Cochranella erminea is found in a variety of habitats, including primary premontane forests, disturbed foothills, and near streams and waterfalls. It may be found in the canopy during non-reproductive periods.
The female holotype measured 23.6 millimetres (0.93in) in snout-vent length. The back is green, with flat warts. The warts have white and dark blue spots. The dorsal skin is shagreened.
The tympanum is ovoid. The vomer has teeth. The snout is sloping anteroventrally, and rounded dorsally. The nostrils are slightly elevated. The upper lip is white. The iris is pale or slate grey, with darker grey lines.

Conservation
In 2017, the IUCN assessed Cochranella erminea as of Least Concern. The species faces no major threats, though pesticide runoff may be a localised threat. It is present in the Machiguenga Communal Reserve.
Etymology
The specific epitheterminea is derived from the Latin ermineus, meaning "white like ermine". It refers to the white warts on the frog's back.
