Euhadra is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Bradybaenidae. (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
There are 22 species in the genus. 17 species have a dextral shell and 5 species are sinistral.[2]
Dextral species
Dextral species in the genus Euhadra include:
- Euhadra amaliae (Kobelt, 1875)
- Euhadra awaensis
- Euhadra brandtii
- Euhadra callizona
- Euhadra congenita
- Euhadra dixoni (Pilsbry, 1900)
- Euhadra eoa
- Euhadra herklotsi (Martens, 1861)
- Euhadra idzumonis
- Euhadra kunoensis Kuroda in Masuda & Habe, 1989
- Euhadra latispira
- Euhadra latispira yagurai Kuroda & Habe, 1949 [1]
- Euhadra nachicola
- Euhadra nesiotica (Pilsbry,1902)
- Euhadra peliomphala
- Euhadra sadoensis
- Euhadra sandai
- Euhadra senckenbergiana
Sinistral species
Sinistral species in the genus Euhadra include:
- Euhadra decorata
- Euhadra grata
- Euhadra grata echigoensis Murayama, Takizawa & Habe, 1991
- Euhadra murayamai
