Comment

See account by Coloma, 1995, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 87: 16. Almendáriz C. and Orcés, 2004, Rev. Politécnica, Quito, 25: 109, provided distributional data for Ecuador. Venegas and García Ayachi, 2024, Rev. Latinoam. Herpetol., 7(4: e1048): 247–251, reported the species from Huamba District, Ayabaca Province, Piura Department, Peru, and provided a dot map of the species' range. Coloma and Duellman, 2025, Amph. Ecuador. Vol. 2: 109–112, provided an account, with photographs, which summarized identification, adult and larval morphology, systematics, natural history, distribution (including a dot map for Ecuador), and conservation. They also noted that the tadpoles described under this name by Coloma, 1995, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 87: 1–72, are (tentatively) referrable to Telmatobius niger
