South America: found only in north-western Brazil north of the Amazon and west of Río Negro.


This is a monotypic species[1].


Seasonally flooded woodland where it is found in understory. Occasionally found in secondgrowth.


Very little is known; insects are expected to be important food items.

Supposedly a quiet species not moving much so easy to overlook.
