Justification
Riama petrorum has been assessed as Endangered because its estimated extent of occurrence is 1,325 km2, all individuals are likely to be found in fewer than five locations, and there is a continuing decline in the quality of its habitat due to logging and the expansion of agriculture. Conservation measures should be taken to reduce the rate of habitat loss.
