English Names

None noted.


Known with certainty from the upper Amazon Basin of southwestern Brazilian and Peruvian Amazonia, and two locations in the eastern slopes of the Andes in south central Peru; unnamed associated cryptic species (6 lineages) known from montane forests of western Venezuela to upper Rio Negro and lower Juruá drainages, Amazonas, Brazil, extreme northwestern Bolivia, and Amazonia of Peru, Ecuador, and Colombia. See comment. 

Geographic Occurrence

Natural Resident: Brazil, Peru

Likely/Controversially Present: Bolivia, Colombia, Ecuador, Venezuela


In the Leptodactylus marmoratus group according to the original publication, where external morphology, morphometrics, and the advertisement call were detailed. Carvalho, Moraes, Angulo, Werneck, Icochea, and Lima, 2020, Eur. J. Taxon., 682: 1–16, detected 8 lineages within this nominal taxon that differ in calls and mtDNA molecular markers of which the lineage containing the type locality is restricted to south-central Amazonian Peru and adjacent Amazonian Brazil. Martins, Mônico, Mendonça, Dantas, Souza, Hanken, Lima, and Ferrão, 2024, Zoosyst. Evol., 100: 233–253, suggested on the basis of comparative genetic distance that this nominal species is likely a species complex composed of 9 species, of which one was named as Adenomera albarena (from Amazonas, Brazil), one with the name Adenomera simonstuarti applied to it (from Amazonian Peru and Rondônia, Brazil), and the remaining 7 distributed from western Venezuela, eastern Colombia, eastern Ecuador, and Amazonian Peru and Rondônia, Brazil, and northwestern Bolivia).
