An actinomycete isolated from an immunocompetent patient suffering from confluent and reticulated papillomatosis was characterized using a polyphasic taxonomic approach. The organism had chemotaxonomic and morphological properties that were consistent with its assignment to the genus and it formed a distinct phyletic line within the 16S rRNA gene tree. It shared a 16S rRNA gene sequence similarity of 98.3 % with its nearest neighbour, the type strain of , and could be distinguished from the type strains of all species using a combination of phenotypic properties. It is apparent from genotypic and phenotypic data that the organism represents a novel species in the genus . The name proposed for this taxon is ; the type strain is N 1280 (=DSM 44961=NCIMB 14145).
