FIGURE 7 in Molecular systematics of Serrasalmidae: Deciphering the identities of piranha species and unraveling their evolutionary histories
FIGURE 7. Phylogenetic trees of serrasalmids inferred from ribosomal (A) and control region (B) data sets, both including original material and GenBank sequences. Parsimony bootstrap percentages are shown above branch nodes, while proportions (>50%) of trees possessing a given clade in Bayesian posterior distributions are shown below. Taxa shared by both trees are in bold font. Specimen sequences from original material appear in shadow boxes, preceding numbers (1-33) correspond to numbered specimens and information presented in Table 1 and elsewhere. GenBank sequences are followed by gb. Taxa with VNTR in control region marked by an "R" and reconstruction of presence of VNTR shown in blue. GenBank (gb) species with asterisk (*) indicate taxa of which we question the identification.

FIGURE 1 in Molecular systematics of Serrasalmidae: Deciphering the identities of piranha species and unraveling their evolutionary histories
FIGURE 1. Alternative hypotheses of serrasalmid relationships: (A) Machado-Allison (1983, 1985), based on morphology, divides family into two major clades; (B) Machado-Allison et al. (1989) revised piranha clade showing the position of Pristobrycon striolatus if absence of pre-anal spine is considered to be primitive character (arrow indicates occurrence of this trait); (C) Ortí et al. (1996), based on mitochondrial ribosomal RNA sequence data, defines three major clades. Upper tree includes 13 of the currently 15 recognized genera, lower tree includes 11 genera. Note: the genus Tometes was presented in original tree of Ortí et al. (1996) as "N. gen. A" (P. Petry, pers. comm. 2005). The authors also stated that specimens assigned by Machado-Allison (1982, 1983) to Utiaritichthys do not belong to that genus, apparently suggesting the specimens are Tometes.
