Abstract: The species Hoplias malabaricus is a predator fish found in nearly all cis-Andean basins. From a cytogenetic point of view, this species comprises, at least, seven differentiated karyomorphs. Several localities have been formerly analyzed in Brazil, however, some regions, such as Bahia State, remain underrepresented. Recently, the Brazilian Environment Ministry classified both Itapicuru and Contas river basins (entirely located within Bahia territory) as priority conservation areas, whose biodiversity status l… Show more

“…According to Jacobina et al (2009), the presence of endemic species in some of the drainages of eastern Brazil indicates the existence of biogeographic units or subprovinces in the area, though the pattern of subdivision is complex. Two subprovinces in the Brazilian eastern coastal area were proposed by Bizerril (1994), and termed "subprovince of the southeast coast" (from 'Mountainous region' of Rio de Janeiro State to the south of Santa Catarina State) and "subprovince of the east coast" (from coastal basins in Bahia south of the rio São Francisco outlet to rio Paraíba do Sul basin = very similar to NMAF ecoregion).…”

“…Their variation and diversity may be present at different levels, such as intra-population polymorphisms (e.g. Gymnothorax vicinus, Vasconcelos and Molina, 2009), interpopulation polymorphisms, such as in Hoplias malabaricus (Jacobina et al 2009) and Leporinus elongatus (Molina et al 2008) or interspecific diversification (Moreira-Filho and Bertollo, 1991).…”

“…Molecular and cytogenetic data indicate that at least some coastal populations are related to other populations in the continental Paraná Basin (Dergam et al, 1998(Dergam et al, , 2002Lemos et al, 2002;Vicari et al, 2005Vicari et al, , 2006Santos et al, 2009). In northern populations, H. malabaricus from the coastal basins of the Itapicuru and Contas rivers share the same karyomorph (40F) with most populations from the São Francisco Basin (Bertollo et al, 2000;Jacobina et al, 2009), and some from the eastern Amazon (Bertollo et al, 2000).…”
