The status of two mesophilic filamentous actinomycetes isolated from an arid Australian soil sample was determined using a polyphasic taxonomic approach. The isolates had chemical and morphological properties consistent with their classification in the genus , assignments that were supported by analysis of 16S rRNA gene sequence data. Isolate SF26(T) formed a distinct phyletic line and hence was sharply separated from its nearest phylogenetic neighbour, DSM 44468(T). In contrast, isolate SF27(T) formed a subclade in the tree with DSM 44592(T) but was separated readily from the latter by DNA:DNA pairing data. The two isolates were distinguished from one another and from their respective nearest phylogenetic neighbours using a range of phenotypic properties. These data indicate that the two isolates should be recognized as new species in the genus . The names proposed for these new taxa are sp. nov. and sp. nov. with isolates SF26(T) (=NCIMB 14706(T) = NRRL B-2846(T)) and SF27(T) (=NCIMB 14707(T) = NRRL B-24847(T)) as the respective type strains.
