Panamanian golden frog, is a small, brightly-coloured frog. Wet forest males and females are larger than those that live in dry forest habitats. The head is longer than broad, with a pointed, protuberant snout. The pupil is horizontally elliptical. There is no tympanum, but the inner ears are well-developed. The body is slim with long limbs, and the upper surface is smooth. The fingers are elongate and narrow. The toes are extensively webbed. Males also have a well-developed brownish nuptial pad on the upper and inner surface of the first finger.
The sexes have similar colouration, usually uniform golden yellow with one to several large black dorsal markings. They have yellow abdomens.
This species changes colour as they age. Juveniles are green and black. As they mature, they gradually gain the adults’ yellow colouration. Adult males measure 35-48 mm and weigh 3-5 g; adult females measure 45-63 mm and weigh 4-7 g.
