          Abstract

          New records of Hemigrammus ora Zarske, Le Bail & Géry, 2006, previously believed to be endemic to the French Guiana drainages, are confirmed for Brazilian drainages. The species is reported from the Tocantins-Araguaia system and lower Amazon River. Morphometric and meristic data, previously undescribed morphological traits related to caudal-fin squamation and anal-fin hooks, and geographic variation are presented for the species.

          Phylogeny of the family Characidae (Teleostei: Characiformes): from characters to taxonomy

          Juan Marcos Mirande (2010)
          The family Characidae is the most diverse among Neotropical fishes. Systematics of this family are mainly based on pre-cladistic papers, and only recently a phylogenetic hypothesis for Characidae was proposed by the author. That phylogeny was based on 360 morphological characters studied for 160 species, including representatives of families related to Characidae. This paper is based on that phylogenetic analysis, with the analyzed characters described herein and documented, accompanied by comparisons of their definition and coding in previous papers. Synapomorphies of each node of the proposed phylogeny are listed, comparisons with previous classifications provided, and autapomorphies of the analyzed species listed. Taxonomic implications of the proposed classification and the position of the incertae sedis genera within Characidae are discussed. A discussion of the phylogenetic information of the characters used in the classical systematics of the Characidae is provided.
