Review of Alataleberis McKenzie and Warne, 1986 and description of Alatapacifica gen. nov. (Ostracoda, Crustacea) from the Cenozoic of Australasia

Species originally assigned to the pterygocytherine genus Alataleberis by McKenzie & Warne, 1986 are placed here in two genera—Alataleberis sensu stricto and Alatapacifica gen. nov. Alataleberis species possess poorly defined dorsal ridges marked by a few spines in adult specimens and lack a subcentral tubercle. Alatapacifica species possess well-developed and buttressed dorsal ridges and a well-developed subcentral tubercle. Pterygocytherine genera/species groups recognized here from the southwest Pacific region are Alataleberis, Alatapacifica (septarca and robusta species groups), Alatahermanites Whatley & Titterton, 1981 and the velivola species group of Pterygocythereis Blake, 1933.
