Taxonomy: Muscicapa Banyumas Horsfield, 1821, Province of Banyumas, Java.
Probably forms a superspecies with C. lemprieri, and has been considered conspecific; songs rather similar, and separation based mainly on plumage. Some evidence of hybridization with C. tickelliae in Malay Peninsula. Recently suggested that race magnirostris merits treatment as a separate species on basis of bill size, colour of male upperparts and long primary projection; further study required. Eight subspecies recognized.
