Description
The length of the shell attains 2.5 mm, its diameter 1.3 mm.
(Original description in German) The shell is small and conical, terminating in a blunt apex; it is frequently encrusted with a coating of brown silt. There are five whorls that are fairly convex and separated by deep sutures. These whorls increase in size at a moderate pace, with the body whorl occupying slightly less than one-third of the total shell height.
The aperture is ovate, angled slightly toward the right, and tapers to a point at the top. The peristome (apertural margin) is sharp, not expanded, and continuous. Finally, the shell is "perforate", possessing a tiny, slit-like umbilical opening.[5]
Taxonomy
In 2012 Boeters and Knebelsberger proposed the following taxonomic classification for B. conica based on genetic analyses:[6]
Distribution
This species occurs in Germany and Austria.
