This species is known only from the type locality, at Cerro Jaua (04° 49' 55''N; 64° 25' 59''W), in Bolívar State, Venezuela, at 1,600m asl. It might also occur at lower altitudes on the slopes of Cerro Jaua, but this requires confirmation. It is probably a slope-loving species, and is likely to occur more widely.
