Rationale
The Dilated False Shieldback is Vulnerable under criterion D2 because it has a very small and restricted population. It is only known from the holotype and only from Mariepskop Forest in Mpumalanga Province, South Africa. Despite abundant surveys of the region, this species has not been encountered elsewhere, so its EOO and AOO are estimated at 4 km2. Due to its highly restricted distribution, even a small disturbance can have a detrimental effect on the survival of the species as a whole. The most likely threats to the species are deforestation, cultivation with plantation forestry or other agricultural crops or livestock grazing. Changes in microclimate or distribution of the species' food plants as a result of climate change are also a potential threat. Due to its small body size and low motility, this species cannot be expected to shift its range in response to changes in its habitat.
