Also, Mascarinus is embedded in Coracopsis: supp info (Appendices S2, S3).The close phylogenetic relationship and low but detectable nucleotide divergence between the single specimen of the extinct P. eques and the extant P. echo (0.2%) suggest that these island populations had evolutionarily diverged, but the low level of divergence suggests it is likely the populations on Reunion and Mauritius were only divergent at a sub-specific level. Comparable levels of nucleotide divergence are seen between some of the species of Coracopsis black parrots of the Indian Ocean; within this genus values range from 0.28% between the sympatric C. n. libs and C. n. nigra found on Madagascar, and 1.79-4.29% between them and C. sibilans on Grand Comoros and C. barklyi on Seychelles, although recent accounts describe the Madagascan subspecies as a single species and the Grand Comoros and Seychelles forms as separate species (del Hoyo et al. 2014, Jackson et al. submitted).

Our phylogenetic analysis suggests invasive P. krameri found on Mauritius and Seychelles originate from southern Asia and comprise two subspecies, P. k. borealis (introduced on Seychelles) and P. k. manillensis (introduced on Mauritius).

Monotypic genus possibly better merged with Coracopsis; further study required.
