Original diagnosis:

"A fairly thick-walled, distinctly bi-layered, proximo-cavate dinoflagellate cyst species with smooth endo- and periphragm. The body layers are appressed except in an area including the paracingulum and those portions of the pre- and postcingular series adjacent to it. Paratabulation of the formula 3', ?6'' ?6c, 5''', 1p.v., 1'''' is outlined by low parasutural crests. Gonal areas bear short, trifurcate processes and, rarely, bifurcate parasutural ones may be present. The archeopyle is single-paraplate precingular (3'')." - From Duxbury (1983, p. 57-58).
