See Taeger (2002) for current taxonomy. of the genus. Species of Megalodontes removed from the British and Irish list: [ Megalodontes panzeri (Leach, 1817), Megalodontes plagiocephalus (Fabricius, 1804)] Up to three separate Megalodontes species have at times been considered to have been present in England. Neither Megalodontes panzeri nor Megalodontes plagiocephalus , on the basis of their currently known distributions and habitat requirements, probably ever occurred in the British Isles.
