Roseivivax atlanticus (Li, Lai, Liu, Sun and Shao, 2015) is a later heterotypic synonym of Roseivivax marinus (Dai, Shi, Gao, Liu and Zhang, 2014)

description

The genomes of the type strains of Roseivivax atlanticus and Roseivivax marinus ( Rhodobacteraceae , Alphaproteobacteria ), were analysed to determine their respective Average Nucleotide Identity (ANI) and in silico DNA–DNA hybridization (DDH) values. These species were proposed and effectively published relatively closely in time (February and August 2014, respectively) and so not taking account of the other. The intergenomic relatedness between both type strains, 97.0–97.4 % ANI and 82.8 % in silico DDH, confirm that they represent members of the same genomic species. This conclusion is also supported at the phenotypic level. Since the name Roseovarius marinus was validly published earlier, R. atlanticus (Validation List 161, IJSEM 65, 1–4. 2015) should be considered a later heterotypic synonym of R. marinus (Dai, Shi, Gao, Liu and Zhang, 2014), in application of the priority rule.
