    Two marine actinobacteria strains, HNM0983 T and HNM0986 T , were isolated from stony coral samples collected from the coastal area of Hainan Island. The 16S rRNA gene sequence analysis revealed that these two strains are putatively novel taxa of the genus Saccharopolyspora. Whole genome sequencing comparisons further confirmed the two strains as belonging to two novel Saccharopolyspora species which can be distinguished phenotypically and chemically from their current closest phylogenetic relatives. Consequently, Saccharopolyspora montiporae sp. nov. (the type strain =HNM0983 T =CCTCC AA 2020014 T = KCTC 49526 T ) and Saccharopolyspora galaxeae sp.nov. (the type strain =HNM0986 T =CCTCC AA 2020011 T =KCTC 49524 T ) are proposed as the name for the new strains, respectively. We compared some genomic information of the genus Saccharopolyspora, especially the biosynthetic gene clusters (BGCs) related to the production of secondary metabolites. A total of 519 BGCs from the genus Saccharopolyspora were used for analysis and terpenoid BGCs were found to be widespread and most abundant in this genus. In addition, there are abundant novel BGCs in the genus Saccharopolyspora, which are not clustered with the known BGCs in the database, indicating that the metabolites of the genus Saccharopolyspora deserve further exploration.
