Phylogenetic Analysis of the Australian Rosella Parrots (Platycercus) Reveals Discordance among Molecules and Plumage
Relationships and species limits among the colourful Australian parrots known as rosellas (Platycercus) are contentious because of poorly understood patterns of parapatry, sympatry and hybridization as well as complex patterns of geographical replacement of phenotypic forms. Two subgenera are, howev...

Relationships and species limits among the colourful Australian parrots known as rosellas (Platycercus) are contentious because of poorly understood patterns of parapatry, sympatry and hybridization as well as complex patterns of geographical replacement of phenotypic forms. Two subgenera are, however, conventionally recognised: Platycercus comprises the blue-cheeked crimson rosella complex (Crimson Rosella P. elegans and Green Rosella P. caledonicus), and Violania contains the remaining four currently recognised species (Pale-headed Rosella P. adscitus, Eastern Rosella P. eximius, Northern Rosella P. venustus, and Western Rosella P. icterotis). We used phylogenetic analysis of ten loci (one mitochondrial, eight autosomal and one z-linked) and several individuals per nominal species primarily to examine relationships within the subgenera, especially the relationships and species limits within Violania. Of these, P. adscitus and P. eximius have long been considered sister species or conspecific due to a morphology-based hybrid zone and an early phylogenetic analysis of mitochondrial DNA restriction fragment length polymorphisms. The multilocus phylogenetic analysis presented here supports an alternative hypothesis aligning P. adscitus and P. venustus as sister species.
