At present, only three small subpopulations with total ca. 300 mature individuals of the new species are known in the type locality, Jiulianshan National Natural Reserve, Jiangxi Province, China. The three subpopulations are stable because they are in the reserve. The known AOO and EOO of the new species are about 0.2 km2 and 25 m2, respectively. Thus, if considering its fewer individuals of three subpopulations, it should be temporarily assessed as Near Threated (NT), following the IUCN Red List Categories and Criteria (
