  abstract = {{P}seudoplatystoma species are highly prized {S}outh {A}merican {P}imelodid migratory catfishes. {U}ntil recently, their taxonomy was not clearly established, with discrepancies between morphological and molecular analyses. {H}ere, {P}seudoplatystoma species from the {P}eruvian {A}mazon were characterized at the molecular level from a sample representing the observed range of their color pattern variations in the study area. {A}nalyses were performed using seven microsatellite loci for 103 specimens and, for part of them (52), using sequences of two regions of their mitochondrial genome [{C}ytochrome {O}xidase subunit {I} ({COI}) and {C}ontrol {R}egion ({CR})]. {F}actorial correspondence analysis and assignment tests based on microsatellite polymorphism showed that the specimens originally identified as {P}. punctifer belonged to two different gene pools highly differentiated from {P}. tigrinum. {M}orphological examination identified two different morphotypes (with and without black stripes), suggesting the existence of two distinct taxa within {P}. punctifer. {T}his result was corroborated by the {ML} tree based on {CR} sequences, where all individuals but four clustered in a similar way as in the {FCA} and {B}ayesian assignment tests. {F}or these four individuals, mitochondrial introgression or retention of ancestral polymorphism was likely. {I}n contrast, the {ML} tree based on {COI} sequences showed that reciprocal monophyly was not yet achieved for this marker for the two {P}. punctifer taxa. {T}he existence of three sympatric species of {P}seudoplatystoma in the {P}eruvian {A}mazon is discussed in relation to their molecular characteristics, color patterns and ecology. {E}volutionary scenarios regarding their divergence are hypothesized.},
