Upper Kayan River, central Borneo.
Sometimes placed in Microtarsus. Owing to its extraordinary rarity (known from two specimens, each a taxonomic type, and some observations in Brunei), present species has been suggested to be a hybrid, since an enlarged and differently coloured eyering has previously been recorded in pycnonotid hybrids#R; however, while one parent would probably be Brachypodius atriceps, a plausible second parent is much harder to match against the characters produced#R. The possibility that the form is a rare morph is discounted because it does not appropriately fit any species#R. Thus, it seems better maintained as a species at least until genetic analysis illuminates its status#R. Two subspecies recognized.
