External morphology and the advertisement call were detailed in the original publication. Hoogmoed and Lescure, 1984, Zool. Meded., Leiden, 58: 88-92, resurrected Phyzelaphryne and provided a map of its distribution. Resurrected from the synonymy of Eleutherodactylus nigrovittatus by Hoogmoed and Lescure, 1984, Zool. Meded., Leiden, 58: 85, with which it had been synonymized by Lynch, 1980, Am. Mus. Novit., 2696: 1-24, and Lynch and Lescure, 1980, Bull. Mus. Natl. Hist. Nat. Paris, Sect. A, Zool., 2: 311. De la Riva, Köhler, Lötters, and Reichle, 2000, Rev. Esp. Herpetol., 14: 57, and Köhler, 2000, Bonn. Zool. Monogr., 48: 69, consider this species possibly to occur in Bolivia.
