This new species is only known from two locations in Songkhla province. The estimated number of mature individuals might be more than 2,500 but less than 10,000. The Area of Occupancy (AOO) is about 2,000 km2. Although its type locality and overall distribution are located within conservation areas, the species is still threatened by human disturbance. Therefore, we provisionally assess its conservation status to be "Vulnerable (VU), B2 b(ii) c(ii)", following the criteria of the
