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.

Proposal (808) to SACC:

Species limits in Oreotrochilus

A. Elevate Oreotrochilus estella stolzmanni to species rank

B. Recognize newly described Oreotrochilus cyanolaemus

"Racket-tailed Thorntail" doesn't exactly roll off the tongue. But if there is a Dark-eyed White-eye, then sure, why not?

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
