Harmful species (Lassus et al. 2017). - (19 May 2017) - M.D. Guiry
This is a marine species.
Cells dorso-ventrally flattened, c. 25.7 microns (24.05- 27.35 microns, n = 15) long, c. 24.29 microns (21.79-26.79 microns, n = 15) wide, c 10 microns (n = 1) deep. The hypocone is asymmetrical, with a larger and more rounded right lobe.The apical groove is straight and elevated into an apical crest, extending to the cingulum-sulcus junction on the ventral side of the cell and only a short distance on the dorsal side of the cell. The nucleus is central in the hypocone, but extends somewhat into the epicone. The sulcus extends onto the epicone and flares out to the antapex. The cingulum displaced twice its own width. Chloroplasts are numerous, yellow-green and variable in shape.
Type locality: H.F. Verwoerd Nature Reserve, South Africa (Botes, Sym & Pitcher 2003: 565). Holotype: Fig. 2 (epitype) (Botes, Sym & Pitcher 2003: 565). Notes: Isotype: SEM stub containing specimens of K. cristata (Accession number J 100091) was submitted to the Moss Herbarium, School of Animal, Plant and Environmental Sciences, University of the Witwatersrand, Johannesburg, South Africa.
