Remarks. The variety name obesula was first introduced by Monterosato (1878a) without any description, making it a nomen nudum. Bucquoy (et al 1884) first used this name, and so have made it available. It was later proved to be a synonym of Marshallora adversa ( Montagu, 1803) ( Bouchet 1985) . Lectotype designated by Bouchet (1985).
