Euhadra is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the subfamily Bradybaeninae of the family Camaenidae.[2]

(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

[edit]

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

Species

[edit]

Most species in this genus have a dextral shell and 5 species are sinistral.[3]

Dextral species
