Blue Mountain Rockfrog

Males grow to 28 mm (1.1 in) and females to 32 mm (1.3 in) in snout–vent length. The head is as wide as it is long. The snout is acuminate but sharply truncate. The tympanum is small but visible. The digital discs are moderately sized. No webbing is present. Dorsal coloration is tan to gray, with some individuals having hint of red or orange. Dorsal patterns are variable; most individuals are either mottled with dark brown or have tan or reddish tan dorsolateral stripes. Scapular W-shaped marking is almost always present, often followed by another W in mid-dorsum. Many individuals have lateral spotting. Ventral coloration is pale yellow, often with brown or back pigmenting. The throat is heavily pigmented.

This species is restricted to eastern Jamaica. It is found from sea level to 1,650 m (5,410 ft) asl. It is also reported from one location on the north coast, but it is unknown whether this represents a viable population. It is a terrestrial frog that is often found on and inside rocky formations in rainforest but also in secondary forest. It can also occurs inside piles of coconut husks. Eggs are laid on the ground and it breeds by direct development (i.e., there is no free-living larval stage).
