Strain DBTF-15T grew optimally at 25–30 °C, at pH 7.0–8.0 and in the presence of 2.0 % (w/v) NaCl. The phylogenetic trees based on 16S rRNA gene sequences revealed that strain DBTF-15T joined the cluster comprising the type strains of species of the genus Palleronia . Strain DBTF-15T exhibited higher 16S rRNA gene sequence similarity values to the type strains (96.5–96.7 %) of Maribius pelagius and Maribius salinus than to those (94.6–96.1 %) of the three species of the genus Palleronia . It exhibited 16S rRNA gene sequence similarity values of less than 93.9 % to the type strains of the other recognized species. Strain DBTF-15T contained Q-10 as the predominant ubiquinone and C18 : 1 ω7c as the major fatty acid. The major polar lipids of strain DBTF-15T were phosphatidylcholine, phosphatidylglycerol and one unidentified aminolipid. The DNA G+C content of strain DBTF-15T was 68.7 mol%. The chemotaxonomic data and other differential phenotypic properties made it possible to distinguish strain DBTF-15T from the genera Maribius and Palleronia . On the basis of the data presented, strain DBTF-15T constitutes a novel genus and species within the class Alphaproteobacteria , for which the name Pseudomaribius aestuariivivens gen. nov., sp. nov. is proposed. The type strain is DBTF-15T (=KACC 19431T=NBRC 113039T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002677
