The taxonomic position of a soil isolate, strain 13.4(T), was established u
sing a polyphasic approach. The organism was found to have chemical and mor
phological properties consistent with its classification in the genus Amyco
latopsis. Phylogenetic analysis of the strain based on its 16S rDNA sequenc
e showed that it forms a distinct phyletic line within members of the genus
Amycolatopsis. The organism was also readily distinguished from the type s
trains of all validly described Amycolatopsis species by its phenotypic fea
tures. The name Amycolatopsis rubida sp. nov. is proposed for this new spec
ies. The type strain is strain 13.4(T) (= AS 4.1541(T) = JCM 10871(T)).
