Assessment of HBW parrot splits

This may be of interest to those who like parrots - our take on the HBW splits for parrots relevant to Colombia is one of a few interesting papers in the latest Conservacion Colombiana:

Pyrrhura snethlageae

The taxonomy of the genus Pyrrhura is still complicated. Latest case is Pyrrhura snethlageae which should be a synonym of Pyrrhura pallescens.

The status of three little known names proposed by Miranda-Ribeiro (1926) and the synonymization of Pyrrhura snethlageae Joseph & Bates, 2002 (Psittaciformes: Psittacidae: Arinae)
RENATO GABAN-LIMA, MARCOS A. RAPOSO

Abstract

The presence of complex geographic variation among species allied to the absence of clear morphological breaks among populations has led to many poorly defined taxa in the genus Pyrrhura (Psittacidae: Arinae: Arini). This article addresses nomenclature of the Pyrrhura picta species complex, particularly the identity of three little-known names introduced by Miranda-Ribeiro (1926): Pyrrhura luciani ochrotis, P. l. pallescens and P. l. melanoides. We show that these names represent subjective synonyms of Pyrrhura snethlageae Joseph & Bates, 2002. Furthermore, we argue that Pyrrhura pallescens (Miranda-Ribeiro, 1926) n. comb. should be considered as the valid senior name because: (1) there is no doubt about the type locality (near the type locality of P. snethlageae) and, as a consequence, it “will best serve stability and universality of nomenclature” as recommended by the International Code of Zoological Nomenclatural, and; (2) it corresponds to the most common phenotype usually referred to as P. snethlageae, the species name that has been used for bird specimens from this region. Those considering P. snethlageae lucida Arndt, 2008 as a valid taxon should refer to this population as Pyrrhura pallescens lucida (Arndt, 2008) n. comb. In a near future P. pallescens melanoides (Miranda-Ribeiro, 1926) n. comb. is likely to be considered the best senior synonym of P. p. lucida given its type locality (Teles Pires River, MT).

Platycercus

Shipham A., Schmidt D.J., Joseph L. & Hughes J.M., 2017. A genomic approach reinforces a hypothesis of mitochondrial capture in eastern Australian rosellas. Auk 134: 181-192.

ABSTRACT
Recently, there have been contradictory results regarding relationships among 3 Australian parrot species known commonly as the Northern (Platycercus venustus), Pale-headed (P. adscitus), and Eastern rosella (P. eximius). An early phylogenetic analysis of the rosella genus Platycercus found that P. adscitus and P. eximius, 2 species putatively forming a hybrid zone, were sister taxa, while the geographically isolated P. venustus was in turn their sister taxon. However, a recent reexamination using multilocus sequence data found that evolutionary relationships differed depending on marker choice. Mitochondrial DNA (mtDNA) supported the earlier finding, but nuclear sequence data reflected an alternative relationship aligning P. adscitus and P. venustus as sister taxa. Two hypotheses were proposed to reconcile the discordance: (1) incomplete lineage sorting, and (2) mtDNA introgression from P. adscitus into populations of P. eximius. To clarify the relationships among these 3 species and to distinguish between the proposed hypotheses, restriction site-associated DNA (RAD) sequencing data from 23 individuals (~4 individuals per subspecies) were examined. Species trees were generated based on datasets either excluding loci with missing data (393 loci) or including them (5 nonoverlapping subsets of 1,000 loci). Findings strongly supported a sister relationship between P. adscitus and P. venustus (posterior probabilities of 1 at all nodes), suggesting that the discordant patterns previously identified may have been the result of mitochondrial introgression and/or capture. This and other potential explanations are discussed.

Psittacula also turns out to be not monophyletic with respect to the genus Tanygnathus, which is nested within the Psittacula radiation, but with only weak bootstrap support.

Mascarin as a descendant from ancestral lineages of the Asian Psittacula eupatria group which dispersed towards the Mascarene islands across the Indian Ocean as suggested earlier (Hume, 2007, Jackson et al., 2015). Taxonomically we suggest to reexamine the delimitation of the genera Mascarinus, Tanygnathus and Psittacula to each other, probably resulting in merging all three to a single genus Psittacula.

It is also interesting that they regarded barkleyi as subspecies of Coracopsys nigra.

Podsiadlowski, Gamauf & Töpfer:

The resulting tree (Figure 2) revealed the position of the Mascarin inside the Psittacula-Tanygnathus clade with a moderate bootstrap support of 80%. The exact position of Mascarin is not well resolved in the tree, but there is weak bootstrap support of 67% for a clade consisting of M. mascarin, the widespread Psittacula eupatria, and of P. wardi, an extinct species formerly found on the Seychelles. Psittacula also turns out to be not monophyletic with respect to the genus Tanygnathus, which is nested within the Psittacula radiation, but with only weak bootstrap support.

I want to be sure that these names are not Nomina Nuda

[pdf] -- Assuming it is actually published (in print, that is -- the .pdf doesn't count without a ZooBank registration), this note made available:
  • Himalayapsitta Braun (in Braun, Bahr & Wink) 2016, type by original designation Psittacus himalayanus Lesson 1831
  • Nicopsitta Braun (in Braun, Bahr & Wink) 2016, type by original designation Palaeornis columboides Vigors 1830
  • Alexandrinus Braun (in Braun, Bahr & Wink) 2016, type by original designation Psittacus krameri Scopoli 1769

(The type fixation that they claim for Palaeornis Vigors [OD] in this note ("Typusart: Psittacus alexandri Linnaeus, 1766 (fehlbestimmt) = Psittacus eupatria Linnaeus, 1766.") is not Code-compliant, however.
- "Psittacus alexandri Linn. 1766" [here] is not an available name distinct from Psittacus alexandri Linn. 1758 [OD], and thus cannot act as a type species. The type is P. alexandri Linnaeus 1758 (= the only available one) by original designation.
- Vigors indeed applied this name to what is now known as Psittacula eupatria, hence his type species was arguably misidentified, and it could in principle be corrected by a published act referring explicitly to Art. 70.3 of the present Code; but, so far, this has not been done (and confirming P. alexandri Linn. as the type under 70.3 would also be possible, in which case the correction would never happen).
Incidentally, the "Psittacus alexandri" that Cuvier 1798 included in "Les perruches", which are deemed to have formed the base of his Psittacula [OD], was unquestionably a Psittacula eupatria as well; but this name is now on the Official List with P. alexandri Linn. as its type, and that would presumably prevent any further correction.)
