Notes

This taxon has been cultivated rarely under the provisional name of T. longispinus. It was discovered in 1982 by Heinz Swobodae near the village of Cerritos and has been named after the Turbinicarpus enthusiast Paolino Panarotto.

In my view this taxon is a transitional form between T. schmiedickeanus ssp. klinkerianus fa. schwarzii and T. schmiedickeanus ssp. rioverdensis.
