Helicina rhodostoma is a species of tropical land snail with an operculum, a terrestrial gastropod mollusc in the family Helicinidae.

In general, populations from higher altitudes have a more pronounced columellar spine, and are more likely to have a red to reddish-orange aperture, as seen in typical Helicina rhodostoma.

[4] Juvenile specimens of this species often have a hairy periostracum, which is gradually worn off as the snail reaches sexual maturity.

[4] Despite the fact that Helicina rhodostoma was originally erroneously described from Guadeloupe – and in subsequent reports from that island the error has been perpetuated – this species is undoubtedly a Dominican endemic.

[4] The fact that no museum material exists labelled “Guadeloupe”, not even in the Muséum national d'histoire naturelle in Paris, indicates that the species has never been collected on that island.
