Molecular systematics of the neotropical shovelnose catfish genus Pseudoplatystoma Bleeker 1862 based on nuclear and mtDNA markers

► Molecular phylogenies for mitochondrial and nuclear genes are used to assess differentiation among species and the phylogeny of South American catfshes in the genus Pseudoplatystoma. ► Genetic divergence and coalescent analysis suggest the existence of four rather than eight putative species in this genus. ► The trans-Andean species Pseudoplatystoma magdaleniatum is placed as the sister species in this clade.
