Justification
This species was last recorded in 1952, and not seen again despite dedicated searches and survey projects. It is possibly extinct, although the reasons for decline are not known. It may also be overlooked, and chances remain that it could still be found.
Distribution
Endemism
South African endemic
Provincial distribution
Northern Cape
Range
Bokkeveld Escarpment near Nieuwoudtville.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Hantam Karoo
Description
Rocky clay flats.
Threats
Unknown, possibly habitat loss to crop cultivation or overgrazing.
Population

This species is known from a single collection, made in 1952, and not recorded again at the type locality or anywhere else on the Bokkeveld Escarpment, despite several dedicated searches (N.A. Helme pers. comm. 2015), as well as survey projects to document the populations of rare and threatened species of the area. Intact habitat still remains, and it is not certain why the population disappeared, and it is possibly overlooked. It is very likely a highly localized species.
