Burtonia
From Williams et al., 2017:
[Burtonia, Beju, 1983, p. 106 (non Burtonia Brown, 1811)
Name illegitimate. Originally Burtonia Beju, 1983, subsequently Bejuia Stover and Williams, 1987, nom. subst. pro Burtonia, Beju, 1983
Bejuia is a tax. jr. synonym of Atopodinium Drugg, 1978, according to Masure, 1991
Type species: Burtonia polygonalis, Beju, 1983 (text-figs.3A–B,4A–B)]
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Original description: [Beju, 1983]:
Diagnosis:
Proximate dinocysts with subpolygonal outline. Apex flattened to weakly protuberant, displaced on the ventral side; antapex consisting of a prominent protuberance. Cyst single-walled (autophragm). Paratabulation incompletely indicated by low parasutural ridges, well expressed on the hypocyst, where it consists of six postcingular paraplates; an additional paraplate ("shield") is transversely arranged on the ventral antapical margin of the hypocyst. Epicystal paratabulation indeterminable under the light microscope. Paracingulum discernible, especially on the ventral side, helicoidal, displaced in apical direction on the dorsal side. Epicyst considerably smaller than the hypocyst, ventrally displaced. Archeopyle of uncertain type.
