Justification of Red List category
This species has a moderately small range within which it occurs in a number of strictly protected areas. It is not believed to approach the thresholds for Vulnerable under the range size criterion (extent of occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend is unknown, but reported threats to the species would not indicate that there is likely to be an ongoing continuing decline despite the species restricted habitat requirements. Consequently it is not believed to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified and research into the true population size is needed. However it is believed that the population considerably exceeds the thresholds for listing as Vulnerable under the small population criteria, and as it is now known that the species is fairly widespread in the high altitude reserves of the Sichuan arc, the largest subpopulation is likely to exceed thresholds for listing as Vulnerable should there be evidence for a continuing decline. Consequently the species is evaluated as Least Concern.
