Brasilennea is a fossil genus of small to medium-sized air-breathing land snails, terrestrial pulmonate gastropods in the family Cerionidae. The genus is known only from the Brazilian Paleocene Itaboraí Basin, in Rio de Janeiro.[3] The most characteristic feature of the genus is its two spiral furrows on the body whorl.[3]
The name Brasilennea implies that it is a Brazilian genus that is very similar to the African genus Ennea.[2] The genus was originally classified in the family Streptaxidae,[2] but it was later transferred to the family Cerionidae.[3]
