Cyornis flycatcher (1 Viewer)

A new genus for the White-tailed Flycatcher Cyornis concretus (Aves: Muscicapidae) | Zootaxa

Molecular phylogenetic studies have identified a clade of flycatchers that includes several species in which the males are (mostly) blue (Sangster et al. 2010; Zuccon et al. 2010). This clade was named Niltavinae by Sangster et al. (2016) and includes the genera Anthipes, Cyornis, Niltava, Cyanoptila, Eumyias and Sholicola (sensu Fjeldså et al. 2020). The relationships within Niltavinae have been illuminated in several molecular phylogenetic studies (Sangster et al. 2010; Barve & Mason 2014; Zhang et al. 2016; Robin et al. 2017; Singh et al. 2020). Two of these studies placed White-tailed Flycatcher Cyornis concretus (S. Müller, 1836) as the sister to all other members of Niltavinae (Sangster et al. 2010; Zhang et al. 2016). One study placed White-tailed Flycatcher as the sister to two species of “Myiomela” (= Sholicola) (Barve & Mason 2014), and another placed White-tailed Flycatcher as the sister to Anthipes and Cyornis (Robin et al. 2017). These studies agree that White-tailed Flycatcher is not part of Cyornis. Thus, White-tailed Flycatcher is best placed in a separate, monotypic genus. The type species of Cyornis is C. rubeculoides (Vigors, 1831). No previous genus name appears to have been published for C. concretus and we therefore propose:

Leucoptilon gen. nov.
Type species : Muscicapa concreta Müller, 1836.

Leucoptilon concretum comb.nov.

lol, I helped write this article and I don't even have a copy 🤣

Jimmy, can you send me this article too?

IOC Updates Diary:

Dec 3 Move White-tailed Flycatcher from Cyornis to the newly described genus Leucoptilon (Sangster et al. 2021). Note change in gender ending to neuter.

Genome-wide SNPs confirm plumage polymorphism and hybridisation within a Cyornis flycatcher species complex. Zoologica Scripta, 00, 1– 16. https://doi.org/10.1111/zsc.12568

Morphology has been a leading taxonomic guiding light to systematists for the last couple of hundred years. However, the genetic and – more recently – genomic revolution have produced numerous demonstrations of erroneous classifications that were based on labile morphological traits. We used thousands of genome-wide markers to shed light on evolutionary dynamics in a confusing and taxonomically obscure group of Asian Cyornis flycatchers. Using genomic data, we corroborated recent findings based on three mitochrondrial and five nuclear genes that the two taxa hainanus and klossi which were previously treated as separate species (Cyornis hainanus and Cyornis rubeculoides klossi, respectively) are genomically homogeneous and form a single species, C. hainanus. We also uncovered a novel case of interbreeding between C. hainanus and a non-sister species, C. glaucicomans, illustrating these flycatchers' ability to hybridise in marginal situations even after substantial times of divergence. Our study illustrates how genome-wide loci can shed light on complicated taxonomic problems, resulting in a better integration of phenotypic and genotypic data.

IOC already have klossi in hainanus. No doubt someone will be able to update us on whether other authorities have made the switch before now.
