A bacterial strain, designated BT258ᵀ, was isolated from a soil sample collected from Uijeongbu-si, Gyeong-do Province, Republic of Korea. Cells were Gram stain negative, aerobic, rod shaped, motile by gliding, and formed light pink-pigmented colonies on agar plates. Growth of the isolate was observed at 10–37 °C and pH 6–7. A 16S rRNA gene sequence analysis revealed that strain BT258ᵀ is a member of the genus Adhaeribacter in the family Hymenobacteraceae and had the highest sequence similarity with ‘Adhaeribacter soli’ MA2ᵀ (97.1%), Adhaeribacter terreus DNG6ᵀ (96.6%), and Adhaeribacter terrae HY02ᵀ (96.5%). The predominant respiratory quinone of the isolate was MK-7, the main polar lipid was phosphatidylethanolamine, and the major fatty acids were C₁₅:₀ iso (37.7%), summed feature 4 (C₁₇:₁ anteiso B/iso-C₁₇:₁ I; 16.8%), and C₁₆:₀ (10.3%). The draft genome of strain BT258ᵀ had a whole length of 4,974,022 bp and DNA G + C content of 46.0 mol%. The digital DNA–DNA hybridization (dDDH) and average nucleotide identity (ANI) values between the novel isolate and ‘Adhaeribacter soli’ and seven other Adhaeribacter species ranged from 17.9 to 22.7% and 69.7 to 77.9%, respectively. On the basis of its phenotypic properties, genotypic distinctiveness, and chemotaxonomic features, strain BT258ᵀ represents a novel species in the genus Adhaeribacter, for which the name Adhaeribacter terrigena sp. nov. is proposed. The type strain is BT258ᵀ (= KCTC 72409 ᵀ = JCM 34303 ᵀ).
