CAS: "This genus originally comprised three new species, none of which was unequivocally designated as type. However, only the first of the three species (Falcula rogallii) was presented as "n.gen. n.sp.", whereas the other species were presented as Falcula media n. sp. and Falcula semiundulata n. sp., and it is possible to interpret this typographical differenciation as an indication of the type. This device is often encountered in biological literature and is explicitly accepted as a means of typification by the International Code of Zoological Nomenclature prior to 1931. It is not explicitly ruled unacceptable by the ICBN. Failure to accept Falcula Voigt 1960 as originally typified would mean that it is invalidly published. Later, Voigt 1961 (ref. 001911) describes a fourth species, Falcula paracelsiana (p. 54). If the generic name is not considered valid as of 1960, this fourth species could be considered the type of a monospecific genus in accordance with Art. 42. The situation would be complicated by the fact that Falcula Voigt 1960 was typified with F. rogallii by Greuter et al. 1993 (p. 429), thus creating the later homonym Falcula Voigt ex Greuter et al. 1993 (non Falcula Voigt 1961). Diatom nomenclature seems better served by accepting Falcula Voigt 1960 as a validly published name (P. Silva, pers. com., 1998)." - (21 Oct 2011) - M.D. Guiry
Numbers of names and species: There are 5 species names in the database at present, of which 3 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.
