Comment
See account by Coloma, 1995, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 87: 31. See comment regarding diagnosis by Rivero and Almendáriz C., 1992 "1991", Rev. Politécnica, Quito, 16: 117. See comment under Hyloxalus parcus. Coloma and Duellman, 2025, Amph. Ecuador. Vol. 2: 23–24, provided an account (as Allobates exasperatus), with photographs, which summarized identification, adult and larval morphology, systematics, natural history, distribution (including a dot map for Ecuador), and conservation. They also transferred this species to Allobates on the basis of overall similarity, neglecting the synapomorphic black arm gland shared with Hyloxalus nexipus. The species is retained here in Hyloxalus pending molecular data or further discussion.
