Head is not broader than body and wider than long. Snout is short, subacuminate when viewed dorsally and rounded in lateral view. The canthus rostralis is angular, straight or weakly concave. Loreal region is concave and slopes abruptly to the unflared lips. The interorbital region is broad; skin attaches to bone well and reveals the underlying osteology: low cranial crests medial to eyes, bony tubercles between crests. The tympanic annulus is never visible externally. Postrictal tubercles are round and small. Vomerine odontophores are posteromedially placed relative to the choanae, oblique, and each is approximately three times the size of the choana. Odontophores separated medially by a distance uqual to half width of odontophore (each with 4 or 5 teeth in an oblique row).

The dorsal skin ranges from smooth to “feebly warty.” Dorsolateral folds are distinct and fragmented posteriorly to sacrum. The region between the dorsolateral folds has many small warts whereas the flanks have large warts. Thenar tubercle is oval and approximately half the size of the bifid palmar tubercle. Fingers have fleshy lateral keels. Tip of thumb is not expanded into a disc whereas fingers II-IV have round discs.

Coloration in life is variable, usually the dorsal skin is red to brown with darker brown to black markings. The flanks are paler than the dorsal coloration. The ventral coloration is that of a dirty-cream to salmon. Labial stripes are creamy bronze. The iris is a pale copper with reddish-brown median horizontal streak.

Pristimantis gentryi is a member of the P. curtipes group. Pristimantis gentryi most closely resembles E. curtipes in having distinct but small digital discs, bony tubercles on the frontoparietals between the cranial crests, longer hind limbs and in lacking a tympanic annulus. In P. curtipes, the tympanic annulus is fully formed but is covered and concealed by the skin.
