Dorsal skin is shagreen and coarser on flanks. It is finely granular on the upper surfaces of the limbs. Skin on belly is areolate and that on throat is smooth. Palmar tubercle is bifid and slightly larger than the oval thenar. Subarticular tubercles are round. There is a fringe present along the outer edge of palm and finger IV, disc on thumb is narrow while finger II is as wide as the tympanic annulus. Discs on fingers III and IV are larger than tympanic annulus.
In life, the coloration of the dorsum is a pale creamy tan to dusky yellow. If pale spots are present their coloration is that of a pale yellow to a pale orange. Throat and venter are white. Iris is pale greenish-gray to coppery orange with brown flecks or fine black reticulation.Pristimantis eugeniae is most similar to P. nyctophylax which is of equal size on the Pacific versant of the Ecuadorian Andes. However, Pristimantis nyctophylax, unlike P. eugeniae, has small tubercles on the upper eyelid and heel, a more angular canthus rostralis, areolate plantar surface and the posterior surfaces of the thighs are brown with cream flecks.
