Lesueurillidae is an extinct family of paleozoic molluscs (gastropods?) with anisostrophically coiled shells of uncertain position (Gastropoda?) (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).
Taxonomy
The taxonomy of the Gastropoda by Bouchet & Rocroi, 2005[2] categorizes Lesueurillidae in the superfamilia Euomphaloidea within the Paleozoic molluscs with anisostrophically coiled shells of uncertain position (Gastropoda?). This family has no subfamilies.

Description
Fossils of family Lesueurillidae has sharp peripheral band and a short notch formed from deep V-shaped sinus.[1] They are similar to Maclurites but they differ in early ontogenesis from them.[1]
