Orthopithonella

ORTHOPITHONELLA Keupp in Keupp and Mutterlose, 1984, p.158.  Emendations: Keupp and Versteegh, 1989, p.210; Streng et al., 2002, p.401.  Calcareous dinoflagellate genus.  Taxonomic junior synonym: Stomiosphaera (name not validly published), by implication in Reháková and Michalík (1996, p.93), who believed Stomiosphaera to be the senior name.  Although in proposing this genus Keupp in Keupp and Mutterlose (1984, p.158), did not validly transfer the "type species" to Orthopithonella, the generic name was still valid since it was based on a pre-existing species name.  Type: Bolli, 1974, pl.3, fig.9; pl.12, fig.9; pl.22, fig.3, as Pithonella gustafsonii.

Parent: Subfamily Calciodinelloideae
