The members of this genus have variously been named under
Eperythrozoon,
Haemobartonella (before that,
Bartonella), and
Mycoplasma. When they were under
Mycoplasma, most species had a specific epithet starting with
hemo or
haemo (meaning "blood"), giving them the informal name "hemoplasmas" or "hemotrophic mycoplasmas". The merge into
Mycoplasma is now known to be misguided and resulted in a polyphyletic
Mycoplasma. The current circumscription of the genus is by Gupta et al. (2018). This article nevertheless uses these names because they imply a monophyletic
Mycoplasma. For more background on resistance to renaming medically-important bacteria, see . Species include: • "

Mycoplasma despite the 2018 change. == Clinical relevance ==
