(Described as Isthmia corpulenta) The shell is rimate perforate, elongate ovate, finely striated, polished, translucent, dark olive brown. The apex is round and obtuse. The shell contains four whorls, convex, tumid, wider at the base. The aperture is large, subcircular, with four obtuse teeth, one on the parietal margin, one on the columellar margin, and two on the outer lip. The peristome is slightly thickened and reflected.[2]
