Holotype in the original description by Arntzen and Garcia-Paris (1995) is probably a male with a snout-vent length of 35.1mm. The eyes are large and have a vertical slit-shaped pupil. Parotid glands are short and slim, but well marked. Red-orange glandular spots, as present in other Alytes species, are absent. Marked line of white glandular tubercles running along side of trunk. There are three metacarpal tubercles. Background coloration of back gray, with many gray and blackish fine dots equally mixed with pale ones. This gives the frog a "dusty" appearance. A marked gray zone is present between the eyes.
