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 (see Streng et al., 2004, p.482 and Elbrächter et al., 2008, p.1300-1301).  Taxonomic senior synonym: Stomiosphaera, according to Reháková and Michalík (1996, p.93 - however, Streng et al. (2004, p.482) retained Orthopithonella.  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
