Braun, Michael P., Datzmann, Thomas, Arndt, Thomas, Reinschmidt, Matthias, Schnitker, Heinz, Bahr, Norbert, Sauer-Gürth, Hedwig & Wink, Michael, 2019, A molecular phylogeny of the genus Psittacula sensu lato (Aves: Psittaciformes: Psittacidae: Psittacula, Psittinus, Tanygnathus, † Mascarinus) with taxonomic implications, Zootaxa 4563 (3), pp. 547-562 : 558-559

Psittacula s.s. Cuvier

Type species: Psittacus alexandri Linnaeus

Morphology/distribution: no red shoulder patch; medium to large size; sexual dimorphism; yellow patch on wing coverts in most taxa; males with red upper mandibles; unique grey to bluish head pattern with bold black lores and bold black stripe on lower cheeks. Distribution: Southern Asia to Bali.

Based on high support values, only three other taxa, P. derbiana Fraser, P. a. abbotti Oberholser , and P. a. fasciata Statius Müller , remain in core Psittacula . Based on morphology, P. caniceps Blyth (for details see Arndt 2008; Forshaw 2010), which was not genetically sampled, should also remain in Psittacula s.s. The taxon fasciata is currently treated as a subspecies of P. alexandri , but based on genetic distance and morphology, separate species status should be considered. The taxon abbotti is also in need of further taxonomic investigation. If only monophyletic groups are considered species, P. alexandri should be split into two distinct species: P. alexandri with completely red bill in both sexes and P. fasciata with black bill in females and red upper and black lower mandible in males. Further investigations using more individuals and sampling of all wild populations are needed for deeper insights into the evolutionary history of this species complex.

between the clades alexandri and fasciata / abbotti . CYTB p-distance values are a measure of divergence time (MYA).
