| History | |
| Physical description | Males 17-19 mm., females 19-22 mm. The back and limbs are finely granular, brown, with or without black spots. The flanks are black, bordered by a narrow white or cream dorsolateral line extending from the tip of the snout to the groin. A white or cream labial stripe does not extend onto the arm. The venter is blue with black reticulations. Yellow-orange oval spots are present on the ventral surfaces of the arms, inner surfaces of the shanks, and in the groin. The iris is dark brown. |
| Distribution | Amazonian lowlands of Brazil, eastern Bolivia, and possibly French Guiana. |
| Biotope | This species is mainly found on fallen palm trees and branches in small gaps in the forest. |
| Care and breeding | They can be kept at a temperature of 25-27°C. The territorial call is a long series of short notes "peep-peep-peep-peep-peep"; the courtship call is similar, but consists of only three notes. females produce 6-33 pigmented eggs. While being transported from land to water, tadpoles are arranged symmetrically on the backs of males. The tadpoles are brown with a depressed body, long tail and mid-dorsal eyes oriented anterolaterally. The tail fins are shallow, highest at midlength; the dorsal fin does not extend onto the body. |
