Most recent taxonomic treatment adopted: Kociolek, J.P. & Spaulding, S.A. (2003). Symmetrical Naviculoid Diatoms. In: Freshwater Algae of North America, Ecology and Classification. (Wehr, J.D. & Sheath, R.G. Eds), pp. 637-654. San Diego: Academic Press.

Nomenclatural notes
CAS: "Name conserved with a conserved type vs. Pinnularia Lindl. & Hutton [Foss.] (nom. rej.) and Stauroptera Ehrenberg 1843 (nom. rej., taxonomic synonym) (see ICBN 1956, p. 201, ref. 006916). Name first introduced in Ehrenberg 1840, p. 213 (ref. 000293) as a subgroup within the genus Navicula, with several species listed in alphabetic order as Navicula (Pinnularia) aspera...etc., no type is designated. The name however was not validly published as a subgenus in Ehrenberg 1840 for lacking a description while including more than one species. In Ehrenberg 1843 (ref. 001183) Pinnularia is treated as a genus, 3 species are listed (P. viridis, P. viridula, P. gastrum) and no type is designated." - (21 Oct 2011) - M.D. Guiry

Comments: Round, Crawford & Mann (1990: 128) record this family as being a member of the Suborder Sellaphorineae. Scott & Thomas (2005: 158) record this genus as being a member of the Family Naviculaceae.

Numbers of names and species: There are 1394 species names in the database at present, as well as 1423 infraspecific names. Of the species names, 758 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.
