Pristimantis euphronides is a moderate-sized frog for its genus. Males have been known to have a maximum snout to vent length (SVL) of 27mm while females at 39.4mm. Labial areas are typically mottled, while a brown dorsum and cream venter are also exhibited. There exists a supratympanic stripe of dark shade that runs from the corner of the eye to the armpit. The thighs of the species are characterized by an orange-brown to red color, while the upper iris is bronze.The 2n = 32 chromosome complement is of a ZW/ZZ sex determination and displays an unusually large heterochromatic W chromosome. The findings of Schmid et al. (2002) classified the species as possessing one of the smallest genomes coupled with one of the largest W chromosomes among all amphibians.

This species is most commonly found in mesic forests at elevations of over 300 meters on Granada (Kaiser and Henderson 1994) . More generally, the species may be located within altitudes of 300-840m, which has been listed as its elevational range (Hedges 1999) . An account has also been described near sea level at St. George’s (Schwartz 1967) .

Males of species Pristimantis euphronides and Eleutherodactylus johnstonei have been documented as calling side by side in the Grand Etang forest interior by (Germano et al. 2003) . The grayish eggs of P. euphronoides may be distinguished by their large diameter, relative to those of E. johnstonei.

While Kaiser et al. (1994b) reported a drop of this species population coupled with the encroachment of Eleutherodactylus johnstonei, Germano et al. (2003) documented the lack of a significant decline upon P. euphronides by the presence of E. johnstonei in the Grand Etang Forest Reserve.
