In this small species of Allobates males attain a snout-vent length of 16.9 mm and females reach 18.4 mm. The discs on the fingers and toes are expanded, half again the width of the penultimate phalanges. Finger I longer is than Finger II, and Finger III is swollen in males. Lateral fringes are absent on the fingers and toes. Inner and outer tarsal folds are absent, but an outer tarsal tubercle is present. Basal webbing is present between Toes II and IV; elsewhere webbing is absent. The dorsum is tan with brown markings usually consisting of an interorbital bar and an X-shaped mark in the scapular region; the posterior parts of the X-shaped mark may be connected to a roughly triangular mark in sacral region. The dorsolateral stripes are pale yellow, narrow on the head and diffuse on the body. A broad, dark brown stripe across tip of snout passes through the loreal and tympanic regions, becomes broader on the flanks, and extends to the groin; it is bordered below on the flanks by a narrow pale yellow ventrolateral stripe. The flanks below the ventrolateral stripes are creamy tan with brown flecks. Oblique lateral stripes are absent. The dorsal surfaces of the hind limbs are grayish brown with many small dark brown flecks and one broad transverse brown bar on each thigh, shank, and foot; the posterior surfaces of the thighs are brown. The labial region is creamy white with brown flecks; the throat and belly are pale lemon yellow, and the ventral surfaces of limbs are flesh colored. The digital scutes are pale gray, in contrast to the adjacent dark brown surfaces; the iris is greenish bronze. A median lingual process is absent; the color of the testes is unknown.
