Última Revisão taxonômica e relações filogenéticas das espécies de Roeboides grupo-microlepis (Ostariophysi, Characiformes, Characidae) Iheringia, Sér. Zool. Lucena,Carlos Alberto Santos. The Roeboides microlepis species-group is revised. Four species are recognized: R. myersii Gill, 1870 from the Amazon basin, R. microlepis (Reinhardt, 1851) from river Paraguay, middle and lower river Paraná, R. araguaito sp. nov. from the river Orinoco basin, and R. margareteae sp. nov. known only from Rio Parnaíba and Pindaré-Mearim, northeastern Brazil. The type-locality of R. microlepis is restricted to river Paraguay; R. bonariensis (Steindachner, 1879) is considered a synonym of R. microlepis. The phylogenetic analysis indicates that R. myersii and R. araguaito are most parsimoniously related and may be a sister group. These two species are here considered as sister group of the monophyletic lineage which includes R. microlepis and R. margareteae. A...

Ano: 2003 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0073-47212003000300008 Diet and dental development of three species of Roeboides (Characiformes: Characidae) Neotropical Ichthyology Novakowski,Gisele Caroline; Fugi,Rosemara; Hahn,Norma Segatti. Lepidophagy has been recorded in various species of Roeboides. In this study we analyzed ontogenetic variation in diet and dental development of three Roeboides species (R. paranensis, R. prognathus and R. microlepis). Roeboides paranensis consumed mainly insects, scales and microcrustaceans, and the smaller individuals (<3.4 cm - SL) consumed mostly insects. Scale were only consumed by individuals greater than 3.4 cm. Scales were the dominant item in the diet in all sizes of R. prognathus. The diet of R. microlepis was composed primarily of whole fishes, however, the smaller individuals (<5.4 cm) consumed only insects. During ontogeny, exterior migration of teeth in the mouth started at 3.7 cm in R. paranensis and 6.5 cm in R. microlepis. As body...
