Comment

See Schulte, 1990, Bol. Lima, 12: 57-68, for second locality and discussion of relationships. Schulte, 1999, Pfeilgiftfrösche: 148-157, provided an account. Grant, Frost, Caldwell, Gagliardo, Haddad, Kok, Means, Noonan, Schargel, and Wheeler, 2006, Bull. Am. Mus. Nat. Hist., 299: 174, discussed the species, known only from the holotype, and could not allocate it beyond Dendrobatinae, merely retaining it in a non-taxon "Dendrobates". Lötters, Jungfer, Henkel, and Schmidt, 2007, Poison Frogs: 625-626, provided an account. Twomey and Brown, 2008, Herpetologica, 64: 121–137, described the advertisement call. See photograph, map, description of geographic range and habitat, and conservation status (as Dendrobates mysteriosus) in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph.
