It is endemic to Alto del Buey mountain in the Serranía del Baudó range, in the Chocó Department of western Colombia.

[4] The holotype, an adult female, measured 17 mm (0.67 in) in snout–vent length.

[3] Its natural habitat is humid pre-montane forest at elevations of 980–1,070 m (3,220–3,510 ft) above sea level.

[1] The tadpoles probably live in aroid leaf axils—almost all axils near the summit of Alto del Buey contained a tadpole, but it is not certain that they were this species, as opposed to Andinobates minutus.

[3] This frog has a very restricted range, and there is risk of habitat loss caused by smallholder agricultural activities, logging, and human settlement.
