and are each genetically homogeneous species, as indicated by the high levels of DNA homology (≥76%) exhibited by strains of these taxa. However, the results of a numerical analysis of total soluble cell protein patterns and biochemical test data revealed that there are two phenotypic subgroups within and two phenotypic subgroups within . The overall randomly amplified polymorphic DNA (RAPD)-PCR band patterns obtained for the majority of strains corresponded well to the pattern obtained for the type strain of (strain DSM 20019). However, six strains of had different, but similar, RAPD-PCR profiles and grouped in a separate genetic cluster, which was linked to one of the clusters of strains. On the basis of these results, differences in biochemical and physiological characteristics, and total soluble cell protein profiles, we describe the subspecies subsp. subsp. nov. and subsp. subsp. nov. for Abo-Elnaga and Kandler 1965 (Klein et al. 1996, emended description). Strains of grouped in two RAPD-PCR clusters, which was consistent with previous reports of phenotypic heterogeneity. Strains of , including type strain LMG 9844, clustered with the type strain of (strain NCFB 2714), indicating that these organisms belong to the same genetic group. We propose that strains of Katagiri, Kitahara, and Fukami 1934 (Klein et al. 1996, emended description) should be reclassified as members of subsp. subsp. nov. and subsp. subsp. nov. Strains of are reclassified as members of subsp. , and the name Stetter and Stetter 1980 is rejected.
