Proposed as a subspecies of Macroglossum corythus.
In habitus, other than being generally smaller, Macroglossum corythus fuscicauda is all but indistinguishable from the western Macroglossum corythus corythus. It is provisionally maintained here as a separate subspecies only because of the large geographical gap between the two taxa, but it is recognized that this does not provide a scientific justification.
