English Names

Urrao Cochran Frog (Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 47).

Greater Andean Glassfrog (Trageser, Maynard, Culebras, Kohn, Quezada, and Guayasamin, 2021, Phyllomedusa, 20: 30). 

Distribution

Western slope of the Cordillera Occidental in Antioquia, Risaralda, Valle de Cauca, and Chocó departments, Colombia (4° 50′ N–7° 20′ N), 1700–2100 m elevation; cloud forest in Río Manduriacu Reserve, Imbabura Province, and near Mindo, Pichincha Province, northwestern Ecuador, 1850 to 1857 m elevation. 

Comment

In the Cochranella ocellata group according to Ruiz-Carranza and Lynch, 1991, Lozania, 57: 1–30. Placed in the Cochranella spinosa group by Savage, 2002, Amph. Rept. Costa Rica: 365. See account by Rada and Guayasamin, 2008, Pap. Avulsos Zool., São Paulo, 48: 89–101. See statement of geographic range, habitat, and conservation status (as Cochranella megistra) in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 613. Guayasamin, Castroviejo-Fisher, Trueb, Ayarzagüena, Rada, and Vilà, 2009, Zootaxa, 2100: 57, considered this species to be incertae sedis within Centroleninae. Trageser, Maynard, Culebras, Kohn, Quezada, and Guayasamin, 2021, Phyllomedusa, 20: 27–35, provided molecular evidence to place this species unambiguously in Nymphargus, the sister taxon of Nymphargus grandisonae, and they provided the first records from Ecuador (Río Manduriacu Reserve, Imbabura Province, and near Mindo, Pichincha Province), both in Chocoan northwestern Ecuador, including discussion of morphology and natural history.
