Klug, 2001, p.501, Diagnosis: Gyroceratites with a platyconic conch (ww/dm = 0.2). Subcircular to elliptical whorl cross section with flattened venter and ventrolateral edges. The umbilical window is large (1.6 to 2 mm). High whorl expansion rate (2.3 to 2.5 at dm = 10 to 20 mm). The sculpture consists of prorsiradiate concavo-convex growth lines. Suture line with a shallow, sometimes absent external lobe, a shallow and wide lateral lobe.
