Van de Vijver, Gligora, Hinz, Kralj and Cocquyt 2009      Category: Symmetrical biraphid
TYPE SPECIES: Envekadea hedinii (Hustedt) Van de Vijver et al.




CLASS: Bacillariophyceae
  ORDER: Naviculales

  1. Raphe sigmoid

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 porous 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 pseudocrassirostris (Hustedt) Van de Vijver et al. has been documented from marine and coastal waters (Kaczmarska and Rushforth 1983, Foged 1984, Witkowski et al. 2000, Lange and Tiffany 2002, Procopiak et al. 2006). Other taxa will likely be included in this genus soon.
