Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. Williams 1962 | Subquadrate to transversely semi-oval Glyptomena less than three-quarters as long as wide with a concavo-convex lateral profile, so that the pedicle valves are less than one-third as deep as long; costellae differentially thickened, most commonly spaced at 10 per millimetre antero-medianly, and cancellated by evenly developed, concentric lamellae with modal counts of 9 per millimetre; ventral muscle-scar subcordate, less than one-third as long as the pedicle valve, with a pair of subparallel vascula media emanating from the anterior lobes of the diductor scars; lateral extensions of the notothyrial platform poorly developed, dorsal median septum extending for about one-half of the length of the valve, adductor muscle-field septate. |
