Assessor(s)
J.H. Vlok, G.D. Duncan, D. Raimondo & H.M. Steyn
Justification
EOO 17 696 km², known from less than 20 locations. Declining due to ongoing habitat loss and degradation due to agricultural expansion, particularly overgrazing, in the Little Karoo, where more than 80% of the habitat is severely grazed.
Distribution
Endemism
South African endemic
Provincial distribution
Northern Cape, Western Cape
Range
Tanqua Karoo to Montagu, Barrydale and Calitzdorp.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Fynbos

Population
Population trend
Decreasing
Notes
Recent collections by H.M. Steyn in the Tanqua Karoo significantly extended the known range of this species, which was previously thought to be rare and localised.
