Karyotypic comparisons in Astyanax altiparanae The karyotypic data obtained from both populations indicate a conservativeness in diploid number. Similar to previous cytogenetic studies in Astyanax altiparanae (Fernandes & Martins-Santos, 2004), the present report also verified a diploid number of 50 chromosomes for these two populations.

Autapomorphy of Astyanax abramis: 1. Length of medial bony ridge of opercle (170): (1> 0) 60% or greater than opercular length. Paralleled in the Serrasalmidae, in node 210, and in Creagrutus cf. taphorni, Hoplias cf. malabaricus, and Roeboides microlepis. Some trees: Paralleled in Acestrorhynchus pantaneiro and Salminus brasiliensis.

Autapomorphy of Astyanax asuncionensis: Some trees: 1. Form of fourth infraorbital (67): (0> 1) longer dorsoventrally than longitudinally. Reversal of synapomorphy 2 of node 260. (some trees under k9-14). Paralleled in Astyanax cf. asuncionensis.
