Justification of Red List category
This species is among the most poorly known in Asia. First, there is considerable uncertainty over whether its status as a species is valid, with alternative suggestions in the literature that it is either (1) a morph of another species; or (2) a hybrid. These hypotheses remain to be tested. Second, the species is known from only two specimens (one from Sumatra in 1900, one from Borneo in 1937) and observations made in Brunei in 1992. While this suggests it to have a Sundaic distribution, the paucity of sightings since, in a relatively well-explored part of Asia, makes determining its range (and the likely threats within it) impossible. For these reasons, it is classified as Data Deficient.
