Centrolene mariaelenae Cisneros-Heredia and McDiarmid, 2006, Zootaxa, 1244: 4. Holotype: DFCH-USFQ C125, by original designation. Type locality: "along a stream, tributary of the Jambue River, ca. 16 km S from Zamora, Podocarpus National Park (ca. 04° 15′ S, 78° 56′ W, 1820 m), on the western slope of Contrafuerte de Tzunantza, Cordilla Oriental, eastern slopes of the Andes, Provincia de Zamora-Chinchipe, Republic of Ecuador".
Chimerella mariaelenae — Guayasamin, Castroviejo-Fisher, Trueb, Ayarzagüena, Rada, and Vilà, 2009, Zootaxa, 2100: 31.
Amazonian Andean slopes, 1400-1820 m elevation, in the provinces of Napo, Tungurahua, Morona-Santiago, and Zamora-Chinchipe, Ecuador, on to the Kampankis Mountains between the Santiago and Morona rivers of northwestern Peru, and possibly into adjacent southern Colombia.
In the Centrolene gorzulae group according to the original publication. Cisneros-Heredia and Guayasamin, 2007, Check List, 2(3): 93-95, a range extension and discussed the range. Cisneros-Heredia and Meza-Ramos, 2007, Zootaxa, 1485: 38, noted that the lack of apomorphies associating this species with Hyalinobatrachium did not imply that Cochranella is monophyletic and that further phylogenetic work should elucidate relationships and provide for a corresponding monophyletic taxonomy. Kok and Castroviejo-Fisher, 2008, Zootaxa, 1680: 27, transferred this species to the Centrolene gorzulae species group. Guayasamin, Castroviejo-Fisher, Trueb, Ayarzagüena, Rada, and Vilà, 2009, Zootaxa, 2100: 31, transferred the species to Chimerella. Cisneros-Heredia, 2009, Check List, 5: 912-916, reported on an additional specimen and suggested that this species may be found in southern Colombia. Terán-Valdez and Guayasamin, 2014, CienciAmérica, Quito, 3: 17–22, reported on larval morphology. Catenazzi and Venegas, 2012, in Pitman et al. (eds.), Rapid Biol. Social Invent. Rep. 24: 260, reported the species in Peru.
