See ¤ Solimonadaceae.
Sheu et al. 2011 propose to transfer the type species of the type genus of the family ¤ Sinobacteraceae in the genus ¤ Solimonas. According to Rule 37a, bacteriologists adhering to this proposal must change the name ¤ Sinobacter to ¤ Solimonas.
With the now defunct name Sinobacter there is now an inconsistency in the nomenclature with the name Sinobacteraceae. Therefore, Losey et al. 2013 propose the name ¤ Solimonadaceae fam. nov. to include members of the genera ¤ Solimonas and ¤ Fontimonas.
