Males of this moderately small species of Hyloxalus attain a snout-vent length of 21.0 mm, females, 22.7 mm. The discs on the fingers and toes are greatly expanded. Fingers I and II are equal in length, and Finger III is not swollen in males. Lateral fringes are absent on the fingers and toes; an outer tarsal fold present, and a curved inner tarsal fold is present on the distal half of the tarsus. Webbing is absent between the toes. The dorsum is brown with dark brown markings. The dorsolateral stripes are tan with an orange tint on head; the flanks are black with broken creamy white oblique lateral stripes. Ventrolateral stripes are absent. The thighs and upper arms are pale dull yellow with brown markings and the dorsal surfaces of the digital scutes are white, contrasting with adjacent brown surfaces. The venter is dull yellow; iris is pale copper. A median lingual process is absent, and the testes are white (Duellman 2004).
