The species had previously been confused with Ameerega parvula (as Epipedobates) according to the original publication. See comment under Ameerega ingeri. See account by Lötters, Jungfer, Henkel, and Schmidt, 2007, Poison Frogs: 323-325, who placed this in their Ameerega picta group. Poelman, Verkade, and van Wijngaarden, 2010, J. Herpetol., 44: 409-417, reported on larval morphology. Venegas and Gagliardi-Urrutia, 2013, in Pitman et al. (eds.), Rapid Biol. Social Invent. Rep. 25: 255, reported the species from Peru. In the Ameerega parvula species group of Guillory, French, Twomey, Chávez, Prates, von May, De la Riva, Lötters, Reichle, Serrano-Rojas, Whitworth, and Brown, 2020, Mol. Phylogenet. Evol., 142 (106638): 1–13.
