Remarks.

It was described under the name Paludestrina nigra d’Orbigny, 1840 for the north of Chile. Afterwards, Marincovich (1973) described the species Eatoniella latina being the first representative Eatoniellidae for the Southeast Pacific. However, Ponder and Worsfold (1994), upon revising the shells of both species, found a common morphology, lower, more ovular, and thinner than the other black-colored species present in South America. Thus, Eatoniella latina is considered a junior synonym of this species. Records from South Africa ( Rosenberg et al. 2002, OBIS 2014) likely correspond to Eatoniella afronigra according to Ponder and Worsfold (1994).

Distribution.

WTSP: Iquique ( Marincovich 1973, Ponder and Worsfold 1994), and Antofagasta ( Ponder and Worsfold 1994). Magellanic: Puerto Montt ( Ponder and Worsfold 1994), Chiloé Archipelago ( Ponder and Worsfold 1994), and Coyhaique ( Ponder and Worsfold 1994); Strait of Magellan: western entrance of the Strait of Magellan ( Ponder and Worsfold 1994) and Punta Santa María (this record); Staten Island ( Ponder and Worsfold 1994).
