Gram-positive, non-spore-forming rods (strain 6401990), isolated from a human cutaneous discharge were subjected to a polyphasic taxonomy study. The only respiratory quinone was MK-7 and the major fatty acids were anteiso-C15 : 0 (34.3 %), anteiso-C17 : 0 (18.7 %) and iso-C16 : 0 (18.6 %). Mycolic acids were not present. Polar lipids present were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine and unidentified glycolipids. The isomer of diaminopimelic acid identified was -diaminopimelic acid, and the analysis of whole-cell sugars showed the presence of high amounts of galactose, ribose and some glucose. The G+C content of strain 6401990 was 68.6 %. Phylogenetic analysis based on 16S rRNA gene sequence comparisons showed 95.1 % similarity with . On the basis of phenotypic data and phylogenetic inference, it is proposed that this strain represents a novel species in a new genus of the family , for which the name gen. nov., sp. nov. is proposed. The type strain is 6401990 (CSUR P17=CIP 109418=CCUG 53859).
