Phylogeography of the ancient catfish family Diplomystidae: Biogeographic, systematic, and conservation implications.

Highlights: [•] First molecular phylogenetic reconstruction within the ancient catfish family Diplomystidae. [•] Results show inconsistencies with traditional systematic view. [•] Phylogeographic patterns suggest that different processes have occurred to populations from Pacific and Atlantic basins. [•] High inter-basin genetic structure suggests conservation efforts at the basin level. [Copyright &y& Elsevier]
