Cells of strain PG2S01T were Gram-negative, strictly aerobic, non-motile, non-fermentative, orange-pigmented, moderately halophilic rods. Growth was observed in the presence of 0.25–7.5 % NaCl and at 10–40 °C. The dominant fatty acids were iso-C15 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), iso-C17 : 0 3-OH, iso-C16 : 0 3-OH, iso-C15 : 1 G and iso-C15 : 0 3-OH. The major polar lipids were phosphatidylethanolamine and several unidentified aminolipids, phospholipids and other lipids. The G+C content of the chromosomal DNA was 44.6 mol%. 16S rRNA gene sequence comparison showed that strain PG2S01T was most closely related to Owenweeksia hongkongensis UST20020801T (88.9 % 16S rRNA gene sequence similarity); levels of similarity between strain PG2S01T and the type strains of recognized representatives of genera in the family Cryomorphaceae were <88 %. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain PG2S01T formed a distinct evolutionary lineage within the family Cryomorphaceae . Strain PG2S01T was distinguishable from members of phylogenetically related genera by differences in several phenotypic properties. On the basis of phenotypic data and phylogenetic inference, strain PG2S01T represents a novel species in a new genus in the family Cryomorphaceae , for which the name Phaeocystidibacter luteus gen. nov., sp. nov. is proposed. The type strain of the type species is PG2S01T ( = CCTCC AB 209288T  = LMG 25704T  = MCCC 1F01079T). An emended description of O. hongkongensis Lau et al. 2005 is also proposed. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.030254-0
