Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. W. M. Jagt 2000 | A medium-sized species with tall, rather short ultimate superomarginals, generally lacking a well-defined narrow border as well as granule pits, but with coarse granules especially on junction between lateral and aboral surface, one or more of which may grow into blunt spines; lateral surface steep and markedly concave centrally; up to six inferomarginals correspond to ultimate superomarginal. Proximal articulation facet concave aborally, occasionally with granules lines along the distinct articulation ridge, which is especially prominent aborally. Inferomarginals have the same ornament on the central area, but narrow border may be better developed. |
