Rationale

This species is endemic to the southern Africa region where it has a wide range and is locally abundant. No population declines are known or expected and the species is assessed as Least Concern, globally. In South Africa, it has only been recorded once in 1963 in the southern Kruger National Park. Despite many searches in recent years it has not been recollected. As this area has suffered great climatic fluctuations in recent years, both flood and drought events, could have affected both larva and adult life phases of this species. Since South Africa can be recolonized from elsewhere if favorable conditions should return, surveys are encouraged to inform the reassessment of the species at the national level. The species is currently assessed as Regionally Extinct.
