FIGURE 5. Phylogenetic relationships of basal rivulid lineages, according to synapomorphies established in Costa (2004a): clade A: unossified interhyal, absence of the distal process of the second epibranchial; clade B: E­scales not overlaped, shortened uncinate process of the third epibranchial, articular face of the distal egde of the first hypobranchial anteriorly expanded, ventral process of the angulo­articular narrowed, posterior flange of the cleithrum absent.
