Blood-feeding evolution in the Nematocera. Indicated in red are the Null hypothesis (independent evolution of blood-feeding behavior in the Psychomorpha and Culicomorpha) presented in this study, according to Grimaldi and Engel (2005). Numbers at the basal branch indicate the total number of unique sialome protein families not recognizable outside Nematocera that are common to all Nematocera lineages (30 kDa antigen and 41 kDa protein family), followed by the number of all protein families (excluding the orphan proteins) unique to any Nematocera. Below the family branches with available sialome data, the numbers represents the number of protein families unique to the lineage followed by the unique families found in all members (excluding orphan proteins). Notice that the denominators shown at the end of the branches (8, 34, 8 and 24) add to the 74 unique salivary protein families. 4/8 in the sand fly branch indicate that of the 8 unique sand fly protein families, only 4 are shared between Lutzomyia and Phlebotomus. Phylogenetic and divergence date data were obtained from Grimaldi and Engel (2005).
