Justification of Red List category
This species has been uplisted to Endangered as its population is suspected (based on multiple accounts of its increased rarity in recent years) to have fallen below 2,500 mature individuals, with no more than 250 mature individuals in any one subpopulation. Heavy and unsustainable trapping is the primary driver of declines.
1000-2499 mature individuals
