlight the high levels of endemism among freshwater mussels in Mexican Gulf coastal drainages and will help guide impending conservation actions for P. popeii, which is listed as "endangered"in the United States.
