Ultrastructural changes in female hepatocytes during ovarian maturation of Steindachnerina insculpta (Pisces: Curimatidae) [PDF]
Brazilian Journal of Biology, 2006 During gonadal maturation the females of Steindachnerina insculpta, a teleost of the Furnas reservoir, Minas Gerais, Brazil, show low hepatosomatic and high gonadossomatic indexes, suggesting possible transference of hepatic substances to the ovaries.

New Steindachnerina Species (Teleostei: Characiformes: Curimatidae) from the Rio Tocantins Drainage
Copeia, 2009Abstract A new species, Steindachnerina notograptos, is described from the middle portions of the Rio Tocantins drainage, Brazil. The possession of a small, fleshy, lobulate body situated on each side of the posterior limit of the medial fold of the buccopharyngeal complex is autapomorphic for S. notograptos.

Biologia alimentar de Steindachnerina brevipinna (Characiformes, Curimatidae) do rio Ibicuí-mirim, Rio Grande do Sul, Brasil [PDF]
Iheringia - Serie Zoologia, 2003 The feeding biology of Steindachnerina brevipinna (Eigenmann & Eigenmann, 1889) is described based on specimens collected in the Ibicuí-Mirim river, Rio Grande do Sul, Brazil, from April 2001 to March 2002. Diet description is based on the analysis of the frequency of occurrence and index of dietary importance of the ingested items.

Whereas four species of the genus Steindachnerina occur in the Paraná river basin, S. insculpta was the only endemic species of the region under analysis, which is the third lower section of the upper Paraná river. Among other factors, this species has been characterised by the absence of spots in the basal region of the dorsal fin.

Abstract A new species of Steindachnerina, family Curimatidae, is described from the headwaters of the Rio Jamanxim in the central portion of the Rio Tapajos basin of the Brazilian Amazon. The species is distinguished from its congeners on the basis of pigmentation and various meristic and morphometric features.

B chromosomes are additional elements to standard karyotypes observed in different species of fishes, especially in Curimatidae. However, despite studies demonstrating the occurrence of Bs, little is known about their origin and evolution. To better understand the genomic composition and evolutionary processes involving B chromosomes, microdissection ...
