Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. B. Knight 1941 | Very small, pupaeform gastropods with a thickened outer lip, two apertural teeth, one from the columellar lip and one from the parietal wall, and a notch on the inner side of the upper end of the outer lip; final whorl somewhat distorted and constricted; whorl profile very gently arched; sutures shallow; nucleus unknown; base constricted, narrow, anomphalous but with a slight umbilical depression; free margin of the aperture greatly thickened; columellar lip straight, with a blunt tooth extending a short distance horizontally into the aperture; parietal inductura moderately thin, carrying a lamellar tooth extending vertically downward into the aperture a short distance; outer lip arched, with a sharp notch in the inner side of the thickened margin close to the parietal contact; ornamentation very fine, transverse lirae; shell seemingly rather thick, its structure unknown. The holotype measures 3.3 mm. in height and 2 mm. in width. | |
| R. L. Batten 1995 | Pupaeform shells without ornament, or with reduced ornament. Early whorls very low spired, almost planispiral. Whorl profile evenly inflated with ill-defined periphery low on whorl. Sutures sharply defined and deep. Whorls embrace just below periphery. Ornament, if present, is growth lines alone. Axial translation rate slows with growth, producing a pupaeform shell. Anomphalus. Base is rounded. Aperture is subquadrate with a broad siphonal notch at junction of lower and columellar lips. Low, rounded columellar fold just above notch. Large bladelike fold at junction ofcolumellar lip and parietal surface, which projects at 90˚ to surface into aperture and perpendicular to coiling direction of shell. |
