Phlegethontia is anextinct genus ofaïstopod tetrapodomorphs from theCarboniferous andPermian periods of Europe and North America.^[1]

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

"Dolichosoma" longissima, named byAntonin Fritsch in 1875, has been reassigned to the genusPhlegethontia and is now considered to beP. longissima.^[3]^[4]"Dolichosoma" has been considered to be anomen nudum because theholotype was inadequately described through a layer of matrix byThomas Henry Huxley in 1867.^[5]^[6]
