[UNIFESP]; Hallerman, Eric M.; Hilsdorf, Alexandre W. S.The long-whiskered catfish Steindachneridion parahybae (Family Pimelodidae) is endemic to the Paraiba do Sul River basin in southeastern Brazil. This species was heavily exploited by artisanal fisheries and faces challenges posed by dams, introduced species, and deterioration of critical habitat. The remaining populations are small and extirpated from some locales, and the species is listed as critically endangered in Brazil. Screening variation at a partial mitochondrial control region sequence (mtCR) and 20 microsatellite loci, we: (i) describe the patterns of genetic diversity along its current distributional range
