Justification | This species was last collected in 1960 on the eastern outskirts of Uitenhage. It is quite likely now locally extinct in this area due to habitat loss to urban and industrial development. Other similar habitat in the area has however not yet been thoroughly surveyed for remaining subpopulations, and therefore this species can not yet be classified as Extinct. |
