  <dc:description>&lt;p&gt;&lt;span&gt;The Neotropical catfish genus&amp;nbsp;&lt;/span&gt;&lt;i&gt;Tympanopleura&lt;/i&gt;&lt;span&gt;, previously synonymized within&amp;nbsp;&lt;/span&gt;&lt;i&gt;Ageneiosus&lt;/i&gt;&lt;span&gt;, is revalidated and included species are reviewed. Six species are recognized, two of which are described as new.&amp;nbsp;&lt;/span&gt;&lt;i&gt;Tympanopleura&lt;/i&gt;&lt;span&gt;&amp;nbsp;is distinguished from&amp;nbsp;&lt;/span&gt;&lt;i&gt;Ageneiosus&lt;/i&gt;&lt;span&gt;&amp;nbsp;by having an enlarged gas bladder not strongly encapsulated in bone; a prominent pseudotympanum consisting of an area on the side of the body devoid of epaxial musculature where the gas bladder contacts the internal coelomic wall; short, blunt head without greatly elongated jaws; and smaller adult body size. Species of&amp;nbsp;&lt;/span&gt;&lt;i&gt;Tympanopleura&lt;/i&gt;&lt;span&gt;&amp;nbsp;are distinguished from each other on the basis of unique meristic, morphometric, and pigmentation differences.&amp;nbsp;&lt;/span&gt;&lt;i&gt;Ageneiosus melanopogon&lt;/i&gt;&lt;span&gt;&amp;nbsp;and&amp;nbsp;&lt;/span&gt;&lt;i&gt;Tympanopleura nigricollis&lt;/i&gt;&lt;span&gt;&amp;nbsp;are junior synonyms of&lt;/span&gt;&lt;i&gt;Tympanopleura atronasus&lt;/i&gt;&lt;span&gt;.&amp;nbsp;&lt;/span&gt;&lt;i&gt;Tympanopleura alta&lt;/i&gt;&lt;span&gt;&amp;nbsp;is a junior synonym of&amp;nbsp;&lt;/span&gt;&lt;i&gt;Tympanopleura brevis&lt;/i&gt;&lt;span&gt;. A lectotype is designated for&amp;nbsp;&lt;/span&gt;&lt;i&gt;T&lt;/i&gt;&lt;span&gt;.&amp;nbsp;&lt;/span&gt;&lt;i&gt;brevis&lt;/i&gt;&lt;span&gt;.&amp;nbsp;&lt;/span&gt;&lt;i&gt;Ageneiosus madeirensis&lt;/i&gt;&lt;span&gt;&amp;nbsp;is a junior synonym of&amp;nbsp;&lt;/span&gt;&lt;i&gt;Tympanopleura rondoni&lt;/i&gt;&lt;span&gt;.&amp;nbsp;&lt;/span&gt;&lt;i&gt;Tympanopleura atronasus&lt;/i&gt;&lt;span&gt;,&amp;nbsp;&lt;/span&gt;&lt;i&gt;T&lt;/i&gt;&lt;span&gt;.&amp;nbsp;&lt;/span&gt;&lt;i&gt;brevis&lt;/i&gt;&lt;span&gt;,&amp;nbsp;&lt;/span&gt;&lt;i&gt;T&lt;/i&gt;&lt;span&gt;.&amp;nbsp;&lt;/span&gt;&lt;i&gt;longipinna&lt;/i&gt;&lt;span&gt;, and&amp;nbsp;&lt;/span&gt;&lt;i&gt;T&lt;/i&gt;&lt;span&gt;.&amp;nbsp;&lt;/span&gt;&lt;i&gt;rondoni&lt;/i&gt;&lt;span&gt;&amp;nbsp;are relatively widespread in the middle and upper Amazon River basin.&amp;nbsp;&lt;/span&gt;&lt;i&gt;Tympanopleura cryptica&lt;/i&gt;&lt;span&gt;&amp;nbsp;is described from relatively few specimens collected in the upper portion of the Amazon River basin in Peru and the middle portion of that basin in Brazil.&amp;nbsp;&lt;/span&gt;&lt;i&gt;Tympanopleura piperata&lt;/i&gt;&lt;span&gt;&amp;nbsp;is distributed in the upper and middle Amazon River basin, as well as in the Essequibo River drainage of Guyana.&lt;/span&gt;&lt;/p&gt;</dc:description>
