This recently described species is only known from two collections in Sichuan province, China. Further surveys are needed in the region to better understand its status. Due to the apparent lack of significant threats a rating of Least Concern is given. However, the present known range is restricted and the onset of any threatening process may warrant a re-assessment to a threatened category.
