Subspecies

Subspecies appear not to intergrade and are sometimes considered separate species, but field studies in possible contact zones, as well as molecular analyses, required in order to determine extent to which they are isolated and genetically distinct.
The following 4 subspecies are recognised:

minor Pelzeln, 1868 - Eastern Colombia (Guainía south to Caquetá), south-western Venezuela (south-western Amazonas) and north-western Amazonian Brazil (upper drainage and southern bank of middle R Negro, south to northern bank of R Ica).
