These frogs are reddish brown to tan or gray. Sometimes there are light dorsolateral stripes. There is usually an interorbital bar, a supratympanic mark and a scapular bar, all of them black in color. The concealed surfaces of thighs are red and the venter is white. A black spot on the base of thigh and in groin can be present (by subspecies). The vomerine teeth, behind the coanes, are in transverse and long series. There is no webbing between the toes and there are no digital disks. Adult size is moderate, 43 mm in females, males are smaller.
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Cuba
This species is endemic of Cuba, Isla de la Juventud and Archipiélago de Sabana-Camaguey. This species is found islandwide, from sea level to about 4000 feet (~1200 meters) and it occurs in woods, scrubs, coffee and other plantations and in human habitations.
Life History, Abundance, Activity, and Special Behaviors
This frog is a direct developing species, ovipositing in moist soil and under rocks and fallen trunks. Clutches are composed of spherical, orange, semitransparent eggs, 3-4 mm in diameter. They are active at night, males vocalize from the ground emitting a series of bird-like twittering or clicks, similar to water dropping from a leaky faucet.
Trends and Threats
Some natural areas in Eastern Cuba have been degraded and substituted by pastures inducing the extinction of this species of its original habitat. Nevertheless, it is able to survive in areas where coffee or timber plantations have substituted natural vegetation.
Possible reasons for amphibian decline
General habitat alteration and loss
Intensified agriculture or grazing
