Three new species of Munidopsis (M. amapa and M. brasilia from Brazil, and M. bajacalifornia from California and the Galápagos Islands) are described. All are small, superficially similar to each other and from shallower depths than is typical of most of the genus. All species have a highly sculptured carapace, triangular rostrum and immovable eyestalks with prominent anterior eyespines.
