Smallest to largest - 3 taxa sorted by maximum length
Species within the genus Envekadea are naviculoid, with a sigmoid raphe. The areolae are large and composed of rectangular to irregular polygons. Externally, the areolae are occluded by hymenes. The copulae are unoramented. A single chloropolast is present, which is H-shaped in valve view. Envekadea includes the former Navicula hedinii Hustedt and N. pseudocrassirostris Hustedt.
Envekadea species have been documented from marine and coastal waters (Foged 1984, Lange and Tiffany 2002, Lee et al. 2013), as well as from inland, saline springs (Kaczmarka and Rushforth 1983).
