Critically Endangered (CR)

Rationale

A range-restricted endemic species from the Western Cape Province in South Africa (EOO 2 km<sup>2</sup>, AOO 16 km<sup>2</sup>). The taxon is only known from two subpopulations close to one another on the mountain slopes above Greyton, which constitutes one location. The habitat is under constant threat from encroachment by alien vegetation and also disturbed by recreational activity as it is near to and on popular hiking trails. The taxon thus qualifies globally under the IUCN criteria as Critically Endangered under criterion B. Due to the incorrect information being used for the previous assessment, the number of locations was given as two instead of one. The two colonies are a short distance from each other and are thus one location. Accordingly, the previous assessment should have been based on one location too, making it Critically Endangered, thus the change in status from Endangered to Critically Endangered is non-genuine.

Distribution

Endemic to the Western Cape Province in South Africa, in the mountains near Greyton.

Population trend

Trend

There is no information currently available.

Threats

The area is threatened by invasive alien trees, including Pines and Hakea. The butterfly occurs along popular hiking trails where the presence of hikers may disturb the habitat.

Conservation

This taxon has not been seen at the colony closest to town for the last three years. This area had a fire less than five years ago. The two colonies need to be surveyed and monitored to see if the population closest to town recovers and to check how healthy the population furthest from town is.
