Eatoniella latebricola is a species of marine gastropod mollusc in the family Eatoniellidae. It was first described by Winston Ponder in 1965. It is endemic to New Zealand, typically found in the waters of the northern North Island, in association with Durvillaea (southern bull kelp).
In the original description, Ponder described the species as follows:
E. latebricola measures by . It can be identified due to its shell being broadly conical, yellowish-white, smooth, semi-transparent, solid, and by its white, D-shaped aperture.
The species was first described by Winston Ponder in 1965, who used the name Eatoniella (Dardanula) latebricola. The modern formatting of the name without a subgenus, Eatoniella albocolumella, was established by Hamish Spencer and Richard C. Willan in 1995. The holotype of the species was collected by Ponder himself on 19 August 1963, under Durvillaea at the southern end of Muriwai on the west coast of the Auckland Region, New Zealand. It is held by the Auckland War Memorial Museum.
The species is endemic to New Zealand, found in the waters of the North Island, typically in the Northland Region, the Auckland Region (as far south as Piha to the west and Cape Rodney on the east coast), Cuvier Island in the Waikato Region northeast of the Coromandel Peninsula, around ManawatÃÂwhi / Three Kings Islands, and once on the West Coast of the South Island, near Haast.
E. latebricola typically lives on Durvillea seaweed. In 2003, dead specimens of the species were identified on Cuvier Island where Durvillaea is not present. It was theorised that the species might live on algal holdfasts, such as the kelp species Ecklonia radiata.
