Description and Conservation status of a new subspecies of Xenodacnis parina (Aves: Thraupidae) from the Ecuadorian Andes.
Xenodacnis is a Thraupid genus distributed in tropical high Andes. Its single member, X. parina, occurs in disjunct Andean ranges along paramo in southern Ecuador to puna from southern Peru. The population in Ecuador is separated by ca. 450 km from the nearest populations in Peru and its taxonomic a...

| Sumario: |
Xenodacnis is a Thraupid genus distributed in tropical high Andes. Its single member, X. parina, occurs in disjunct Andean ranges along paramo in southern Ecuador to puna from southern Peru. The population in Ecuador is separated by ca. 450 km from the nearest populations in Peru and its taxonomic affinities have not been evaluated since its discovery in 1980s at Cajas National Park. There are no major morphometric and plumage coloration differences reported in the genus Xenodacnis, I use criteria from integrative taxonomy to show that the isolated population from Ecuador withholds environmental and male song differences, compared to Peruvian subspecies, suggesting a different taxonomic treat, that was confirmed with morphometric differences, reporting bigger sizes; all these criterion place Xenodacnis parina from Ecuador as the most distinct member of the species. I propose this new subspecies of Xenodacnis parina and use new information to evaluate its conservation status according to the IUCN Red List criteria |
