Eatoniella globosa is a species of marine gastropod mollusc in the family Eatoniellidae. It was first described by Winston F. Ponder in 1965. It is endemic to the waters of New Zealand, found in the waters of the upper North Island.
In the original description, Powell described the species as follows:
The holotype of the species measures in height and with a width of . It has a similar but distinct appearance when compared to E. notalabia.
The species was first described by Winston F. Ponder in 1965 as Eatoniella (Dardaniopsis) globosa. In 1995, Hamish Spencer and Richard C. Willan establihed the species' modern name, Eatoniella globosa, removing the subgenus Dardaniopsis. The current accepted name of the species is either Eatoniella globosa, or alternatively Eatoniella (Eatoniella) globosa. The holotype was collected in 1949 by K. Hipkins from Piwhane / Spirits Bay, to the north of the Aupouri Peninsula in the Far North District, New Zealand. It is held in the collections of Auckland War Memorial Museum.
The species is endemic to New Zealand, found in the waters surrounding the north and north-eastern coasts of the North Island. In 2005, a specimen of Eatoniella globosa was found off the coast of Raglan, extending its known range to the west coast of the North Island. Rare specimens have been found in the Tamaki River of Auckland.
Eatoniella globosa has been shown to live almost exclusively on a species of red Corallina seaweed.
