Distribution: Central Kalahari in Namibia and adjacent Northern Cape of South Africa.
Habitat: Vegetated red dunes. Onymacris multistriata lives in sand dunes where it can be seen running from grass tussock to grass tussock in search of food during the day, and take thermal refuge within grass tussocks.
