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:

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:

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.

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:

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.

Click to expand...

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:
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.

Phylogenetic relationships and systematics of a subclade of Mesoamerican
emerald hummingbirds (Aves: Trochilidae: Trochilini)
BLANCA E. HERNÁNDEZ-BAÑOS, LUZ E. ZAMUDIO-BELTRÁN, BORJA MILÁ

Abstract

Phylogenetic relationships among major hummingbird clades are relatively well resolved, yet due to the lack of morphological synapomorphies and relative phenotypic homogeneity, the systematics of several hummingbird groups remain unresolved. Here, we present the results of a multilocus study of a clade of emerald hummingbirds composed of Cynanthus, Chlorostilbon, Riccordia and Phaeoptila (sensu Stiles et al. 2017). We include taxa not analyzed in previous studies (C. lawrencei, C. auriceps and C. forficatus, from Tres Marías Islands, Western Mexico, and Cozumel Island, respectively), and this allows us to develop a new hypothesis for the phylogenetic relationships within this group. We found that this clade originated in Mesoamerica about 12 million years ago, and comprises four geographically congruent clades: (a) the most basal clade, Phaeoptila sordida, of the Balsas River basin, Mexico; (b) Riccordia bicolor, R. maugaeus, R. ricordii and R. swainsonii of the West Indies; (c) Chlorostilbon assimilis, C. aureoventris, C. melanorhynchus, C. mellisugus, C. poortmani and C. pucherani, all of South America, except C. assimilis of Central America; and (d) a Mesoamerican clade with two Cynanthus subclades: a widespread Mexican clade that includes species formerly belonging to the genus Chlorostilbon: Cynanthus auriceps, C. canivetii, C. doubledayi and C. forficatus; and a clade restricted to the west coast of Mexico and the Tres Marías Islands and composed of C. latirostris and C. lawrencei. Our results help clarify the systematics of this group of emeralds, reconstruct its true evolutionary history, and advance understanding of phenotypic evolution in hummingbirds.

Sometimes I feel like repeating code questions but I am once again not 100% sure about the code rule in case of:

Scale-throated Hermit (Phaethornis eurynome paraguayensis) Bertoni, M & Bertoni, AW, 1901 here at IOC World bird list and OD here. Of course I see both names next to the name. But the publication is only by Arnaldo de Winkelried Bertoni here. I feel 50.1.1. of the code is not applicable in this case. Correct?

Taphrospilus said:

Correct?

I'd say yes.
This was the interpretation of the first authors who dealt with Bertoni's work, btw:

• Arribálzaga 1902 https://www.biodiversitylibrary.org/page/14592777 : Phaethornis paraguayensis Bert. sp. nova.
• Ihering 1904 https://www.biodiversitylibrary.org/page/11191846 : Ph. paraguayensis Bertoni.
• Richmond index http://www.zoonomen.net//cit/RI/SP/Peta/peta00356a.jpg : Phaethornis paraguayensis "M. et W. Bertoni" A. de W. Bertoni 1901.

Thank's but Richmond had "Moisés Santiago Bertoni" in quotation marks. So I assume he did not consider him either. But HBW/Cornell Labs of Ornithology mentions as well both authors. Any other reason why to consider both as author?
