Amphicoelina omphalospira is a species of air-breathing snail in the family Camaenidae. ^[1]

Description

The length of the shell attains 4 mm, its diameter 8.5 mm.

(Original description in French) In contrast to Helicodonta obvoluta (O. F. Müller, 1774), this species exhibits a smaller overall size, a comparatively larger umbilicus, a reduced number of whorls (limited to five), and an aperture that is less subangular, especially in its lower region, which is consistently rounded. Despite a general resemblance to the aforementioned species, it is readily distinguishable by the aforementioned differential features. ^[2]
