A yellow-pigmented, Gram-negative, aerobic bacterial strain comprising rod-shaped cells devoid of flagellar and gliding motility, designated strain A31, was isolated from a veined rapa whelk () collected from the South Sea, Republic of Korea. Results from 16S rRNA gene sequence analysis indicated that the isolate belonged to the family ; the highest level of nucleotide sequence similarity (92.6 %) was observed with KCTC 12569. The predominant cellular fatty acids were iso-C G (24.2 %), iso-C (20.1 %) and iso-C 3-OH (11.2 %). Flexirubin-type pigments were absent. The major isoprenoid quinone was MK-6. The DNA GC content was 31.7 mol%. Data from a polyphasic taxonomic study suggested that the isolate represents a novel species in a new genus of the family , for which the name gen. nov., sp. nov. is proposed. The type strain of is A31 (=KCTC 22186 =JCM 15075).
