Phylogenetic and biochemical analysis indicated that this bacterium represents the first species of a novel genus belonging to the family Hyphomicrobiaceae . The 16S rRNA gene of strain 42-50T shares 96.3–94.2, 96.3, 96.2 and 94.9–93.8 % sequence identities to those of species from the genera Devosia , Youhaiella , Paradevosia and Pelagibacterium , respectively. The major cellular fatty acids are C16 : 0, C18 : 0, C18 : 1 ω7c 11-methyl and summed feature 8 (comprising C18 : 1 ω7c and C18 : 1 ω6c). The predominant polar lipids are diphosphatidylglycerol, phosphatidylglycerol and two unidentified glycolipids. The predominant respiratory quinone is ubiquinone-10 (Q-10). The DNA G+C content of strain 42-50T is 73.7 mol%. The distinct phylogenetic lineage and unique cellular fatty acids suggest that strain 42-50T represents a novel species of a new genus affiliated with the family Hyphomicrobiaceae , for which the name Arsenicitalea aurantiaca gen. nov., sp. nov. is proposed. The type strain is 42-50T (=CCTCC AB 2014325T=KCTC 42825T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.001543
