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).

Elliotomyia, gen. nov.
Type species: Trochilus chionogaster Tschudi, 1846.
Included species:
Elliotomyia chionogaster (Tschudi, 1846) - Ariane à ventre blanc; White-bellied Hummingbird
Elliotomyia viridicauda (von Berlepsch, 1883) - Ariane du Pérou; Green-and-white Hummingbird
Gender feminine
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.
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.
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.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.
Thanks Mark, but I know this work, which is: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.

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.
I'd say yes.Correct?
I'd say yes.
