The levels of DNA-DNA relatedness among the type strains of the four validly described Saccharomonospora species ranged from 18 to 46%. Saccharomonospora viridis KCTC 9156. which was described as ′Saccharomonospora internatus′ but later reclassified as a member of S. viridis, showed a similarity level of 90% to S. viridis KCTC 9115T. Saccharomonospora sp. strain K180 exhibited levels of DNA-DNA relatedness that are indicative of a new species. Saccharomonospora azurea exhibited levels of DNA-DNA homology of 84–95% to ′Saccharomonospora caesia′ strains including the type strain. Therefore, on the basis of DNA-DNA relatedness data and taxonomic data described previously, it is proposed that ′S. caesia′ should be considered as a synonym of S. azurea. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-49-2-671
