The catfishes Brachyplatystoma flavicans (n=49) and Pseudoplatystoma fasciatum (n=69)showed comparable low allozyme diversities (He=0.012 and 0.009-0.028, respectively), butcontrasting PCR-RFLP restriction site mitochondrial DNA diversities (three haplotypes:p=0.034-0.092 and five haplotypes: p=0.001-0.023, respectively) in the Rio Ichilo andBeni (Bolivia). Genetic homogeneity between samples was high for B. flavicans and lower forP. fasciatum. Based on mitochondrial diversity, both species probably experienced a historicpopulation reduction but at different time scales.
