Would very much appreciate a copy of this one.

Abstract

The Characidae is the most diverse family of Neotropical fishes, currently encompassing more than one thousand valid species.
Some subgroups within this family still lack phylogenetic definitions, being diagnosed on the basis of combination of
characters, a common procedure in pre-cladistic studies. Agoniatinae, currently composed by two valid species, Agoniates
anchovia and A. halecinus, is one of them. In the present study the Agoniatinae is redefined using a phylogenetically oriented
comparative survey that included the two Agoniates species plus 114 species representing all the major clades of the Characidae
and their closest relatives. Six derived morphological characters are identified as synapomorphies for the Agoniatinae:
deep notch on the posterior region of the maxilla joining the ventral margin of the infraorbital 2; dentigerous portion of premaxilla
shorter than the ascending process of this bone; dentary canine preceded by tricuspid teeth; ventral margin of the
urohyal markedly convex; base of the uppermost ray of the ventral lobe of the caudal fin much expanded, being as deep as
the distal margin of hypural 2; and levator arcus palatini muscle with a posterodorsal bundle of fibers attaching to the dorsal
face of the sphenotic spine.
