It's too bad Kundu et al. (2011) was accepted so uncritically by TiF.
The authors (Fig. 3 and p. 8) split up the subspecies of Long-tailed Parakeet,
Psittacula longicauda and Red-breasted Parakeet,
P.alexandri and:
- group
longicauda longicauda in a clade with Blue-winged Parakeet,
P. columboides and Layard's Parakeet,
P. calthorpae
- unite
alexandri fasciata in a clade with Lord Derby's Parakeet,
P. derbiana
- unite
alexandri alexandri in a clade with
longicauda tytleri
- and embed Blue-backed Parrot,
Tanygnathus sumatranus in
Psittacula!
These new taxon pairs look nothing like each other, unlike the traditional arrangement. If this study is accepted, it would require the creation of at least 1 new species (
P. fasciata), and
Tanygnathus sumatranus would become
Psittacula sumatrana.
Mascarinus, a monotypic genus comprising the extinct Mascarene Parrot,
M. mascarinus of Réunion, is embedded in
Coracopsis nigra, with
C. n. barklyi of the Seychelles basal to
mascarinus, and
mascarinus basal to
C. n. nigra +
libs +
siblians, indicating that
M. mascarinus is either a subspecies of
C. nigra, or that the
nigra complex comprises 3 species. Neither conclusion is credible, although
barklyi may warrant recognition as a separate species, and it's plausible that
Mascarinus was allied to
Coracopsis.
Having studied extinct birds for 10+ years, I maintain that
Mascarinus was sufficiently distinct from
Coracopsis that it should continue to be recognized as a separate genus. Compared to
Coracopsis,
Mascarinus had a relatively larger, red bill, a red iris and eye-ring, a black facial mask, a light gray head contrasting with a very dark gray (or brownish gray) body, and white bases to the lateral rectrices
Whether
Coracopsis should be listed in the Psittacidae sequence after
Psittrichras, as the authors indicate in Fig. 2, is also debatable, as the clade receives only weak support.
Thankfully, the IOC World List has not accepted the results of this study.
