Praecalcigonellum

PRAECALCIGONELLUM Keupp and Versteegh, 1989, p.211.  Calcareous dinoflagellate genus (see Streng et al., 2004, p.483 and Elbrächter et al., 2008, p.1301).  Although the "type species", Praecalcigonellum polymorphum, was not validly transferred by Keupp and Versteegh (1989, p.211), the generic name Praecalcigonellum was validly published by these authors since it is based on a previously validly published species name (I.C.N. Article 40.3).  Type: Keupp, 1980a, pl.15, figs.7–8, as Calcigonellum polymorphum.

Parent: Subfamily Calciodinelloideae
