Shell description


For terms see gastropod shell.


The shell is about 2 to 3 millimeters wide, with 6 whorls and shallow sutures. The apex is blunt. The penultimate whorl is striated with 15 to 23 lines and the aperture climbs only slightly at the penultimate whorl. The apertural margin is not thickened inside, the callus does not cover the umbilicus, the angularis is very weak, the parietal callus is weak or absent, no cervical callus is present. There is a minute translucent operculum. The surface is smooth, glossy, reddish to yellowish-brown.



Habitat


This species lives in wet moss and leaf litter in woodlands on calcareous soils. Because it is minute, it is easily overlooked.
