Rationale (Changed due to Same category but change in criteria)
Known from only the type locality, and not recorded for more than 50 years. The existing evidence is that it is a valid species, and occurs in an area of high threat owing to radical habitat transformation by alluvial diamond mining, so it is listed as Critically Endangered (Possibly Extinct) under criteria B1ab(iii)+2ab(iii), notwithstanding that its cryptic and trap-shy nature may obscure a more common and widespread occurrence.
