The present study was carried out to clarify the taxonomic relationship between two closely related species, Li . 2002 and (ex Boyer 1973) Nielsen 1995. The maximum-likelihood tree based on the 16S rRNA gene sequence and the phylogenomic tree based on concatenation of 16 protein-marker genes showed that these species were similar. Average nucleotide identity (ANIm 99.25 %, ANIb 98.2 %) and digital DNA-DNA hybridization values (93.5 %) between DSM 13666 and DSM 497 were greater than the threshold values for bacterial species delineation, indicating that they belong to the same species. Therefore, Li 2002 should be reclassified as a later heterotypic synonym of (ex Boyer 1973) Nielsen 1995.

Both the genera and are members of the family . Their type species, both Sanger_33 and ASD5720, were isolated from human faeces. A comparison of their 16S rRNA gene sequences revealed 100% similarity, suggesting their close relatedness and the possibility of belonging to the same species.

Two mycelium-forming actinobacterial strains, designated as DLS-47 and DLS-62, were isolated from volcanic ash collected from the surface of a rock on the peak of Darangshi Oreum (a volcanic cone) in Jeju, Republic of Korea, and their taxonomic positions were investigated by a polyphasic approach. Both of the isolates showed growth at 20-42 °C, pH 6.0-9.

Four Gram-stain-negative, aerobic, rod-shaped bacteria, designated WL0002, WL0024, WL0050, and WL0075, were isolated from sediment in the coastal areas of Nantong City, China. Metagenomic analysis revealed higher relative abundance of taxa closely related to the four strains in sediment (0.79-2.
