A phylogenetic analysis of the genus Catellatospora based on 16S ribosomalDNA sequences, including transfer of Catellatospora matsumotoense to the genus Micromonospora as Micromonospora matsumotoense comb. nov.

Phylogenetic studies based on the 16S ribosomal gene sequences showed that members of the genus Catellatospora revealed phylogenetic heterogeneity wit hin the Family Micromonosporaceae as well as a heterogeneous menaquinone co mposition. Among them, Catellatospora matsumotoense was closely related to members of the genus Micromonospora, indicating that this organism should b e excluded from the genus Catellatospora. On the basis of classical taxonom ic characteristics and phylogenetic evidence, Catellatospora matsumotoense is proposed to be transferred to the genus micromonospora as M. matsumotoen se comb. nov.
