Angustopila dominikae is a species of light grey, round, land snails, a terrestrial pulmonate gastropod mollusc in the family Hypselostomatidae.

Angustopila dominikae have been found in southern China, and are considered to be one of the world's smallest terrestrial molluscs (the holotype's shell height is 0.86 mm).

[8] Some unidentified micro-molluscs found in the forests of Argao, Cebu can be smaller in size than Angustopila dominikae, but these species must be further studied before they can stake claim to the title of “Worlds Smallest Snail”.

Jochum, a researcher, hypothesizes that the round shape of the shells of this new species may enable them to wedge themselves into tiny cracks in rocks for further food resources.

[12] It could also allow them to trap air bubbles in their shell and float in water, in case they become dislodged by rain, and also probably enables them to survive being eaten by a predator.
