Nomenclatural notes
CAS: "The genus name seems to have first appeared in Ehrenberg 1838 (ref. 006908), p. 176, as "Campylodiscus clypeus (= Cocconeis? clypeus)" but was not validly published (see ICBN 1994 Art. 34.1.d: "a taxon is not validly published by the mere mention of subordinate taxa included in the taxon concerned"). SVL incorrectly gives "Campylodiscus Ehrenberg 1840 (ref. 000293) p. 206" where Campylodiscus clypeus, C. noricus, C. remora, and C. (coronia) echeneis are described; there is however no generic description and it is therefore not validly published in this paper (ICBN 1994, Art 41.2). Kützing 1844 provides the validating generic description, describes 6 Campylodiscus species but does not designate a type. " - (11 Aug 2016) - M.D. Guiry

Numbers of names and species: There are 279 species names in the database at present, as well as 93 infraspecific names. Of the species names, 60 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.
