| Abstract: | The results of comparative analysis of two phylogenetic trees of the trypanosomatids based on morphological and molecular characters are discussed. The morphological dendrogram was based on 33 ultrastructural characters, 6 light microscope characteristics and 8 biological characters. Molecular UPGMA dendrogram depicting differences (Dice distance) between examined trypanosomatids is based on the universally primed PCR polymorphisms. The general topology of both dendrograms are similar, with the Trypanosoma at the base. The genus Wallaceina appears to be monophyletic. In a contrary, the genera Leptomonas, Crithidia and Herpetomonas look like artificial groups according to both methods used. The cyst-forming homoxenous trypanosomatids from insects represent a monophyletic clade, which seems to be a separate genus. Two species of within genus Wallaceina are arranged as a separate subgenus. |
