  • Desulfotomaculum guttoideum is the correct name if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Desulfotomaculum.
  • Desulfotomaculum guttoideum, which shows high levels of relatedness to a cluster of Clostridium, should be excluded from the genus Desulfotomaculum. However, the authors do not propose nomenclatural change. Publication: Stackebrandt E, Sproer C, Rainey FA, Burghardt J, Pauker O, Hippe H.
