Nomenclatural notes
The Catalogue of Diatom Names notes (Dec 2017): "Several species are illustrated in the Atlas (H. Peragallo & M. Peragallo 1899, ref. 001054) on pl. 72, fig. 25-28, but no generic description was provided in association with these illustrations. The validating description was subsequently published, in Part 2 of the Text (H. Peragallo & M. Peragallo 1900, ref. 000733), p. 298. Part II was published between 1899 and 1901 according to Stafleu & Cowan 1983 (ref. 007024); pp. 263, 268 of Part II were published in 1900 according to Farr et al. (1979). The genus name is spelled Pseudo-Nitzchia on p. 298 and Pseudo-Nitzschia on p. 263 and pl. 72. Two species were originally included, Pseudo-nitzschia sicula (Castr.) Perag. (plus var. bicuneata and var. migrans) and Pseudo-Nitzschia seriata (Cleve) Perag. (plus var. fraudulenta); no type was originally designated. Fryxell et al. (1991) (ref. 006796) treated this genus as a section of Nitzschia and typified it with Nitzchia seriata. See also Hasle (1965) (ref. 002452), p. 7, who emended the description of Pseudo-Nitzschia." - (20 Dec 2017) - M.D. Guiry

Numbers of names and species: There are 63 species names in the database at present, as well as 12 infraspecific names. Of the species names, 55 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.
