Última Hemigrammus ataktos: a new species from the rio Tocantins basin, central Brazil (Characiformes: Characidae) Neotropical Ichthyology Marinho,Manoela M. F.; Dagosta,Fernando C. P.; Birindelli,José L. O.. A new species of Hemigrammus is described from the middle rio Tocantins basin, central Brazil. The new species can be distinguished from all congeners by having a black midlateral stripe on the body extending from the posterior margin of the eye to the median caudal-fin rays. Mature males possess dorsal-, pelvic-, and anal-fin rays elongate, features that also help to recognize the new species. Although the new species is described in Hemigrammus, some specimens present a complete series of pored scales in the lateral line. A discussion about the generic allocation of the new species is presented. Tipo: Info:eu-repo/semantics/article Palavras-chave: Lateral line; Neotropical fish; Systematics; Taxonomy; Tetras.

During studies carried out with a small characid (Astyanax scabripinnis), from the Brazilian streams located in Cerrado biome, some gonads of fishes exhibited sparse oocytes in perinucleolar stage embedded in normally developing testicular tissues. Another pattern of gonad intersex with vitellogenic oocytes and mature lobules was observed in the gonads of fishes collected from a reservoir supplied by the Atlantic Forest stream. These gonads in different stages of maturation were examined histologically. The results revealed the patterns occurring in fishes of the same species, from four different populations.
