Phlegethontia is an extinct genus of aïstopod tetrapodomorphs from the Carboniferous and Permian periods of Europe and North America.^[1]

It was about 1 metre (3.3 ft) long, and possessed a lightly built skull with many openings, unlike some earlier relatives.^[2]

"Dolichosoma" longissima, named by Antonin Fritsch in 1875, has been reassigned to the genus Phlegethontia and is now considered to be P. longissima.^[3]^[4] "Dolichosoma" has been considered to be a nomen nudum because the holotype was inadequately described through a layer of matrix by Thomas Henry Huxley in 1867.^[5]^[6]
