Rhizobia were isolated from their root nodules grown in their respective soils from the Succulent Karoo biome (SKB) in South Africa, identified and characterized using a polyphasic approach. Sequence analysis of the 16S rRNA gene confirmed all isolates as <i>Mesorhizobium</i> members, which were categorized into two distinct lineages using five housekeeping protein-coding genes. Lineage I included 14 strains from both legumes, while Lineage II comprised a single isolate from <i>C. sericea</i>. Differences in phenotypic traits were observed between the lineages and corroborated by average nucleotide identity analyses. While all strains nodulated their original hosts, strains from <i>C. sericea</i> failed to effectively nodulate <i>L. diffusa</i> and vice versa. Phylogenetic analyses of nitrogen fixation (<i>nifH</i>) and nodulation (<i>nodA</i>, <i>nodC</i>) loci grouped all strains in a single clade, suggesting that unique symbiotic loci determine nodulation of these legumes. We designated Lineage I and II as <i>Mesorhizobium salmacidum</i> sp. nov. (Ld1326<sup>Ts</sup>; GCA_037179605.1<sup>Ts</sup>) and <i>Mesorhizobium argentiipisi</i> sp. nov.
