Restoring the species status of Catharus maculatus (Aves: Turdidae), a secretive Andean thrush, with a critique of the yardstick approach to species delimitation

Abstract
In the 1850s, two species of "Spotted" Nightingale-Thrush (Aves: Catharus) were independently described from montane rainforests of Guatemala, C. dryas (Gould, 1855) and Ecuador, C. maculatus (Sclater, 1858). However, due to similarities in plumage color, C. maculatus was reclassified as a subspecies of C. dryas in 1878, a decision that has been upheld for 137 years. We collected multiple lines of evidence including phylogenetic analysis of mitochondrial DNA sequences (ND2), discriminant and principal components analysis of morphometric and vocal data, and statistical modeling of ecological niches, that collectively indicate that C. d. dryas and C. d. maculatus are independent species. We recommend restoring species status to C. maculatus of South America and applying the common name Sclater’s Nightingale-Thrush to this species.

Mark, do you mean it´s not, like in my notes; "Seebohm, 1887" ... as of here or here?The name Merula subalaris 1887 author is Paul Leverkuhn. ...

Abstract:
Dusky thrush complex comprises of two sister species breeding in SC Siberia, which is the member of thrush Turdus from Turdidae. The phylogenetic resolution of Dusky thrush complex remains controversial, and a detailed research is still necessary. In this research, we determined the complete mtDNAs of both species, and estimated phylogenetic trees based on the mtDNA alignment of these and 21 other Turdidae species, to clarify the taxa status of the Dusky thrush complex. The squenced lengths of these three mitochondrial genomes were 16,737, 16,788 and 16,750 bp. The mtDNAs are circular molecules, containing the 37 typical genes, with an identical gene order and arrangement as those of other Turdidae. The ATG and TAA, respectively, are observed the most commonly start and stop codon. Most of the tRNA could be folded into the canonical cloverleaf secondary structure except for tRNASer (AGY) and tRNALeu (CUN), which lose ‘DHU’ arm. The control region presented a higher A + T content than the average value for the whole mitogenome. The phylogenetic trees reconstructed by the concatenated nucleotide sequences of mtDNA genes (Cyt b, ND2 and COI) indicate the Dusky thrush complex cannot be divided into two species, but the relationships between Dusky thrush subspecies still need additional study. This study improves our understanding of mitogenomic structure and evolution of the Dusky thrush complex, which can provide further insights into our understanding of phylogeny and taxonomy in Turdidae.
The results are also supported by the neighbour-joining tree which constructed based on protein-coding genes Cyt b, ND2 and COI genes (Figure 2). The NJ tree supports that Turdus eunomus and the intermediate have closer genetic relationship than Turdus naumanni, but the Dusky thrush complex probably cannot divided into two species. We suggest that Turdus eunomus and Turdus naumanni should be treated as two subspecies that is Turdus naumanni naumanni and Turdus naumanni eunomus.

I'm intrigued by the ''Turdus intermediate"
So too strong conclusions from a relatively weak dataset? You would never get a species split based on only mitochondrial DNA, so why should you get lumping from only that?
