Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| D. F. Wright and A. L. Stigall 2014 | Large (character 1, width 20.24–25.69 mm) species of Glyptorthis with a subquadrate outline and fine concentric ornamentation weakly to strongly lamellose. Costal density low to moderate (see Online Supplementary Material Tables 2 and 4, character 11); ventral muscle scars large with lateral and anterior deflections; narrowing near the teeth. Ventral diductor scars separated by a medial septum; adductor scars of variable width, widening towards the anterior. Dorsal cardinal area high (character 31, Online Supplementary Material Table 2), extending over the hinge line; umbonal angle less than 150˚. |
