Genus Pithonella

Pithonella Lorenz, 1902, p.46.

EMENDATIONS: Bignot and Lezaud, 1964, p.140; Villain, 1977, p.144; Masters and Scott, 1978, p.215.

SYNONYM(S): Taxonomic junior synonym: Pirumella, by implication in Keupp (1981, p.44), who considered the "type species" of Pirumella, Pirumella edithvincentiae, to be a taxonomic junior synonym of Pithonella (now Pirumella) thayeri - however, Lentin and Williams (1993, p.517) retained Pirumella.

COMMENTS: Calcareous dinoflagellate genus. Keupp in Keupp and Mutterlose (1984) included in Pithonella forms of unknown affinity only; forms which are demonstrably dinoflagellates were included in Obliquipithonella and Orthopithonella. However, Willems (1995a, p.61) considered Pithonella to represent calcareous dinoflagellate cysts.

TYPE: not designated; "type species" - Pithonella ovalis.
