SPECIES OF CRENOTIA ARE NOT KNOWN TO OCCUR IN NORTH AMERICA (YET)
The frustules of Crenotia
are heterovalvar, with slightly to strongly concave raphe valve (hypovalve) and convex rapheless valve (epivalve). The valves are lanceolate, linear-lanceolate, elliptic-lanceolate and the small cells are elliptic. Some species have a gibbous...
