Diconodinium? caulleryi (Deflandre, 1935) Deflandre, 1966

Originally Palaeoperidinium, subsequently Diconodinium, thirdly (and now) Diconodinium?.
This species was questionably retained in Diconodinium by Morgan, 1977.

The name Palaeoperidinium caulleryi was not validly published in Deflandre (1935) since the generic name Palaeoperidinium was not validly published until 1967. The name Diconodinium caulleryi was not validly published in Deflandre (1966, p.4) since no holotype was indicated. A full description of this species was given in Deflandre (1936b, p.177).

Holotype: Deflandre, 1935, pl.6, fig.4
