was discovered, with ca. 40-60 adult individuals, distributed over about 100 m2 in the type locality. This site is on the grounds of a temple, and some individuals grow close to the path for visitors and face a strong threat from human activities. Its status should therefore be of concern and addressed in further investigations.
</paragraph>
<paragraph pageId="0" pageNumber="85">We estimated the extent of occurrence of the species to be less than 100 km2. Over the last four years, we have observed a steady decline in the territory area of the habitat due to the temple building maintenance and road construction. Considering the present field information and IUCN categories of threat, this species should be included in the category Critically Endangered (CR B2ab(iii)).</paragraph>
