A brown–orange-pigmented, non-spore-forming, coccus-shaped actinomycete, designated S2-20, was isolated from desert sand from Xinjiang Province in China. The isolate stains Gram-positive, is motile and produces a brownish diffusible pigment. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain S2-20 was phylogenetically affiliated to the genus , and the sequence similarity to the type strains of species was less than 96 %, making it clear that strain S2-20 represents a species that is separate from recognized species. Its major fatty acid was anteiso-C. The major menaquinone was MK-9(H). Whole-cell hydrolysates of strain S2-20 contained -diaminopimelic acid, arabinose and galactose. The DNA G+C content was 77.8 mol%. On the basis of phylogenetic, phenotypic and chemotaxonomic characteristics, strain S2-20 should be classified within a novel species of the genus , for which the name sp. nov. is proposed. The type strain is S2-20 (=CCTCC AB 207179 =KCTC 19474).
