Description: Cells solitary or in short chains, rectangular in girdle view; plastids not observed. Valves elliptical to rhomboid-lanceolate in valve view. Valve face with short, uniseriate striae composed of large areolae occuled by vola-type cribrum; lanceolate sternum wide with a distinct central stauros; apical slit fields, composed of longitudinal slits and lamellae that do not extend to the mantle, not visible with light microscope. Rimoportulae and spines not observed. Cingulum composed of 2-3 open copulae, the valvocopula with median rudimentary septa; copulae hyaline, lacking ligulae. The central stauros, apical slit fields, vola-type occlusions on the areolae and rudimentary septa on the valvocopula serve to distinguish Desikaneis from Fragilaria. The type species has been reported from the marine and brackish-water plankton in the Gulf of Mexico and off the coast of Venezuela.

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
