Justification:
This species is assessed as Vulnerable (VU) under criterion D2 because it has a very small area of occupancy (the extent of occurrence is only 10 km²) and it is only known from three locations. If there was any evidence of decline, the species would qualify as Endangered under criterion B1+2. Based on the lower population size estimate , the species comes very close to qualifying for listing as VU under criterion D1.
