Case 3658 Calyptorhynchus baudinii Lear, 1832 (Aves, cacatuida): proposed conservation of usage by designation of a neotype

Abstract. The purpose of this application, under Article 75.6 of the Code, is to conserve prevailing usage of the species names Calyptorhynchus baudinii Lear, 1832 and Calyptorhynchus latirostris Carnaby, 1948, long established for two endemic cockatoos in southwestern Australia (Lear, 1832). The whereabouts of the holotype of C. baudinii Lear, 1832 (Baudin's Cockatoo) was previously unknown and the identity of Lear's (1832) figure was established by Saunders (1974). The holotype has been located at the National Museums Liverpool in December 2010 and found to be conspecific with C. latirostris Carnaby, 1948 (Carnaby's Cockatoo). The resulting nomenclatural shift would destabilise the long established usage of these names and confound past and future references to the names in the literature. To conserve the long established use of baudinii Lear for the distinct long-billed, Baudin's Cockatoo, and to maintain latirostris Carnaby as the valid name for Carnaby's Cockatoo we propose that the type of baudinii ...
