Justification
This is a localized species to the Western Cape Province, South Africa, with all known subpopulations occurring within an area of 0.017 km². Based on the IUCN guidelines this species has an extent of occurrence (EOO) and an area of occupancy (AOO) of 4 km². It is known from a single location where ongoing decline is inferred to be taking place due to the recent surge in illegal harvesting of rare Conophytums taking place across the Western and Northern Cape. This species therefore qualifies as Critically Endangered under criterion B.

Description
Exposed, west-facing sandstone slopes.
Threats
Plants occur on land that is used for livestock grazing. Habitat degradation as well as trampling is a potential threat. It is a rare and localized species and is increasingly popular in cultivation and in demand by collectors. Illegal collection is highly likely to have taken place given the recent rapid increase in demand for Conophytums coming from China, Japan and Korea and the significant increase in illegal poaching events taking place across the Northern Cape since March 2019.
Population

This species is localized to a single ridge where it is locally abundant, with the population consisting of more than 1000 individuals. Population decline is inferred due to illegal collecting.
