Sharpe and C. Chubb, 1906,
Sandakan, Sabah, north-eastern Borneo.
Sometimes placed in genus Tropicoperdix. Formerly treated as a subspecies of A. charltonii, but differs in its plain dirty white vs plain tawny-buff ear-coverts (2); absence of a distinct black upper necklace from the lower throat around below the ear-coverts (2); much darker, richer chestnut on upper breast with black vs greyish-brown lower breast feathers, more narrowly, evenly and distinctly barred with buff (3); belly with darker rufous and rufous-chestnut coloration (ns); and darker upperparts (ns). It differs from A. chloropus in its absence of buff-tan band around lower throat/upper breast (3); upper breast and neck-sides rich chestnut vs dingy grey-brown (3); lower breast more boldly barred (2); remaining underparts two shades darker (ns); and darker upperparts (ns). Differences from A. tonkinensis are indicated under that species. Monotypic.
