Justification | An eastern Overberg endemic (EOO < 5000 km²), known from five locations. Declining as a result of alien plant invasion, and habitat loss to crop cultivation. Over 70% of its habitat has been lost in the past 80 years to wheat cultivation. The generation length of this species is unknown. |

Provincial distribution | Western Cape |
Range | Caledon to Albertinia. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Breede Shale Renosterveld, Eastern Ruens Shale Renosterveld, Central Ruens Shale Renosterveld, Ruens Silcrete Renosterveld, Greyton Shale Fynbos, Breede Shale Fynbos, Swellendam Silcrete Fynbos, Cape Lowland Alluvial Vegetation |
