Diagnosis
ReferenceDiagnosis
S. Zamora and A. B. Smith 2008A cinctan whose theca is strongly asymmetrical in shape; anterior margin very wide and nearly straight; marginal plates M4r to M6r form an indented, bridge−like structure. Upper tegument of plates (supracentrals) differentiated into two discrete areas, the anterior central area formed of larger plates without pits or pores, the posterior and marginal areas of smaller plates with stellate ornamentation; an arc of small openings is developed towards the left side of the supra-centralia separating these two areas. Long left and very short right marginal grooves, extending from plate M1l to M2r.
Marginal plates M4l and M4r are hatchet−shaped, which becomes especially pronounced in larger individuals.
