Oreotrochilus cyanolaemus sp. nov.

Francisco Sornoza-Molina, Juan F. Freile, Jonas Nilsson, Niels Krabbe, and Elisa Bonaccorso (2018) A striking, critically endangered, new species of hillstar (Trochilidae: Oreotrochilus) from the southwestern Andes of Ecuador. The Auk: October 2018, Vol. 135, No. 4, pp. 1146-1171.

Abstract:

We describe a new species of the genus Oreotrochilus from the southwestern Andes of Ecuador. The new species is most similar in adult male plumage to O. stolzmanni and O. chimborazo. However, male and female show unique combinations of plumage characters that are likely to act as social signals. Phylogenetic analyses based on mitochondrial DNA indicate that this new taxon is closely related to O. stolzmanni and O. melanogaster, whereas genetic distances and preliminary comparisons of vocalizations suggest a sister relationship with O. stolzmanni. The geographic distribution of the new species seems to be restricted to cordillera Chilla-Tioloma-Fierro Urcu, in the southwestern highlands of Ecuador, an area historically poorly explored by ornithologists. Thus, based on its restricted distribution, apparently low population size, and lack of protection of its habitat, we evaluate it as critically endangered.

I was taken aback for a moment... I thought that Thorntails were in Furnariidae, not Trochilidae. But that's Spinetails... and Thornbirds. So okay, carry on SACC.

Ah yes...and then there's the following names, shared across different orders:

Spinetail: Apodidae (e.g. Zoonavena, Mearnsia), Furnariidae (e.g. Cranioleuca, Synallaxis)

Sicklebill: Trochilidae (Eutoxeres), Paradisaeidae (Drepanornis, Epimachus)

Thornbill: Trochilidae (Ramphomicron, Chalcostigma), Acanthizidae (Acanthiza)

Racket-tail (or Racquet-tail): Trochilidae (Ocreatus), Psittacidae (Prioniturus)

Note that at least one family in each pair is apodiform. Additionally, "Vulture" can now be considered to be shared between two orders, with the separation of Cathartiformes from Accipitriformes.

As well as grosbeaks, finches, buntings, tanagers, sparrows, flycatchers, warblers, and on and on. English names have described characteristics rather than phylogeny for ages, because after all the phylogeny is why we have the Latin names and taxonomy! The recent push to have English names "match" taxonomy just for the sake of matching seems fairly Quixotic. And in some cases downright silly, as in this case when it creates a nonsensical/oxymoronic name.

At least they're not as bad as genera that birds share with plants! eg Oenanthe and Prunella

Abstract

A new species of Campylopterus sabrewing is described from eastern Brazilian tropical dry forests occurring below 900 m asl. Its holotype (MZUSP 99024) is an adult female from Sítio Duboca (16°43’19’’S, 43°58’20’’W, elevation 840 m), municipality of Montes Claros, state of Minas Gerais. A taxonomic revision based on more than 1,000 museum specimens revealed that the new taxon, together with C. largipennis, C. diamantinensis and C. obscurus (with C. aequatorialis considered as a subjective junior synonym) should be ranked as species. We provide a key to permit easy identification of the four species. The new species is very similar to the parapatric C. diamantinensis of high altitude “campos rupestres” above 1,000 m asl, differing from it by its smaller size and longer light tail tips, as well as by sternum measurements. Given the several threats faced by the habitat to which the new species is endemic, we propose to consider it as Vulnerable under the IUCN criteria.

Keywords

cryptic biodiversity, Neotropical, Trochilidae, tropical dry forests, Aves

I like Limestone Sabrewing because limestone is in its Latin name and its the limestone why the forest are dry?
Etymology. The name calcirupicola is Latin, composed by “calx”, calcis, limestone; “rupes”, steep rocks; and “cola”, dwelling

Campylopterus calcirupicola

TiF Update August 5:

The Dry Forest Sabrewing, Campylopterus calcirupicola, is recognized as a separate species related to the Gray-breasted Sabrewing, Campylopterus largipennis. See SACC #756 and Lopes et al. (2017). Lopes et al. and SACC #755 suggest there are additional species in this complex.
