Figure 4.

Chromosomal data plotted on a phylogenetic tree adapted from Harvey et al. [6]. The diploid numbers (2n) for Rhynchocyclidae and Platyrinchidae are based in the data obtained to Tolmomyias sulphurescens (present study) and Platyrinchus mystaceus [13]. The 2n for Tyrannidae is considered as ~80 because most of the species karyotyped so far in this family have approximately 80 chromosomes (Table 1).
