This catfish is endemic to the Brazilian state of Pará where it has been recorded from the lower Amazon River, near the mouth of the Tapajós River, the Pará River, and the lower Tocantins River.

This species reaches a standard length of and is believed to be a facultative air-breather. The specific name, pumila, is Latin and means "dwarfish", an allusion to teh small adult size of this fish.
