Hylodes riveti Despax, 1911, Bull. Mus. Natl. Hist. Nat. Paris, 17: 92. Holotype: MNHNP 1902.357, according to Guibé, 1950 "1948", Cat. Types Amph. Mus. Natl. Hist. Nat.: 29.

Comment

In the Eleutherodactylus (Eleutherodactylus) martinicensis series, Eleutherodactylus unistrigatus group according to Lynch and Duellman, 1997, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 23: 231. Synonymized with Eleutherodactylus curtipes by Lynch, 1969, Herpetologica, 25: 266, but resurrected by Lynch, 1979, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 66: 37, who provided an account (unfortunately based on what has been subsequently named as Pristimantis lutzae according to Páez and Ron, 2019, ZooKeys, 868: 100), considered it most closely related to Eleutherodactylus balionotus, and noted previous misidentifications in the literature. Almendáriz C. and Orcés, 2004, Rev. Politécnica, Quito, 25: 128, provided distributional data for Ecuador. In the Pristimantis (Pristimantis) unistrigatus species group of Hedges, Duellman, and Heinicke, 2008, Zootaxa, 1737: 128. Not assignable to a species group according to Padial, Grant, and Frost, 2014, Zootaxa, 3825: 128. See statement of geographic range, habitat, and conservation status (as Eleutherodactylus riveti) in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 621. : 100–1xx, discussed the taxonomic status of the populations formerly assigned to this species (now including Pristimantis lutzae, Pristimantis gloria, Pristimantis multicolor, Pristimantis chomskyi, and an unnamed species). Coloma and Duellman, 2025, Amph. Ecuador. Vol. 3: 349–350, provided an account with photographs which summarized morphological identification, systematics, natural history, distribution (including a dot map for Ecuador), and conservation.
