Hitherto treated as conspecific with D. hirundinaceum and D. ignicolle, but differs from latter in characters given under that species. Differs from D. hirundinaceum in its pink vs red chin to mid-breast (2); extension of red coloration around ventral stripe vs confinement to above mid-breast (3); weaker black ventral stripe (ns); very narrow dingy-white vs broad white lower breast and belly around ventral stripe (2); olive (in nominate) or olive-tinged dark grey (in fulgidum) vs grey flanks (ns); much shorter wing (effect size −4.66 for keiense, −4.51 for fulgidum, but n=9 for latter; score 2). Races possibly represent two species, separable by plumage and also by voice#R; further study required. Two subspecies recognized.
