Megadytes ducalis is a species of water beetle in the family Dytiscidae. It is the largest species in the family.[2] Until recently, the species was only known from a single specimen that was collected in the 19th century from Brazil,[3] but more specimens, also collected in the 19th century from Brazil, were discovered in 2019.[4] Although listed as extinct by the IUCN, the limited studies conducted on water beetles in Brazil means that it might still survive.[3]
