The two Millisia strains have 16S rRNA signature nucleotides that are characteristic of members of the order corynebacteriales , but not characteristic of their closest phylogenetic neighbors in the family Gondoniaceae (Stackebrandt et al., 1997). The family gondoniaceae in not used in the present volume, and the phylogenetic analysis used for the roadmap places Millisia within the family Nocanliceae (Zhi et al., 2009 , Ludwig et al., 2012 – the roodmap to the volume)
