Hello,
a revision of the genus Epithelantha was made, with description of new taxa.

Donati, D., Zanovello, C., 2010: Epithelantha F.A.C. Weber ex Britton & Rose: nuovi dati su ontogenia, fertilità, simpatria e revisione del genere. Piante Grasse 30(4): 165-187

Here's the link where you can find the original article:

Interesting article.

Yes thanks for posting this link I found it very interesting. Particularly the sp. ilariae, never heard of it but it sounds nice. I'd love to get my hands on some seeds!
