Hemixus [sic] sumatranus
Mount Singgalang, western Sumatra.
Hitherto treated as conspecific with I. virescens, but differs in its white-streaked olive-brown vs clear whitish throat (2); long narrow pale streaks vs much more diffuse streaks on olive-brown vs paler, greener breast, and extending less far onto belly (3); dull olive-brown vs dull olive-green upperparts (2); more streaked and pointed feathers on crown (ns); less streaked ear-coverts (ns); and (based on relatively few recordings) no similarities between voices, such that comparisons of apparently homologous calls would result in scores totalling 5#R. Monotypic.
