See account by Coloma, 1995, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 87: 33. Kaplan, 1997, J. Herpetol., 31: 373. Almendáriz C. and Orcés, 2004, Rev. Politécnica, Quito, 25: 110, provided distributional data for Ecuador. See statement of geographic range, habitat, and conservation status (as Colostethus infraguttatus) in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 613. Sánchez, 2013, Zootaxa, 3637: 586, reported the species from Barbacoas municipality, Nariño, Colombia. Armijos-Ojeda, Székely, Székely, Cogǎlniceanu, Cisneros-Heredia, Ordóñez-Delgado, Escudero, and Espinosa, 2021, ZooKeys, 1063: 37, mapped the species as extending into extreme northwestern Peru but the associated supplemental data are confusing.
