Proposal of Nakamurella gen. nov. as a substitute for the bacterial genus Microsphaera Yoshimi et al. 1996 and Nakamurellaceae fam. nov. as a substitute for the illegitimate bacterial family Microsphaeraceae Rainey et al. 1997.

The bacterial genus Microsphaera Yoshimi et al. 1996 is illegitimate because of priority of the fungal genus Microsphaera (Wallr.) Lév. [Principle 2, Rule 51b(4) of the Bacteriological Code]. Therefore, a new genus name, Nakamurella, is proposed for the bacterial genus. The type species Microsphaera multipartita Yoshimi et al. 1996 becomes Nakamurella multipartita gen. nov., comb. nov. Due to the illegitimacy of the only genus in the family Microsphaeraceae Rainey et al. 1997, this family name is replaced by the new bacterial family name Nakamurellaceae.
