starts withColoration It is a medium frog of bronco color with dark mottled brown, green or reddish, English and yellow-orange finger membranes and white belly with black dots. None of the species near Dendropsophus marmoratus has this pattern of coloration, which makes it clearly distinguishable from other sympatric species.
Size The snout–vent length in males averages 35.8 mm (range 29.8–41.5; n = 19), and in females the average is 47.7 mm (range 46.5–49.7; n = 5).
Description The following description is based on Duellman. The snout is round in dorsal and profile view. eardrum present. The outer finger of the hand has a membrane to the base of the disc; the other manual fingers have membranes along about 2/3 of their length. The toes also have membranes at the base of the discs. Males in reproduction lack cornified nuptial excrescences. Scalloped skin folds are present on the outer edges of the feet, forearms and hands. The skin on the back is weakly tuberculated and that of the belly is granular.
Color in life The back varies from greyish-bronze to greenish-bronze and has a black, dark brown, or reddish mottle that generally includes dorsolaterally olive-green areas. In most individuals, there are pairs of large brown or reddish scapular marks. The armpit, groin, and posterior surface of the thighs are yellow-orange with black spots or mottled on the thighs. The anterior surfaces of the thighs are pale yellow-green with black dots. The chin and belly are white or light yellow with black dots; the ventral surfaces of the limbs are dark gray to black. The membranes are orange distally and black proximally. The iris is pale gray with fine black crosslinks.
