Truncatella ceylanica (L. Pfeiffer, 1857)Truncatella teres (L. Pfeiffer, 1857)Truncatella pellucida (Dohrn, 1860)Truncatella labiosa (Souverbie, 1862)Truncatella semicostulata (Jickeli, 1874) Truncatella marginata is a species of a very small somewhat amphibious land snail with a gill and an operculum, a semi-terrestrial gastropod mollusk or micromollusk in the family Truncatellidae, the truncatella snails or looping snails.

T. marginata was first described in 1855 by German malacologist Heinrich Carl Küster.

[1] T.marginata is found in countries around the Indian Ocean, including Mauritius, Sri Lanka, Borneo, Malaysia.

These tiny snails live in damp habitat (under rotting vegetation) that is very close to the edge of the sea; they can tolerate being washed with saltwater during especially high tides.
