A yellow-pigmented, non-motile, Gram-stain-negative, rod-shaped bacterium, designated II4T was obtained from soil sampled at Seongnam, Gyeonggi-do, Republic of Korea. Cells were strictly aerobic, grew optimally at 20-28 °C and hydrolysed casein. A phylogenetic analysis based on its 16S rRNA gene sequence revealed that strain II4T formed a lineage within the family Xanthomonadaceae and clustered as members of the genus Lysobacter. The closest members were Lysobacter terrae THG-A13T (97.88 % sequence similarity), Lysobacter niabensis GH34-4T (97.82 %), Lysobacter oryzae YC6269T (97.74%), Lysobacter yangpyeongensis GH19-3T (97.53 %) and Lysobacter enzymogenes ATCC 29487T (96.18 %). The principal respiratory quinone was Q-8 and the major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. The predominant cellular fatty acids were summed feature 9 (C16 : 0 10-methyl and/or iso-C17 : 1  ω9c) and iso-C15 : 0 and iso-C16 : 0. The DNA G+C content was 68.2 mol%. The average nucleotide identity and in silico DNA-DNA hybridization relatedness values between strain II4T and its closely related genus members with possible full genome sequences were ≤79.6 and 23.7 %, respectively. Based on genomic, chemotaxonomic, phenotypic and phylogenetic data, strain II4T represents novel species in the genus Lysobacter, for which the name Lyobacter terrestris sp. nov. is proposed. The type strain is II4T (=KACC 21196T=NBRC 113956T).
