A novel actinomycete strain ET3-3ᵀ isolated from soil collected from Chachoengsao province, Thailand was taxonomic evaluated using a polyphasic approach. Chemotaxonomic analysis indicated that meso-diaminopimelic acid was the diagnostic diamino acid in the cell-wall peptidoglycan. Mycolic acids were present. Ribose, arabinose, and galactose were detected in its whole-cell hydrolysates. The strain comprised C₁₆:₀ and TBSA 10-methyl C₁₈:₀ as the main fatty acids and MK-8(H₄ω-cycl) as the predominant menaquinone. Major polar lipids were phosphatidylinositol, phosphatidylinositol mannoside, phosphatidylethanolamine, and diphosphatidylglycerol. The results of 16S rRNA gene sequence analysis showed that strain ET3-3ᵀ was closely related to Nocardia seriolae JCM 30082ᵀ (99.2%), Nocardia yunnanensis JCM 30082ᵀ (98.4%), and Nocardia concava JCM 12351ᵀ (98.2%). The draft genome of ET3-3ᵀ was 9.31 Mb with 8826 coding sequences with an average G + C content of 68.0%. The comparison of the draft genome of strain ET3-3ᵀ and N. seriolae NBRC 15557ᵀ showed the ANIb, ANIm and the digital DNA-DNA hybridization values of 86.3%, 88.5% and 32.9%, respectively. The results of the taxonomic analysis suggested that strain ET3-3ᵀ represented a novel species of the genus Nocardia for which the name Nocardia terrae sp. nov. is proposed. The type strain is ET3-3ᵀ (= JCM 33776ᵀ = TISTR 2837ᵀ).
