Fig. 2. Phylogenies used for comparative analyses. (A) Modified from the preliminary phylogeny of de Santana (C.D.d.S., unpublished data). de Santana's phylogeny is a majority consensus from 597 most parsimonious trees in a maximum parsimony analysis of 103 morphological characters. (B) Modified from Crampton and Albert (Crampton and Albert, 2006). Scale bar applies to branch lengths. Note that we use the older name Sternarchogiton porcinum whereas this species is referred to as `Apteronotus' porcinum in Crampton and Albert (Crampton and Albert, 2006). Note differences between the two phylogenies in the placement of S. terminalis, S. nattereri and S. porcinum and in the relationship between A. albifrons and A. leptorhynchus.
