Node 190: Bryconinae (86 / 97 / 1 / 10)

Genera Brycon , Chilobrycon Géry & de Rham , Henochilus Garman , Lignobrycon , and Triportheus .

The subfamily Bryconinae was considered by Géry (1977) to be composed of the tribes Bryconini, Salminini , and Triportheini. Although a close relationship between Brycon and Triportheus has been suggested several times in the literature ( e. g. Géry, 1977), only Malabarba (1998b) obtained evidence supporting this hypothesis. In her phylogeny, Lignobrycon is the sister group of Triportheus , supported by eight synapomorphies. Lima (2003b), mainly based in the analysis of Zanata (2000) restricted the Bryconinae to Brycon , Chilobrycon , and Henochilus , leaving Lignobrycon , Salminus , and Triportheus as incertae sedis within the Characidae ( Lima et al., 2003). This subfamily is herein redefined to include the previously incertae sedis genera Lignobrycon and Triportheus . The included species of Brycon form a polytomy in this node, and the monophyly of the genus is not supported in this analysis. However, only a small sample of this genus was analyzed, and a study focused on the question of the monophyly of Brycon lies far beyond the scope of this paper.

Synapomorphies:

1. Interdigitations between premaxillae (103): (1> 0) present. Paralleled in Distichodus maculatus and Piaractus mesopotamicus .

2. Number of rows of premaxillary teeth (123): (0> 1) three. Paralleled in Bryconaethiops macrops and Chalceus macrolepidotus .

3. Polymorphism of teeth on inner premaxillary row (131): (0> 1) present, with two medial teeth somewhat larger and usually separated from remaining ones by a gap. Paralleled in the Serrasalmidae .
