Reclassification of Nocardioides basaltis Kim et al. 2009 as a later synonym of Nocardioides salarius Kim et al. 2008, and emendation of the species description.

The taxonomic relationship between Nocardioides salarius CL-Z59(T) and Nocardioides basaltis J112(T) was established. The 16S rRNA gene sequences of the type strains showed 99.6 % similarity. The ΔT(m) for genomic DNA-DNA hybridization of N. salarius CL-Z59(T) and N. basaltis J112(T) was 0.6-1.6 °C, indicating that both strains belong to a single species. Phenotypic and chemotaxonomic characteristics showed no pronounced differences between the two species. Based on the results of the polyphasic approach, it is proposed that N. basaltis J112(T) is a later heterotypic synonym of N. salarius CL-Z59(T). An emended description of the species N. salarius is given.
