Taxonomic notes
CAS: "Four species are originally included, and no type is unequivocally designated. A larger treatment is given by Grunow to C. perrotetii which is given as the holotype by Ross in Farr et al. 1979. SVL does not accept this genus: Genus based on monstrosities, vide Pfitzer 1871, p.104-105 (ref. 000754). Hanna (unpubl. ms.) remarked that Cox (Am. Journ. Micr. Pop. Sci. vol. 4, 1879, pp. 97-100) stated that the genus is Stictodesmus Greville and possibly Climaconeis Grunow. He added that all are abnormal forms of Navicula and that C. ehrenbergii of Grunow is N. cuspidata." - (21 Oct 2011) - M.D. Guiry

Comments: Round, Crawford & Mann (1990: 128) record this family as being a member of the Suborder Naviculineae.

Numbers of names and species: There are 62 species names in the database at present, as well as 13 infraspecific names. Of the species names, 61 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..

Names: ('C' indicates a name that is accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.
