Euhadra is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the subfamily Bradybaeninae of the family Camaenidae.

(This snail genus was previously placed in the family Eulotidae).

A few of the species in this genus are unusual in that specimens in those species always have left-handed "sinistral" coiling in their shells, as shown in the specimen on the right. The rest of the species in the genus are right-handed or "dextral" in the shell coiling, as is usually the case in the great majority of gastropods.

Distribution

These snails are almost endemic to Japan, but one of them are distributed in Korea.

Species

Most species in this genus have a dextral shell and 5 species are sinistral.

Dextral species

Dextral species in the genus Euhadra include:

Sinistral species
