Khaki bromeliad frog yellow chromatophores. The vocal sac is grey to black. The male call is a two-note call, the second note being higher than the first one, and is preceded by about 4–5 warm-up notes. Calling sites are in trees, above the ground, probably also higher.

It is threatened by habitat loss, particularly from felling large trees. It occurs in the Sierra de Bahoruco National Park in the Dominican Republic. Khaki bromeliad frog The khaki
