DISTRIBUTION: Much of eastern South America, from Venezuela (?) east and 
south through Brasil to central Bolivia, southeast into northeastern 
Argentina. 
SUBSPECIES: None to possibly nine. I do not recognize subspecies of this 
taxon because of the mosaic nature of the variation examined thus far. Note 
that there are three senior synonyms for the name poecilogyrus. Any use of a 
senior synonym would upset the stability of the long, continued use of 
poecilogyrus in the literature, and I recommend none be used.
