Psittinus Blyth

Type species: Psittacus malaccensis Latham = Psittacus cyanurus J. R. Forster

Morphology/distribution: red bend of wing and red underwing coverts; small size, very short tail; sexually dichromatic; yellow edging on wing coverts; males with bluish head, otherwise predominantly green head; red upper mandible, females with brown head and bill. Distribution: Malay Peninsula to Borneo and Sumatra.

Psittinus , which is represented by nominate cyanurus in our dataset, is sister to a clade formed by Tanygnathus , Belocercus and Psittacula s.s. It represents a long branch within the Psittacula s.l. group, which together with its distinct morphological traits supports its status as a separate genus.
