A Gram-stain positive, yellow-coloured, aerobic, non-motile, catalase-positive and oxidase-negative, endophytic actinobacterium, designated strain EGI 6500705(T), was isolated from the surface-sterilized stem of a halophyte Anabasis elatior (C. A. Mey.) Schischk collected from Urumqi, Xinjiang province, north-west China. The organism had ornithine as the diagnostic cell-wall diamino acid. The major fatty acids were anteiso-C15:0, anteiso-C17:0 and iso-C16:0. The predominant menaquinones were MK-9, MK-10 and MK-11. The DNA G + C content of strain EGI 6500705(T) was 69.2 mol%. Phylogenetic analyses based on 16S rRNA gene sequence showed that strain EGI 6500705(T) is clearly affiliated with the genus Labedella and most closely related to Labedella gwakjiensis KCTC 19176(T), with 99.0 % sequence similarity. DNA-DNA relatedness between strain EGI 6500705(T) and L. gwakjiensis KCTC 19176(T) was 27.4 %. On the basis of phenophytic, chemotaxonomic and phylogenetic analysis, the strain EGI 6500705(T) represents a novel species of the genus Labedella, for which the name Labedella endophytica sp. nov. is proposed. The type strain is EGI 6500705(T) (=KCTC 29494(T) = CPCC 203961(T) = JCM 30092(T)).
