1966 The Rebutiinae are a subtribe of cacti belonging to the subfamily Cactoideae, tribe Cereeae.

The medium to large flowers appearing on the side usually open at night.

The fleshy fruits are not bursting, scaly, thorned or glabrous.

The hilum and micropyle of the seeds are fused, an appendage is absent, and a mucous sheath is sometimes present.

In a 2010 classification of the tribe Cereeae, the subtribe Rebutiinae comprised seven or eight genera, depending on whether Aylostera was recognized as separate from Rebutia.
