Reicheocactus is a monotypic genus of cactus in the family Cactaceae, native to north western Argentina.

[3] It was once thought to be a synonym of Rebutia,[6] and commonly found in cactus nurseries as Lobivia famatimensis.

[7] The genus name of Reicheocactus is in honour of Karl Friedrich Reiche (1860-1929), who was a German botanist who worked as a university professor in Chile and Mexico.

[8] The Latin specific epithet of famatimensis is derived from Sierra de Famatina, a mountain range and massif in the Andes of the Argentine province of La Rioja.

The potential development of mining in its natural habitat could affect the populations of the species in the near future.
