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.
Species:
DINOFLAJ (c) 1998
