Prostherapis femoralis Barbour, 1905 (junior homonym of Prostherapis femoralis Boulenger, 1884 Prostherapis boulengeri Barbour, 1909 Phyllobates boulengeri (Barbour, 1909) Colostethus boulengeri (Barbour, 1909) Dendrobates boulengeri (Barbour, 1909) Ameerega boulengeri (Barbour, 1909) The marbled poison frog or marbled poison-arrow frog (Epipedobates boulengeri) is a species of frog in the family Dendrobatidae found in western Colombia (Cauca, Nariño, Valle del Cauca Departments, including Gorgona Island) and northwestern Ecuador, at elevations of 10–1,500 m (33–4,921 ft) asl.

[4][5] Diet is varied and includes mites, ants, coleopterans, dipterans, homopterans, and colembolas.

Scientists note that it is tolerant to habitat disturbance.

Scientists noted the presence of the fungus Batrachochytrium dendrobatidis on this frog but they did not note any specimens who were sick with the corresponding fungal disease chytridiomycosis, which kills frogs.

This animal shows some presence on the international pet trade, but scientists do not know if this is a danger to the frog or not.
