Taxonomic status of Paraguay’s only endemic bird, the Chaco Nothura Nothura chacoensis (Aves: Tinamidae)

FLOYD E. HAYES, OSCAR RODRÍGUEZ, ERIKA R. THALMAN, EMILY A. CASTELLANOS, JOHN STERLING

Abstract

The Chaco Nothura Nothura chacoensis Conover is endemic to the Chaco of western Paraguay. Originally described as a subspecies of the Spotted Nothura N. maculosa (Temminck), it has been regarded by many authorities as a distinct species based on alleged sympatry with N. maculosa. However, an earlier study revealed no differences in cytochrome b sequences between the two taxa. We reanalyzed the geographic distribution and morphological variation of N. chacoensis and N. maculosa in western Paraguay based on museum specimens. There is no locality where specimens of both taxa were collected, thus there is no evidence for sympatry. Morphologically the two taxa did not differ in any size or shape variable. Plumage characters overlapped in a few specimens. We recorded vocalizations from at least four individuals of N. chacoensis within its known range. Its typical territorial song was a very rapid, relatively monotone trill that was virtually identical with the most frequent territorial song of N. maculosa in length, number of notes, rate of notes, and emphasized frequency, and differed substantially from the songs of other species of Nothura. Based on distributional, morphological, biochemical, and especially vocalization data, we conclude that N. chacoensis should be regarded as a subspecies of N. maculosa.

It must be tough to undo splits in this day and age that were obviously non-starters to begin with. This paper might just scrape the grade, while everyone in the region knew it was coming.

What gets my back up is tour companies selling people a lie, when they know Chaco Nothura is a duffer.
 
TiF Update Marsh 15

Tinamous: Hayes et al. (2018) showed that there is no reason to consider the Chaco Nothura, Nothura chacoensis, distinct from the Spotted Nothura, Nothura maculosa. As a result, I now consider the Chaco Nothura to be a subspecies of the Spotted Nothura, Nothura maculosa.
[Tinamidae, Paleognathae, 3.03]
 
Nothura is a member of subfamily Nothurinae Miranda-Ribeiro, 1938, according to some authors. I also recognise two subfamilies, but I use Rhynchotinae von Boettischer, 1934, instead of Nothurinae, by priority. But, there is a third synonym named Tinamotidinae Salvadori, 1895, which, in theory, should be used as subfamily.

Do you have more information about Tinamotidinae and which of these three names should I really use ? (in principle, Tinamotidinae, but.....)

Not sure if these two parts of the ICZN apply?
35.5. Precedence for names in use at higher rank. If after 1999 a name in use for a family-group taxon (e.g. for a subfamily) is found to be older than a name in prevailing usage for a taxon at higher rank in the same family-group taxon (e.g. for the family within which the older name is the name of a subfamily) the older name is not to displace the younger name.

Example. The subfamily ROPHITINAE Schenck, 1866 (Hymenoptera) is universally included in the family HALICTIDAE Thomson, 1869, even though on priority alone the name of the family would be ROPHITIDAE. The precedence of HALICTIDAE over ROPHITIDAE is to be maintained as long as they are treated as subjective synonyms (at family rank), and HALICTINAE and ROPHITINAE are used for different subfamilies within the HALICTIDAE.
Article 40. Synonymy of the type genus.

40.1. Validity of family-group names not affected. When the name of a type genus of a nominal family-group taxon is considered to be a junior synonym of the name of another nominal genus, the family-group name is not to be replaced on that account alone.

Example. The name NEOSITTINAE Ridgeway, 1904 (Aves) is valid rather than DAPHOENOSITTINAE Rand, 1936, even though the name of the type genus Neositta Hellmayr, 1901 is a junior synonym of Daphoenositta De Vis, 1897.

40.2. Names replaced before 1961. If, however, a family-group name was replaced before 1961 because of the synonymy of the type genus, the substitute name is to be maintained if it is in prevailing usage.
