Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. Hoffmann 2015 | Similar to Ectocentrites, but quickly becomes striate or smooth and more similar to Analytoceras; evolute, whorl section rounded to quadrate; fine to medium, radial to subradial ribs on inner whorls fading to slightly prorsiradiate striae or becoming smooth on outer whorls; 5 to 6 constrictions per whorl throughout growth, associated with parabolae with weak ventrolateral nodes; saddle endings tend to be phylloid (Longridge, Smith, & Tipper, 2008). |
