• A Gram-positive, acid-fast, aerobic, rapidly growing and non-motile strain was isolated from lead–zinc mine tailing sampled in Lanping, Yunnan province, Southwest China. 16S rRNA gene sequence analysis showed that the most closely related species of strain KC 300 T was Mycolicibacterium litorale CGMCC 4.5724 T (98.47 %). Additionally, phylogenomic and specific conserved signature indel analysis revealed that strain KC 300 T should be a member of genus Mycolicibacterium , and Mycobacterium palauense CECT 8779 T and Mycobacterium grossiae DSM 104744 T should also members of genus Mycolicibacterium . The genome size of strain KC 300 T was 6.2 Mb with an in silico DNA G+C content of 69.2 mol%. Chemotaxonomic characteristics of strain KC 300 T were also consistent with the genus Mycolicibacterium . The average nucleotide identity, digital DNA–DNA hybridization and average amino acid identity values, as well as phenotypic, physiological and biochemical characteristics, support that strain KC 300 T represents a new species within the genus Mycolicibacterium , for which the name Mycolicibacterium arseniciresistens sp. nov. is proposed, with the type strain KC 300 T (=CGMCC 1.19494 T =JCM 35915 T ). In addition, we reclassified Mycobacterium palauense and Mycobacterium grossiae as Mycolicibacterium palauense comb. nov. and Mycolicibacterium grossiae comb. nov., respectively.
