Assessment rationale/justification
The EOO is estimated at around 900 km<sup>2</sup>, which falls within the threshold for threatened categories. However, there is little information on threats to this species, making it difficult to estimate the number of locations or ascertain whether it is experiencing a continuing decline. As a result, this species is assessed as Near Threatened (B1a+2a; D1) due to its restricted distribution and the probability that the population size is small. No regional adjustment is made.
