Abstract
Trypanosomatids have been traditionally allocated to a number of genera tha t were described based on morphological features and host range. Recently m olecular studies have provided new data that has allowed a reexamination of the genera. While in some cases the molecular data has been in agreement w ith the morphological characters they have also reinforced existing doubts about some current generic divisions as well as raising new concerns. A rev ision of the trypanosomatid genera is required. Suggested features of such a revision would include: (1) The possible division of Trypanosoma into new genera to reflect the wide genetic diversity of this group; (2) The inclus ion of Leishmania, Sauroleishmania and Endotrypanum within a single genus g iven their high genetic affinity; (3) The complete revision of the monogene tic typanosomatid genera to reflect monophyletic groups; (4) A more precise redescription of Phytomonas so as to only include the monophyletic plant f lagellates.
