Proposal to transfer Catellatospora ferruginea and 'Catellatospora ishikariense' to Asanoa gen. nov. as Asanoa ferruginea comb. nov. and Asanoa ishikariensis sp. nov., with emended description of the genus Catellatospora.

The taxonomic position of Catellatospora ferruginea and 'Catellatospora ishikariense' was investigated by phylogenetic, chemotaxonomic and physiological characterization. The 16S rDNA sequences of the organisms were compared with those of members of the genus Catellatospora and other genera of the Micromonosporaceae and phylogenetic trees were inferred by using distance-matrix and parsimony methods. The organisms formed a distinct cluster within the radiation of this family that was supported by a high bootstrap value, of 100%. The nearest neighbours were members of the genera Catenuloplanes and Verrucosispora. The organisms were readily differentiated from all of the validly described genera of the family Micromonosporaceae by using a battery of chemical and morphological characters, and the name Asanoa gen. nov. is proposed. On the basis of phenotypic and DNA-DNA hybridization data, Asanoa ferruginea comb. nov. (type strain IMSNU 22009T = IFO 14496T DSM 44099T) and Asanoa ishikariensis sp. nov. (type strain IMSNU 22004T = IFO 14551T) are described.
