The Lovely Poison Frog is a small, diurnal terrestrial frog, measuring about 2.5 cm in length. Its body is black with two bright yellow to orange longitudinal stripes on the back, and blue-green marbling on the flanks and limbs. This species inhabits lowland humid forests, often near slow-moving streams, between 10 and 650 m elevation. It primarily feeds on small invertebrates such as ants and spiders. Although its skin contains toxic alkaloids, including batrachotoxins, their concentration is low and sometimes undetectable. The Lovely Poison Frog is listed as Least Concern by the IUCN, but is locally threatened by deforestation and pollution.
