''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.〔Salvador, R.B.; Rowson, B.; Simone, L.R.L. 2011. Rewriting the fossil history of Cerionidae (Gastropoda: Pulmonata): new family assignment of the Brazilian Palaeocene genus Brasilennea Maury, 1935. Journal of Molluscan Studies 77: 445–447. 〕 The most characteristic feature of the genus is its two spiral furrows on the body whorl.〔 The name ''Brasilennea'' implies that it is a Brazilian genus that is very similar to the African genus ''Ennea''.〔 The genus was originally classified in the family Streptaxidae,〔 but it was later transferred to the family Cerionidae.〔 == Species == Species within the genus ''Brasilennea'' include: * ''Brasilennea arethusae'' Maury, 1935〔 - type species of genus * ''Brasilennea guttula'' Salvador & Simone, 2012〔Salvador, R.B. & Simone, L.R.L. 2012.
