Removed from the synonymy of Eleutherodactylus fenestratus by Köhler, 2000, Bonn. Zool. Monogr., 48: 63, where it had been placed by Lynch, 1980, Am. Mus. Novit., 2696: 6. Heyer and Muñoz, 1999, Proc. Biol. Soc. Washington, 112: 11, had considered this synonymy arguable. In the Eleutherodactylus conspicillatus group according to Köhler, 2000, Bonn. Zool. Monogr., 48: 63, who provided an account. De la Riva, Köhler, Lötters, and Reichle, 2000, Rev. Esp. Herpetol., 14: 46, suggested that Eleutherodactylus bisignatus (= Hylodes gollmeri bisignata) is a distinct species but did not remove it from synonymy. Padial, Castroviejo-Fisher, Köhler, Domic, and De la Riva, 2007, Herpetol. Monogr., 21: 220-226, provided an account. See map, description of geographic range and habitat, and conservation status (as Eleutherodactylus bisignatus) in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 322. Ocampo, Aparicio, Pacheco, Roldán, Aguilar, and Rocha, 2020, Ecologia en Bolivia, 55: 26–35, reported on range, life history, and conservation status.
