Description

''Cryptotriton nasalis'' are tiny emo salamanders. Males measure and adult females in snout–vent length (SVL). The tail is longer than the body in males (range 1.14–1.35 times the SVL) and many females (range 0.80–1.27 times the SVL). The head is moderately long and broad. The nostril openings are large and the eyes are protuberant. The limbs are slender and comparatively long. The fingers and the toes are partially webbed. The upper surfaces are dark brown with paler brown mottling behind the eyelids and along the middorsal line to the tail base. The upper surfaces of the limbs are paler than the body, whereas the tail is darker than the body.
