"PLANINOSPHAERIDIUM" Eisenack, 1965b, p.151. Taxonomic senior synonym: Pentadinium, according to Stover and Evitt (1978, p.179–180). Taxonomic junior synonym: Ataxiodinium, by implication in Wall et al. (1977, p.149), who transferred the "type species" of Ataxiodinium, Ataxiodinium choane, to Planinosphaeridium — however, Edwards and Andrle (1992, p.265) retained Ataxiodinium. Type: Eisenack, 1965b, pl.14, fig.4; text-fig.1, as Planinosphaeridium membranaceum.
