The species is only known from a single holotype from 1866 although there have been more recent potential sightings, including one in 2017. Even so, their habitat is being lost to excessive logging of the forest on the island and there would be very few if any individuals left.
Although the species has been observed only once, in 1866, there have been reports of possible sightings since 2017. However, their natural habitat is being severely impacted by deforestation for logging purposes on the island, and it's likely that very few individuals remain.
