Oligosphaeridium dispare

"Oligosphaeridium? dispare" (Tasch in Tasch et al., 1964, p.195, pl.2, fig.8) Davey and Williams, 1969, p.5.

TYPE: Holotype: Tasch et al., 1964, pl.2, fig.8.

HISTORY: Originally Hystrichosphaeridium, subsequently Oligosphaeridium?. Questionable assignment: Davey and Williams (1969, p.5).

SYNONYM(S): Taxonomic senior synonym: Hystrichosphaeridium (as Oligosphaeridium) albertense, by implication in Stover and Evitt (1978, p.69), who considered Hystrichosphaeridium (as Oligosphaeridium) dispare to be a taxonomic junior synonym of Hystrichosphaeridium (subsequently Oligosphaeridium) irregulare, which is now a taxonomic junior synonym of Hystrichosphaeridium (now Oligosphaeridium) albertense.

COMMENTS: This combination, as a questionable assignment, was not validly published in Davey and Williams (1966b, p.77), since these authors did not fully reference the basionym.

AGE: Albian.
