  <dc:description>&lt;p&gt;&lt;span&gt;Light and electron microscope observations show that a brackish diatom taxon should be classified as a new species of a new genus; &lt;/span&gt;&lt;i&gt;Pseudofrustulia lancea gen&lt;/i&gt;&lt;span&gt;.&lt;/span&gt;&lt;i&gt; et sp&lt;/i&gt;&lt;span&gt;.&lt;/span&gt;&lt;i&gt; nov&lt;/i&gt;&lt;span&gt;. We propose separating &lt;/span&gt;&lt;i&gt;Pseudofrustulia&lt;/i&gt;&lt;span&gt; from other similar genera such as &lt;/span&gt;&lt;i&gt;Frickea&lt;/i&gt;&lt;span&gt;,&lt;/span&gt;&lt;i&gt; Frustulia&lt;/i&gt;&lt;span&gt;, &lt;/span&gt;&lt;i&gt;Amphipleura&lt;/i&gt;&lt;span&gt;, &lt;/span&gt;&lt;i&gt;Muelleria&lt;/i&gt;&lt;span&gt;, and &lt;/span&gt;&lt;i&gt;Envekadea &lt;/i&gt;&lt;span&gt;on the basis of its thickened axial ribs, raphe endings, axial costae, morphology of helictoglossa, size of striae on valve surfaces, and areolae on the inner side between its axial ribs and raphe. Girdle bands may be another diagnostic feature for the separation of &lt;/span&gt;&lt;i&gt;Pseudofrustulia&lt;/i&gt;&lt;span&gt; from related taxa, but more detailed observations using SEM images are required to determine if bands are diagnostic.&lt;/span&gt;&lt;/p&gt;</dc:description>
