Diagnosis: A small red-eyed treefrog, brown to light-green in color, with a white stripe running from snout to groin and expanded into a large white suborbital spot, a moderately-sized tympanum, yellow posterior thigh, and yellow venter (Savage 2002).
Description: Adult males are 30-33 mm SVL, and adult females are 30-36 mm in SVL. Head is wider than long, with a snout that is rounded in profile and truncate in dorsal view. Eyes are large. The tympanum is distinct and moderate-sized, measuring 55-63% of the eye diameter. Fingers are short and stout with minimal webbing between fingers, and only vestigial webbing between fingers I and II. Fingers each have a single distal subarticular tubercle. Toes are moderately webbed. A large oblong metatarsal tubercle is present but no inner metatarsal tubercle. The dorsum is smooth and the venter is granular. In adult males, a single moderately distensible internal subgular vocal sac and vocal slits are present, as well as a nonspinous brown nuptial pad on the base of the thumb (Savage 2002; Savage 1968).
Coloration is light brown or light to bright green. This species is able to change color, exhibiting metachrosis. Eyelids and the top of the head have green and brown flecking when the frog is in the brown phase. A light stripe begins at the snout, continues along the head, expands into a large subocular spot, and continues along the flank to the groin. Light stripes run along the margins of the forearms, feet, and above the cloaca. Limbs have no transverse bars. The upper forearm is yellow with an oblique white stripe. Anterior and posterior surfaces of the thighs are yellow. All ventral surfaces are yellow. The vocal sac is white. Iris is bright red (Savage 2002; Savage 1968).
This species may be synonymous with D. rufioculis, according to Solís et al. (2004); it was originally thought to be synonymous by Duellman (1970) but was separated by Myers and Duellman (1982) after the latter authors collected additional specimens from northwestern Panama that differed in the size of the tympanum and ventral coloration (Savage 2002).
