Genus Planctonites

Planctonites Krutzsch in Krutzsch et al., 1960, p.141.

SYNONYM(S): Taxonomic junior synonym: Deflandridium, according to Head (1992, p.249).

COMMENTS: Zygnematalean genus (Head, 1992, p.249). Fensome et al. (1990, p.395) were incorrect in stating that this name was not validly published in Krutzsch et al. (1960) since the "type species" had a valid name, Sporites stellarius, even though the combination Planctonites stellarius was not validly published.

TYPE: not designated; "type species" - Sporites stellarius Potonié, 1934.
