Pithonella

PITHONELLA Lorenz, 1902, p.46.  Emendations: Bignot and Lezaud, 1964, p.140; Villain, 1977, p.144; Masters and Scott, 1978, p.215.  Calcareous dinoflagellate genus.  Taxonomic junior synonyms: 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; Palinosphaera, by implication in Zügel (1994, p.17), who transferred the type of that genus to Pithonella - see under Palinosphaera for a full discussion.  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.
