Umbraculum mediterraneum

(Lamarck, 1819)
This species name is also known as Umbraculum umbraculum

Fifty years ago it was speculated that only one species of Umbraculum exists throughout the world (that is Umbraculum umbraculum), and this idea has now been proven genetically. So this one must be called Umbraculum umbraculum regardless where it comes from.

The name Umbraculum mediterraneum is no longer valid (that is, it is a junior synonym of Umbraculum umbraculum).
