Remarks on the subfamily Trochamminellinae Bronnimann, Zaninetti and Whittaker (Protista: Foraminiferida)

Abstract

The genera Ammoglobigerinoides Frerichs, 1969 and Pseudotrochammina Frerichs, 1969, both originally descri­bed from deep waters of the Gulf of Mexico, are distinct and valid taxa belonging to the trochamminacean subfamily Trochamminellinae Briinnimann, Zaninetti and Whittaker, 1983. Atlantiella Saidova, 1981 is a junior synonym of Pseudotrochammina and, therefore, suppressed.
The genus Sepetibaella Briinnimann and Dias Brito, 1982, from shallow waters of the Brazilian Shelf, is transferred to the trochamminacean subfamily Bykoviellinae Loeblich and Tappan, 1984. The definition of the subfamily Trochamminellinae, as originally defined in 1983, is maintained contrary to the emendation of Loeblich and Tappan, 1985.
