Justification of Red List category
This species is very poorly known. Following a review of available evidence (Berryman and Boakes 2023), the species is determined to be known from just eight specimens, collected in an eight-year window between February 1894 and April 1902 in the Bornean Central Highlands. These specimens are known from only three localities, one of which is imprecisely known. With more than 120 years since the last sighting, despite some moderate search effort, it is possible that this species is very rare. However, its sole congener is known to be highly elusive, and the area of potentially suitable habitat on Borneo is vast, poorly surveyed and often remote; it may consequently have a large population that is impervious to possible threats. Given the litany of uncertainties regarding this species' population size, trend and range, determining its relative extinction risk is currently not possible. Accordingly, it is listed as Data Deficient.
