Candidula is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Geomitridae, . the hairy snails and their allies.
The genus is characterized by the presence of a big dart sac, a sac containing an arrow-like structure found on a land snail's reproductive organs.
