Zonitoides lateumbilicatus is a species of small, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Gastrodontidae. [1]
The altitude of the shell attains 1.4 mm (0.06 in), its diameter 4.3 mm (0.17 in).
(Original description) The shell resembles Pseudohyalina limatula (synonym of Zonitoides limatulus (A. Binney, 1840)) in color, texture and sculpture, but it is much depressed. The upper surface is almost flat, the last whorl has a much smaller calibre, the umbilicus is very much wider, shallow. And its cavity is widely open and saucer-shaped, much as in Helicodiscus lineatus (Say, 1817) (synonym of Helicodiscus parallelus (Say, 1821)). [2]
This calcifile species is found in eastern Kentucky and northeastern Alabama, USA.
