Actinomycete strain MCCC 1A01550, isolated from the national mangrove reserve in Fujian Province, China, was determined to belong to the genus based on a polyphasic approach. The cell wall of the novel strain contained -diaminopimelic acid and galactose. The predominant menaquinones were MK-9(H) and MK-9(H) and the major fatty acids were iso-C, 9-C and C. The diagnostic phospholipid was phosphatidylethanolamine. The DNA G+C content of the novel strain was 71.6 mol%. Phylogenetic analysis of 16S rRNA gene sequences confirmed the separation of the novel strain from recognized members of the genus available in public databases. DNA–DNA relatedness values between strain MCCC 1A01550 and the type strains of three related species ranged from 21.29 % to 43.38 %. Based on its phenotypic and genotypic characteristics, strain MCCC 1A01550 (=DSM 41903=CGMCC 4.3534) represents the type strain of a novel species, for which the name sp. nov. is proposed.
