No full textA total of five polymorphic microsatellites loci from Pseudoplatystoma corruscans were isolated and characterized. A population survey involving 43 specimens resolved a large number of alleles (range seven to eight among loci) and high observed heterozygosity (0.500-0.615), indicating its usefulness in population genetics studies. Cross-species amplification was successful in four other Pimelodidae species
