Two rhizobial strains, Br3407 and Br3405, were isolated from nitrogen-fixing nodules on the roots of , a legume tree native to Brazil. On the basis of 16S rRNA gene sequence similarities, both strains were shown previously to belong to the genus . A polyphasic approach, including DNA–DNA hybridizations, pulsed-field gel electrophoresis of whole-genome DNA profiles, whole-cell protein analyses, fatty acid methyl ester analysis and extensive biochemical characterization, was used to clarify the taxonomic position of these strains further; the strains are here classified within a novel species, for which the name sp. nov. is proposed. The type strain is strain Br3407 (=LMG 24235 =BCRC 17587).
