sp. nov. and sp. nov. isolated from wild animals and reclassification of and as comb. nov. and comb. nov., respectively.

Four Gram-stain-positive, catalase-negative, non-spore-forming, rod-shaped bacterial strains (zg-325, zg329, dk561 and dk752) were isolated from the respiratory tract of marmot () and the faeces of Tibetan gazelle () from the Qinghai-Tibet Plateau of PR China. The results of 16S rRNA gene sequence-based phylogenetic analyses indicated that strains zg-325 and dk561 represent members of the genus , most similar to DSM 20671 and B71, respectively. The DNA G+C contents of strains zg-325 and dk561 were 71.6 and 69.3 mol%, respectively. The digital DNA-DNA hybridization values of strains zg-325 and dk561 with their most closely related species were below the 70 % threshold for species demarcation. The four strains grew best at 35 °C in air containing 5 % CO on brain heart infusion (BHI) agar with 5 % sheep blood. All four strains had Cω9 and C as the major cellular fatty acids. MK-8 and MK-9 were the major menaquinones in zg-325 while MK-10 was predominant in dk561. The major polar lipids included diphosphatidylglycerol and phosphatidylinositol. On the basis of several lines of evidence from phenotypic and phylogenetic analyses, zg-325 and dk561 represent novel species of the genus , for which the name sp. nov. and sp. nov. are proposed. The type strains are zg-325 (=GDMCC 1.1724=JCM 34091) and dk561 (=CGMCC 4.7566=JCM 33484). We also propose, on the basis of the phylogenetic results herein, the reclassification of and as comb. nov. and comb. nov., respectively.
