(syn. Aprosmictus Ϯ Red-winged Parrot A. erythropterus) Gr. πτιστης ptistēs winnower < πτισσω ptissō to winnow; "Genus PTISTES, Gould. The birds for which I propose the above generic appellation are, in my opinion, sufficiently different in form and colouring to warrant their being separated from Aprosmictus, and formed into a new genus. ... They have a very laboured flight, consequent on the great size of their wings, which has suggested the generic name of Ptistes, i. e. winnower. Sp. 410. PTISTES ERYTHROPTERUS. RED-WINGED LORY.
