Thoracosphaera

THORACOSPHAERA Kamptner, 1927, p.180-184.  Emendation: Fütterer, 1976, p.119,130 - see below.  Extant calcareous dinoflagellate genus.  According to Tangen et al. (1982), the "type species", Thoracosphaera heimii, represents the calcareous cell wall of a dinoflagellate vegetative stage.  It is unlikely, however, that all the species listed below are dinoflagellates.  Fütterer (1976) provided a diagnosis for Thoracosphaera which was not labelled an emendation or revision; in his abstract, however, he refers to the "redefined and revised genus Thoracosphaera".  Type: Kamptner, 1927, text-fig.6, as Syracosphaera pelagica.
