Conclusion
In conclusion, it’s our opinion that the genus Epithelantha needs a taxonomical revision. We adopt the following one.

Dedication
Epithelantha ilariae is dedicated to Ilaria MONTANARI, a young child suffering a very serious illness,
and to all the suffering children. We hope in this way that the fighting for life of this little
plant in its hard environment will testify that, whatever occurs, Life remains the strongest forever.

На мене лично по ми допада тая класификация, отколкото допускането, че всички тия таксони, едва ли не, са разновидности на Epithelantha micromeris. Авторите превеждат детайлни описания, много данни за ареала на разпространение, факти, че не са намерени промеждутъчни форми и хибриди, данни за цъфтежа и опрашването.
