Diagnosis
ReferenceDiagnosis
R. L. Parsley and R. J. Prokop 2004Modified from Ubaghs (1967). Theca ovoid to nearly circular in profile. Basals of five thick walled, unequally sized plates. Some plates in series variously excerted from basal area. The aboral ends with varying numbers of small platelets form a cluster or a cluster plus individual platelets intercalated along aboral suture lines. Epispires on lower, lateral, and upper sutures. Middle circlet of five subpentagonal to subhexagonal lateral plates that are equidimensial to elongate and are the largest elements in the theca. Upper circlet composed of subpentagonal, rather small radial plates. Epispires rimmed by slightly raised narrow ridges and cover most of surface of lateral and radial plates. Brachioles single or split into a pair just above a single brachiole base on lateral and radial plates.
