    Trypanosoma brucei by morphology and I would guess rhodesiense by geographic location.

    T. brucei, I do not think the 2 species can be differentiated by morphology.

    Fred P - I recall seeing a map of the distribution of rhodesiense and gambiense and that there is no overlap, but I just checked the CDC website to be sure:

    "At present, there is no overlap in their geographic distribution."
