The assessment by Bahir et al. (2005) is followed here. Listed as Vulnerable because all individuals are found in a single locality, which is a tourist destination so there are threats of disturbance and pollution. It is not listed as Critically Endangered because there is no evidence that there is a decline in the extent and quality of its habitat; however the extent of occurrence is estimated at <5 km² as this species has a very restricted range.
