A Gram-positive, milk–white coloured, aerobic strain, YIM 48868^T, was isolated from the rhizosphere soil of Maytenus hookeri Loes in Xishuangbanna, China. 16S rRNA gene sequence similarity studies showed that strain YIM 48868^T was a member of the genus Actinopolymorpha, showing 96.8 % sequence similarity to Actinopolymorpha singaporensis IM 7744^T and 97.0 % similarity to Actinopolymorpha rutila YIM 45725^T. Chemotaxonomic data (peptidoglycan type I, LL-diaminopimelic acid; sugar pattern C, glucose, rhamnose and ribose; polar lipids PI, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol mannosides and phosphatidylinositol) were characteristic of the genus Actinopolymorpha. A phylogenetic tree based on 16S rRNA gene sequences showed that strain YIM 48868^T formed a distinct phylogenetic lineage within the genus Actinopolymorpha. Strain YIM 48868^T could be differentiated from recognized species by means of phenotypic properties and the predominant menaquinones [MK-9(H₆), MK-9(H₈), MK-10(H₆), MK-10(H₈)]. The DNA G+C content was 66.6 mol%. The DNA–DNA relatedness values between strain YIM 48868^T and the type strains of A. singaporensis and A. rutila were 48.7 % and 53.1 %, respectively. These data, in combination with phenotypic and chemotaxonomic data, demonstrate that strain YIM 48868^T represents a novel species in the genus Actinopolymorpha, for which the name Actinopolymorpha alba sp. nov. is proposed. The type strain is YIM 48868^T (=CCTCC AA 208030^T=DSM 45243^T).

The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain YIM 48868^T is EU706350.
