Lepidosirenidae
Lepidosirenidae is a family of lungfish containing the genera Lepidosiren (the South American lungfish) and Protopterus (the African lungfish). Both genera were formerly thought to represent the distinct families Lepidosirenidae and Protopteridae within the order Lepidosireniformes, but a 2017 study analyzing all post-Devonian lungfish taxa found them to be better classified as different genera in a single family.
