  <dc:description>&lt;p&gt;&lt;span&gt;Major geological processes have shaped biogeographical patterns of riverine biota. The Edwards Plateau of central Texas, USA, exhibits unique aquatic communities and endemism, including several species of freshwater mussels.&amp;nbsp;&lt;/span&gt;&lt;i&gt;Lampsilis bracteata&lt;/i&gt;&lt;span&gt;&amp;nbsp;(Gould, 1855) is endemic to the Edwards Plateau region; however, its phylogenetic relationship with other species in the Gulf coastal rivers and Mississippi River basin is unknown. We evaluated phylogenetic relationships, shell morphologies and soft anatomy characters of&amp;nbsp;&lt;/span&gt;&lt;i&gt;L.&amp;nbsp;bracteata&lt;/i&gt;&lt;span&gt;&amp;nbsp;and a closely related congener,&amp;nbsp;&lt;/span&gt;&lt;i&gt;Lampsilis hydiana&lt;/i&gt;&lt;span&gt;&amp;nbsp;(Lea, 1838) throughout their ranges. Our results showed the presence of an undescribed species:&amp;nbsp;&lt;/span&gt;&lt;i&gt;Lampsilis bergmanni&amp;nbsp;&lt;/i&gt;&lt;strong&gt;sp.n.&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;/strong&gt;&lt;i&gt;Lampsilis bracteata&lt;/i&gt;&lt;span&gt;&amp;nbsp;and&amp;nbsp;&lt;/span&gt;&lt;i&gt;L.&amp;nbsp;bergmanni&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;/i&gt;&lt;strong&gt;sp.n.&lt;/strong&gt;&lt;span&gt;&amp;nbsp;share similar shell morphologies and soft anatomy characters; however, they are genetically distinct. Geological processes, such as faulting and sea‐level changes during the Miocene to Pliocene, are likely to have facilitated diversification of&amp;nbsp;&lt;/span&gt;&lt;i&gt;Lampsilis&lt;/i&gt;&lt;span&gt;&amp;nbsp;species, resulting in isolation of&amp;nbsp;&lt;/span&gt;&lt;i&gt;L.&amp;nbsp;bracteata&lt;/i&gt;&lt;span&gt;&amp;nbsp;on the Edwards Plateau and diversification between&amp;nbsp;&lt;/span&gt;&lt;i&gt;L.&amp;nbsp;bergmanni&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;/i&gt;&lt;strong&gt;sp.n.&lt;/strong&gt;&lt;span&gt;&amp;nbsp;and&amp;nbsp;&lt;/span&gt;&lt;i&gt;L.&amp;nbsp;hydiana&lt;/i&gt;&lt;span&gt;. We conclude that&amp;nbsp;&lt;/span&gt;&lt;i&gt;L.&amp;nbsp;bracteata&lt;/i&gt;&lt;span&gt;&amp;nbsp;range is restricted to the Colorado River basin, whereas&amp;nbsp;&lt;/span&gt;&lt;i&gt;L.&amp;nbsp;bergmanni&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;/i&gt;&lt;strong&gt;sp.n.&lt;/strong&gt;&lt;span&gt;&amp;nbsp;occurs only in upstream reaches of the Guadalupe River basin. Conservation actions are warranted for both species due to their restricted distributions and potential anthropogenic threats.&lt;/span&gt;&lt;/p&gt;</dc:description>
