Synallaxis gujanensis subsp. pulvericolor

Abstract

<i>Synallaxis gujanensis pulvericolor</i> (Sclater, 1858) (new combination) <p> <i>Anabates pulvericolor</i> Sclater, 1858: 62. Holotype, by original monotypy: lost, from “Río Napo, Ecuador ”; according to Paynter (1993) the latitude and longitude are 03°20’S, 76°40’W, respectively. Neotype, by present designation: ANSP 185383 (tissue sample ANSP 19367), adult male, from Río Napo, island at mouth of Río Aguarico, Ecuador, 150 m elevation, netted on September 20, 1992 and prepared by Francisco Sornoza.</p> <p> <i>Synallaxis gujanensis huallagae</i> Cory, 1919: 274. Holotype, by original designation: FMNH 50561, adult male, from “Lagunas, Lower Huallaga River, Peru ”; according to Stephens & Traylor (1983) the latitude and longitude are 05°10’S, 75°32’W, respectively; collected by M. P. Anderson on October 12, 1912.</p> <p> <b>Neotype descriptive notes</b>. Plumage analysis given using the code developed by Smithe (1974, 1981) to define colours and following the topography of Proctor & Lynch (1993: 49, 51): chin and throat white; breast Light Drab (119C); abdomen white with Drab-Gray (119D); flanks Raw Umber (123); forehead, crown and supercilium Grayish Horn Color (91); back Olive-Brown (28) with Amber (36); five pairs of rectrices, wing-coverts and remiges Raw Sienna (136). Morphometric data: bill length, 15.1 mm (exposed culmen from the feathers to tip); bill height, 4.4 mm (at the nares); wing length, 64.1 mm (chord); and tail length, 70.1 mm (using the central pair of rectrices) (see <b>Figure 2</b>).</p> <p> Finally, note that this is a nomenclatural and not a taxonomic work, and therefore the potential validity of <i>Synallaxis gujanensis huallagae</i> Cory, 1919 as the nomen for a separate population (to be extracted from that including Río Napo) is not considered. We are only maintaining here the classification given in the recent world checklists (e.g. Dickinson & Christidis 2014 and del Hoyo <i>et al</i>. 2016).</p>Published as part of <i>Stopiglia, Renata, Dubois, Alain, Bockmann, Flávio A. & Raposo, Marcos A., 2019, The taxonomic and nomenclatural status of the nomen Anabates pulvericolor Sclater, 1858 (Aves: Furnariidae), with a neotype designation, pp. 554-562 in Zootaxa 4560 (3)</i> on page 558, DOI: 10.11646/zootaxa.4560.3.7, <a href="http://zenodo.org/record/3993490">http://zenodo.org/record/3993490</a&gt
