The most conspicuous characteristic of the species is a brown triangular marking between the eyes of most individuals; yellow or orange posterior surfaces of the thighs, with prominent vertical brown or black bars ( Duellman 2001 ). A total of 6 individuals were observed between 260 and 300 m , on leaves of vegetation in water bodies and grasslands close to wet forest relicts, in Sta- tion 5. The species is distributed from Panamá to Guyana and Surinam , and in Colombia , it is present in the inter-Andean valleys, the Chocó biogeographic zone and along the savannas in the north, up to the Sierra Nevada de Santa Marta ( Acosta-Galvis 2019 , Suárez and Alzate Basto 2014 ).
