“Tartaria Chinensi”; error = Sumatra.
Supposedly extinct form bipunctatus, possibly from Tioman I (off Peninsular Malaysia) or perhaps from Java, known only from a portion of a single male primary of uncertain origin, has been considered a race of present species or, alternatively, a distinct species; the most recent analysis of the feather’s structure and pattern suggests that it is merely anomalous (representative of abnormal growth), and the feather should not therefore be taken as evidence for existence (or former existence) of an additional taxon of Argusianus#R. Races rather well differentiated. Two subspecies recognized.
