"Cochranella" euhystrix is a species of frog in the family Centrolenidae. It has an uncertain placement (incertae sedis ) within subfamily Centroleninae (hence the quotation marks around the genus). It is endemic to Peru and only known from the vicinity of its type locality near Cerro Blanco, in the Zaña River watershed, Department of Cajamarca. The specific name euhystrix (from Greek prefix eu, "very", and hystrix, "porcupine") refers to the unusually spiny appearance of this frog, especially males. Common name ridge Cochran frog has been proposed for this frog.

starts withAdult males measure 29–31 mm (1.1–1.2 in) and adult females 31–34 mm (1.2–1.3 in) in snout–vent length. The head is wider than the body. The snout is truncate, sometimes slightly rounded in profile in females. The tympanum is distinct, but partly covered by the heavy supratympanic fold, especially in females. The fingers have lateral fringes and are partially webbed; the toes are heavily webbed. All digits bear expanded discs. The dorsum is dark greenish black in active individuals and dark green in inactive ones. The color can change rapidly. There are many light green spicules, especially on the eyelids lips, that give the upper parts a finely dotted appearance. Females have fewer spines than males.
The male advertisement call is a short "click" or "chirp". Most calls consist of two notes in rapid succession but some calls have a single note only.
