• Notes:
  • He et al. (2020) assigned this genus to the class Acidimicrobiia Norris 2013. Publication: He YQ, Chen RW, Li C, Shi SB, Cui LQ, Long LJ, Tian XP. Actinomarinicola tropica gen. nov. sp. nov., a new marine actinobacterium of the family Iamiaceae, isolated from South China Sea sediment environments. Int J Syst Evol Microbiol 2020; 70:3852-3858.
  • This taxon name is occasionally misprinted in some sources as: "Microthix"; "Microthris"; "Microtrhix".
  • The e-mail address of the corresponding author given in the effective publication is not functional any more.
  • Pittman et al. (1991) suggested the abbreviation "MITX" for this genus name but this does not appear to be of practical relevance any longer. Publication: Pittman KF, Walczak CA, Lock CM. Codes and abbreviations for approved of effectively published names of genera of bacteria published from January 1980 to December 1990. Int J Syst Bacteriol 1991; 41:571-579.
  • "Candidatus Microthrix" Blackall et al. 1996 is a later homonym of a genus name with standing in the zoological (animal) nomenclature: Microthrix Ragonot, 1888. Principle 2 of the 2008 Code is not retroactive, so the name does not contravene the Code because of this homonymy. In the event that this genus became validly published, it would be illegitimate. "Candidatus Neomicrothrix" has been suggested. Publication: Oren A. "Candidatus list no. 0." A plea for linguistic accuracy – also for Candidatus taxa. Int J Syst Evol Microbiol 2017; 67:1085-1094.
