Following Soula (2005), all specimens found in countries outside the research area are now assigned to subspecies not occurring in the Guianas. Unfortunately, Soula (2005)does not mention the distribution of the nominal subspecies except for the typespecimen, which was collected in Guyana. Because of this omission, we have elected to include here the full distribution of the species as given by earlier authors, even as this subspecies is still only known to occur in Guyanaand Suriname.
