Atelopus pulcher (Boulenger, 1882)
Accepted species in Catalogue of Life’s 11 September 2026 base release. This preserves the source classification and available supporting data; it is not a completed species monograph.
These harlequin frogs, listed critically endangered by IUCN, were fairly abundant on a path in the A.C.R. Cordillera Escalera during the day. Since they only live around the upper río Huallaga valley, where many suitable habitats have been destroyed, these beautiful frogs are fighting extinction.
