Comment

Removed from the synonymy of Atelopus ignescens by McDiarmid, 1971, Sci. Bull. Nat. Hist. Mus. Los Angeles Co., 12: 39, where it had been placed by Nieden, 1926, Das Tierreich, 49: 83. Coloma, Lötters, and Salas, 2000, Herpetologica, 56: 310–319, provided a detailed account of the species. See photograph, map, description of geographic range and habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 165. Toral, Frenkell, and Salas, 2005, in Rueda-Almonacid et al. (eds.), Ranas Arlequines: 75, provided a brief account, photograph, and map. Astudillo, Jiménez, Siddons, and Timbe, 2022, Rev. Peruana Biol., 29 (e22742): 1–4, provided new localities and discussed habitat and conservation.
