Phrynopus fallaciosus is a moderately large member of the genus; the single female by which this species is known measures 29.8 mm SVL. P. fallaciosus can be differentiated from its congeners by the following combination of characters: The skin on the dorsum and venter is smooth; first finger is slightly longer than the second; toes lack basal webbing and lateral fringes; there are two metatarsal tubercles with the inner being thee times larger than the outer; tympanic membrane and annulus distinct; snout rounded in dorsal and lateral view. Males from this species are unknown. The head is slightly narrower than the body, with the head being longer than it is wide (head width is 37.9% SVL, head length is 40.6% SVL). Supratympanic fold moderately heavy, obscuring upper and posterodorsal edges of tympanum. Length of tympanum is 53.1% length of eye. Heels of adpressed limbs overlap by one-fifth length of shank (shank is 57% SVL). In preservative coloration is as follows: dorsum is dull brown with darker brown markings made up of a canthal stripe from the nostril to the orbit, postorbital stripe encompassing tympanum, two labial bars on each side of head, median preorbital blotch, diffuse interorbital bar, W-shaped mark in scapular region, and diffuse transverse bars on limbs. Flanks grayish brown with few, small, dark brown spots. The iris is bronze with a median, horizontal red streak.
