Diagnosis
ReferenceDiagnosis
D. F. Wright and A. L. Stigall 2014Similar to G. insculpta but typically smaller (character 1, width 17.40–19.52 mm) and always having ventral muscle scars resting on a raised platform (see Remarks). Shell of moderate to large size for Glyptorthis; outline subquadrate; dorsal valve inflated. Sulcus deep, originating proximal to the umbo. Concentric ornamentation strongly lamellose for species of Glyptorthis. Ventral muscle scars large, width variable, with an anterior deflection. Angle between the lateral boundaries of the ventral interarea >130˚; delthyrial angle high (>55˚).
