Description of Bogoriellaceae fam. nov., Dermacoccaceae fam. nov., Rarobacteraceae fam. nov. and Sanguibacteraceae fam. nov. and emendation of some families of the suborder Micrococcineae.

The hierarchic taxonomic framework described recently for the phylogenetic structure of the suborder Micrococcineae, class Actinobacteria, on the basis of 16S rDNA sequences and signature nucleotides was modified and extended. With the recent addition of novel taxa into the suborder, the phylogenetic coherence of some families was disrupted, leading to the emergence of novel lineages that, as judged by the depth of their branching points, were equivalent to those of described families. Bogoriellaceae fam. nov., Dermacoccaceae fam. nov., Rarobacteraceae fam. nov. and Sanguibacteraceae fam. nov. are proposed for these lineages. As a consequence of the restructuring process, some families have had to be emended, i.e. Dermatophilaceae, Cellulomonadaceae and Intrasporangiaceae.
