Aylostera yuncharasensis (Rausch) Mosti & Papini


This species was originally found by Walter Rausch at Yunchara Railway Station, which is around 40km west of Padcaya in Bolivia, but was initially not identified or described other than “sensu Digitorebutia”. Regarded by many as a form of Aylostera atrovirens, it was found to be distinct enough to be given specific status by Mosti & Papini (2011).

The original description is here.
