Phylogenetic maximum likelihood tree representing the evolutionary history of concatenated genes related to GPI anchor biosynthesis. Bootstrap values (1000 replications) greater than 80% are represented by a green circle in the branches of the tree. The right-hand panel classifies species according to their geographical range, number of sand fly species reported to act as vector for each parasite (at the species level), host preference and clinical form of the disease for species that are infective for humans. Colored dashes indicate the subgenus for each species, with those not classified into this taxonomic rank grouped as “Others”. The metadata were extracted from Akhoundi et al.
