Mt Singgalang [00°24’ S, 100°20’ E], western Sumatra

.

Hitherto treated as conspecific with L. argentauris, but differs in its dull coppery-red vs dull orange-yellow throat and breast in female (3); rich coppery-red vs strong ochre undertail-coverts in female (3); dull coppery-red vs orange-ochre hindcollar and upper mantle in both sexes (ns[1]); dull brownish vs pale yellowish-olive belly (2); more olive, less grey lower mantle, back and wing-coverts (ns[1]); longer wings and tail but not bill (effect size for male wing 2.0, score 2). Single available recording suggests only minor vocal difference#R; iris colour pale yellow in nominate but dark in race rookmakeri. Two subspecies recognized.
