Given the relatively small amount of remaining forest fragments of its native habitat in Colombia , due primarily to agricultural expansion and pastures for cattle, further efforts are needed to ensure adequate conservation of the few species known. Additional sampling efforts are also needed to discover if there are any other species present along its potential distribution range.
