clade Euthyneura clade Panpulmonata clade Eupulmonata clade Stylommatophora Strophocheilus sanctijosephiMegalobulimus sanctijosephiCarinifex fluminensisVorticifex fluminensis Eoborus sanctijosephi is a fossil species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Strophocheilidae, from the Paleocene Itaboraí Basin, Brazil.

Its name makes reference to the place of discovery: the São José de Itaboraí municipality, where Itaboraí Basin is located.

[2] The species was originally described as Strophocheilus sanctijosephi, but was later transferred to the genus Eoborus.

[3] The species Vorticifex fluminensis (Brito, 1967) was considered to be the fragment of the spire top of E. sanctijosephi and, thus, its synonym.
