The temperature, pH and NaCl ranges for growth were determined to be 15–35 °C (optimum, 28 °C), 6.0–8.0 (optimum, pH 7.0) and 0–2 % (w/v; optimum without NaCl), respectively. The polar lipdis detected for strain H14505T were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, glycolipid and four unidentified lipids. The predominant menaquinones of strain H14505T were MK-9(H4) and MK-9(H6), and the prevalent fatty acids (>10 %) were C18 : 1 ω9c, C17 : 1 ω8c, summed feature 5 (anteiso-C18 : 0/ C18 : 2 ω6,9c) and C16 : 0. Phylogenetic analysis based on 16S rRNA gene and whole-genome sequences indicated that strain H14505T showed high similarity to Catellatospora vulcania NEAU-JM1T (99.0 %) and Catellatospora paridis NEAU-CL2T (99.0 %), and formed a monophyletic clade within the the genus Catellatospora in the phylogenetic trees. However, the average nucleotide indentity and DNA–DNA hybridization values between strain H14505T and closely related Catellatospora species showed that it belonged to a distinct species. Furthermore, the results of morphological, physiological and biochemical tests allowed further phenotypic differentiation of strain H14505T from its closest relatives. Thus, it is proposed that strain H14505T represents a novel species of the genus Catellatospora , for which the name Catellatospora sichuanensis sp. nov. is proposed. The type strain of Catellatospora sichuanensis is H14505T (=JCM 32394T=CICC 11042T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.004175
