Description
Males measure 16–19 mm (0.63–0.75 in) and females 17 mm (0.67 in) in snout–vent length (based on only four and two specimens, respectively). It differs from related Ecuadorian species by not having webbing between its toes and by lack of oblique lateral stripe (sometimes a short stripe is present) and a pale dorsolateral stripe. Male call is a single, sharp "peep".
Habitat and conservation
This species is known from very humid premontane and low humid montane forest. One male was collected from a bromeliad. Its altitudinal range is 1,760–2,430 m (5,770–7,970 ft) asl. It is threatened by habitat loss and degradation caused by agricultural expansion and logging.
