This is a type of poison dart frog, a group that has given rise to many chemicals found to be useful to humans.
This species is less poisonous than its brightly coloured relatives.
This is a small species, which lives in and around streams and probably does not grow larger than 3 cm in total length.
It only has been discovered in November 2010 and it may well be an endemic species for this part of the western Andes.
