Closely related to D. shorii. Until recently lumped with D. everetti, but differs from that taxon in heavily spotted and streaked vs virtually plain upper breast (2); stronger white postocular supercilium (2); (in female) glossy black crown and nape with bold white spotting vs matt-black crown with red nape (3); underparts scaled more than mottled (ns); central throat and chin white with black streaky mesial line vs lightly peppered black (ns); (in male) no reddish stain in black submoustachial area#R (ns). Recent molecular analyses provided “some support” for this split#R. Race malabaricum previously attributed to Whistler & Kinnear, but author is Whistler alone#R. Race raveni often synonymized with borneonense, which itself is sometimes considered inseparable from nominate. Six subspecies currently recognized.
