'''''Zonitoides patuloides''''' is a species of small, air-breathing [[land snail]], a [[terrestrial molluscs|terrestrial]] [[pulmonate]] [[gastropod]] [[mollusk]] in the family [[Gastrodontidae]]. <ref name="WoRMS">MolluscaBase eds. (2023). MolluscaBase. Zonitoides patuloides (Pilsbry, 1895).

==Description==
The altitude of the [[Shell (mollusc)|shell]] attains 2.5&nbsp;mm (0.10&nbsp;in), its diameter 5.1&nbsp;mm (0.20&nbsp;in). 

(Original description) The shell has about the size and form of ''Pyramidula striatella'' <small>(J. G. Anthony, 1840)</small> (synonym of ''[[Discus whitneyi]]'' <small>(Newcomb, 1864)</small> ). It is light green and hardly transparent. The shell is irregularly but closely rib-striate above, below and in the umbilicus. The first 1½ [[Whorl (mollusc)|whorl]]s are smooth. The 4½ whorls are slowly increasing, convex, with impressed sutures. The [[Body whorl|last whorl]] is rather tubular, rounded at periphery and below. The [[Aperture (mollusc)|aperture]] has about the size of the [[Umbilicus (mollusc)|umbilicus]]. It is round-lunate, flattened above. The [[Lip (gastropod)|lip]] is simple. The upper margin is flattened down and arched forward, as in ''Selenites'' or ''Gastrodonta elliotti'' and retracted at insertion. The umbilicus is large, showing all the whorls very plainly.

It is much smaller than ''Gastrodonta elliotti'' Redf., with far larger, open umbilicus and heavier sculpture, recalling a [[Pyramidula (gastropod)|Pyramidula]].<ref> [https://www.biodiversitylibrary.org/page/1731359 Pilsbry, H.

==Distribution==
This species is found on the [[Thunderhead Mountain]] along the border between [[Tennessee]] and [[North Carolina]], USA on mountainsides and ravines on moist leaves.
