Phrynopus tribulosus

[3] It inhabits humid montane forests where individuals could be found deep within a mossy bank by day.

[1] One specimen, now a paratype, is an adult female measuring 21 mm (0.83 in) in snout–vent length.

The dorsum is finely granular and has elongate dorsolateral warts that form a long discontinuous row without joining to a fold.

There is a bold black mask running from the snout through the eye and over to the sypratympanic area.

The lower parts are gray and have small, marmorated, brown, and metallic blue blotches.
