Molecular, morphological, and distributional data supporting the recognition of an undescribed freshwater mussel endemic to the Edwards Plateau in the Colorado River basin
May 22, 2023
The widespread distribution of Strophitus undulatus, as well as high intraspecific morphological variation, has led previous authors to doubt the taxon is representative of a single species. Here we provide detailed information for all the freshwater mussels and associated DNA sequence data utilized to test species boundaries in S. undulatus. These molecular data, in combination with morphological data and results from species distribution models, support the recognition of an undescribed freshwater mussel species endemic to streams along the Edwards Plateau in the Colorado River basin in Texas, USA.

Environmental, morphological, and molecular data reveal a new species of freshwater mussel, Strophitus howellsi, endemic to the Edwards Plateau in Texas
Freshwater mussels are considered the most imperiled group of organisms in North America and systematics research has played an integral role in the development and implementation of their conservation. Despite the importance of systematics in conservation planning, the evolutionary relationships between many mussel taxa remain poorly explored, clearly illustrated by Strophitus undulatus. This spe
