Otoconcha is a genus of small air-breathing semi-slugs, terrestrial pulmonate gastropod molluscs in the family Charopidae.

[2] Frederick Wollaston Hutton firstly defined this genus in 1884.

[1] Hutton's diagnosis reads as follows:[1] Shell external, of very few rapidly increasing whorls, all of which are open underneath.

Animal limaciform, much too large to withdraw into the shell; mantle rather anterior, covering the shell; no locomotive disc, nor mucous caudal gland.

Jaw with distant ribs.Species within the genus Otoconcha include: This article incorporates public domain text from the reference[1]
