Tjaernoeia is a genus of sea snails in the heterobranch clade Mesoneura.[3] They are named after the marine laboratory at Tjärnö, Strömstad, Sweden. Their shells are rounded, thin and translucent.
Species
[edit]There are four species of Tjaernoeia. Two of them are found in the Bohuslän region of Sweden: Tjaernoeia exquisita and Tjaernoeia unisulcata.[4] Tjaernoeia boucheti can be found in Scandinavia and in Iceland. Tjaernoeia michaeli has been found in Antarctica and Brazil.[5]
It was found in Scottish waters in 1988 (as Tornus exquisitus).
In 2025, Spanish researchers found Tjaernoeia outside the Spanish and Catalan coast of these two types: the lower heterobranch Rhodope salviniplaweni sp. nov. and the nudibranch Embletonia mediterranea sp. nov.[6]
Tjaernoeia is the only genus in the family Tjaernoeiidae.[7] Their closest relatives are Parvaplustridae, with which they are classified in the superfamily Tjaernoeioidea.[3] When the genus Tjaernoeia was first named, for a species previously included in Fossarus, it was tentatively classified in Pyramidellidae.[2]
Species
[edit]Species in the genus Tjaernoeia include:
- Tjaernoeia boucheti Warén, 1991[8] - from deep water in the northeastern Atlantic[1] It has a smooth or almost smooth protoconch.
- Tjaernoeia exquisita (Jeffreys, 1883) - described from Crete,[9] also known from Ghana[10]
- Tjaernoeia michaeli Engl, 2002[11]
- Tjaernoeia unisulcata (Chaster, 1897)[12]
