The generic nomenclature of the Trochilini: a correction
F. GARY STILES, J. V. JR. REMSEN

Abstract

Because the generic name Elliotia proposed by us (Stiles et al. 2017a) was found to be preoccupied, we herein rename this genus, including a detailed diagnosis; the generic circumscription and type species remain unchanged. This change does not affect the generic reorganization of the Trochilini presented by Stiles et al. (2017a).

But remember what they wrote earlier:

Quote:
We also cannot find support for the statement by Schuchmann (1999) that these species had been “often alternatively placed in genus Chionogaster”, or indeed that the name Chionogaster has ever been used in a generic sense: it does not appear in Zoonomen (Peterson 2009) or in any of the synonymies of the original sources we have consulted. A new generic name for chionogaster and viridicauda is therefore necessary.
There is still the chance that there is a souce they haven't consulted.

In fact Schuchmann wrote nothing from often. Here is what we find in HBW:

Quote:
In the past, alternatively placed in genus Chionogaster, along with A. viridicauda; sympatric with latter species in Urubamba Valley (C Peru), where hybridization not yet demonstrated.
Maybe in Hummingbirds, Their Life and Behavior: A Photographic Study of the North American Species?

It's not really possible to be certain without having seen the entire book, but the mere use of a name in a list at apparent subgeneric rank (as in the snippet of Tyrell's book that can be seen on Google -- note that Schuchmann wrote about a genus Chionogaster, not a subgenus) makes that name available as a genus-group name only in works published before 1931. In a work published after 1930 (here: 1985), you need a statement (in words) of characters purported to differentiate the taxon -- short of this, the name is a nomen nudum.


Currently, I am a bit more concerned about Leucolia, which still needs a valid type designation. In SACC Prop. 781, Gary Stiles wrote:
Quote:
We note here that we had accepted viridicauda as its type following the recommendation of Elliot, but this was incorrect because it was described after Leucolia was named; we have submitted a manuscript (Stiles et all, submitted) substituting violiceps as the type species to correct this error.
I more or less expected that this would be done in the same paper as the (re-)description of the group they had named Elliotia... But this wasn't.
The nominal species originally included in Leucolia are listed in [my post 128 above]; as long as one of these has not been designated, they are all eligible to become the type species of the name. These species include chionogaster Tschudi, the type of Elliotomyia, thus Leucolia is currently a potential objective senior synonym of this name.
(IOW, it would be not be fully safe to adopt Elliotomyia for now, because it has a sword of Damocles above it -- the publication, by anyone, anywhere, of a simple statement that chionogaster is the type of Leucolia, would make it readily invalid.)

Laurent. You mentioned Leucolia: "This name has been little used outside of the French literature." I wonder if this publication makes a designation of a type? It mentions the generic name 34 times.

Thanks Mark, but I know this work, which is:
Eudes-Deslongchamps E. 1879-80. Catalogue descriptif des oiseaux du musée de Caen appartenant à la famille des Trochilidés ou oiseaux-mouches. Bull. Soc. Linn. Normandie, sér. 3, 3: 149-321; 4: 8-225.
https://biodiversitylibrary.org/page/9719452; https://biodiversitylibrary.org/page/9723397
The word 'type' is used therein exclusively in the sense of a specimen. Not a single time in the sense of a type species.

Eriocnemis

Paolo Ramoni‐Perazzi, Karl‐L. Schuchmann, André Weller, Irma Alejandra Soto‐Werschitz & Marcelo Passamani. Niches and radiations: A case study on the Andean Sapphire‐vented Puffleg (Eriocnemis luciani) and Coppery‐naped Puffleg (E. sapphiropygia) (Aves, Trochilidae). Journal of Avian Biology. First published: 12 November 2019 https://doi.org/10.1111/jav.02242

Abstract:

The interaction between ecology and evolution, particularly with regard to speciation processes, remains a main topic of scientific research. Andean hummingbirds have undergone remarkable radiation, with many species exhibiting patchy distributions and, in some cases, taxonomic controversy. An example is the Sapphire‐vented Puffleg (Eriocnemis luciani; ssp. baptistae, luciani, and meridae), which some authors merge with the Coppery‐naped Puffleg (E. sapphiropygia; ssp. catharina and sapphiropygia). Each group is distributed either north or south from the Huancabamba Depression, the major biogeographical barrier within the tropical Andes. We investigated whether these subspecies share some niche characteristics despite their geographical separation and determined their meaning in the context of the speciation process of trochilids in the tropical Andes. For each subspecies, we performed geographical predictions and paired tests of niche conservatism in environmental space. Geographical predictions included separate regions for subspecies catharina and sapphiropygia, while the predicted regions for subspecies luciani and baptistae greatly overlapped. The E. l. luciani model predicted a single pixel near to the potential area of E. l. meridae, known only from a unique, old record. Subspecies luciani and baptistae exhibited the greatest niche overlap among the pairs of taxa for most variables. However, our results clearly indicated niche divergence for the four members of the E. luciani‐sapphiropygia complex, independent of the similarities or slight dissimilarities in their respective backgrounds, indicating that other forces in addition to variation in environmental parameters, such as natural selection or genetic drift, are driving the radiation of these hummingbirds. This finding coincides with the unusually high speciation rates reported for Andean hummingbirds. Thus, the currently accepted taxonomy within the E. lucianisapphiropygia complex maybe even more convoluted than indicated by previous studies. Hence, the results of our study are a wakeup call to include the exploration of lineage diversification in biodiversity‐related efforts.
