Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. S. Peel 2016 | Species of Meekospira with a narrow subsutural notch in the outer lip and in which the final whorl in large specimens is expanded in width relative to earlier whorls.
The final whorl is expanded, wider, and shouldered, relative to the whorls of the spire. Protoconch not known. Whorl profile varying from flattened, through uniformly convex to slightly pendant, passing with uniform convexity or slight angularity onto the base. Anomphalous, inner lip slightly reflexed on the smooth columella; aperture lenticular in cross-section, angulated abapically but without an anterior canal; apertural margin with a minute sub-sutural notch. Outer lip varying from straight to shallowly sinusoidal, with slight adapertual convexity below a shallow sinus on the upper whorl surface; convexity enhanced in the more tumid late growth stages of larger specimens. Ornamentation of fine comarginal growth lines only. |
