Two soil isolates, strains 80-60T and 3.24T, were shown to have chemical and morphological properties consistent with their classification in the genus Actinomadura. The almost complete 16S rDNA sequences generated for the two organisms were aligned with available sequences of representatives of the genus Actinomadura and related taxa. It was apparent from the resultant phylogenetic trees that each of the strains formed a distinct phyletic line within the evolutionary radiation occupied by the genus Actinomadura. The two organisms could also be distinguished from one another and from representatives of all the validly described species of Actinomadura using a set of phenotypic properties. It is proposed that strains 3.24T (=AS 4.1522T =IFO 16341T) and 80-60T (=AS 4.1202T =IFO 14668T =JCM 16161T) be classified in the genus Actinomadura as Actinomadura catellatispora sp. nov. and Actinomadura glauciflava sp. nov., respectively.
