Article: Palaeotaxodont bivalves from the Permian of New Zealand

Fifteen species of palaeotaxodont bivalves are described from the upper Artinskian and Kungurian marine deposits of New Zealand. New species are Nuculopsis imperta, N. oviformis, Quadratonucula asymmetrica, Polidevcia antequadrata, Glyptoleda intricata, G. flexuosa, and G. simplicata. One new genus Nucundata is proposed, with new species N, undata, N. truncata, N. obligua, and N. prolonga. An Australian species Nuculana concinna of Fletcher non Dana is renamed Polidevcia nodulosa sp. nov. The genera Phestia, Polidevcia, Glyptoleda, and Nucundata are referred to the subfamily Polidevciinae within the Nuculanidae.
