The scientific name of this species means "long-snout" and the species has been named in Spanish as the jambato hocicudo. Common names longnose stubfoot toad, scrawny stubfoot-toad, and longnose sharlequin frog have been coined for it.

Accordingly, common name blue-spotted toad has been coined for it.
The Northwestern Andean montane forests (NT0145) is an ecoregion on the Andes mountains in the west of Colombia and Ecuador. Both flora and fauna are highly diverse due to effect of ice ages when the warmer climate zones were separated and the cooler ones combined, and interglacial periods when the reverse occurred. Because the environment is hospitable to humans, the habitat has been drastically modified by farming and grazing since the Pre-Columbian era.
