Population justification: The species is currently known from six sites, and may occur in more. Based on extrapolations from density estimates produced by fieldwork, the population is estimated to number 50-249 mature individuals. This equates to 75-374 individuals in total, rounded here to 70-400 individuals.

Trend justification: Although the species is known from only very few sites no specific threats have been identified and it is not thought to be declining at present, thus the population is suspected to be stable.
