A white-coloured bacterium, SGM1-$15^T$, was isolated from a paddy soil sample from Suwon, Republic of Korea. The cells were strictly aerobic, Gram-negative and curved rod-shaped. A phylogenetic analysis based on 16S rRNA gene sequences revealed that strain SGM1-$15^T$ was closely related to Curvibacter delicatus LMG $4328^T$ (97.6% similarity) and Caenimonas koreensis $EMB320^T$ (97.5% similarity). The major respiratory quinone system was Q-8 and the predominant cellular fatty acids were $C_{16:0}$ (39.9%), summed feature 3 ($C_{16:1}$ ${omega}7c$ and/or iso-$C_{15:0}$ 2-OH; 24.3%) and $C_{17:0}$ cyclo (22.7%). The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The major polyamines were 2-hydroxypurescine, purescine and spermidine. The DNA G+C content was 68.7 mol%. On the basis of the phylogenetic, physiologicl and chemotaxonomic data, stain SGM1-$15^T$ represents a novel species of the genus Caenimonas, for which the name Caenimonas terrae sp. nov. is proposed. The type strain of Caenimonas terrae is SGM1-$15^T$ (=KACC $13365^T$ =NBRC $106341^T$).
