Cauveridinium
From Williams et al., 2017:
[Cauveridinium, Khowaja-Ateequzzaman and Jain, 1990, p. 172, 174
Type species: Cauveridinium indicum, Khowaja-Ateequzzaman and Jain, 1990 (pl.1, figs.1–5; text-figs.1A–C)]
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Original description: [Khowaja-Ateequzzaman and Jain, 1990]:
Diagnosis:
Cyst skolochorate, lenticular, subcircular; apex obtusely angular; antapex with two unequal prominences separated by a concavity; autophragm ornamentation elaborate with processes along circumferential border zone but modified on central dorsal and central areas; processes solid or hollow, mostly connected proximally through ridges, rarely distally fused; archaeopyle apical, type (4A), operculum simple, polyplacoid, free.
Affinities:
Dinoflagellate cysts described under a new genus Cauveridinium are, in general, of Cyclonephelium morphology but are distinguished from the latter in characteristic development of ridges connecting the adjacent processes proximally. The other genera of Areoligera complex are compared and differentiated here (Table1).
