placed with S. frontalis and S. oenochlamys in a
separate genus, Oenositta. The three may form a superspecies

however, occurs together with S. frontalis in Vietnam,
overlapping in both range and altitude in NW Tonkin (Fan Si Pan
Range) and S Annam (Da Lat Plateau). Relationship with S.

Relationship with S. oenochlamys more problematic, but Hainan race chienfengensis of present species may form link between the two (both are yellow-billed, whereas S. frontalis has red bill). Population of this species recently found on Kon Tum Plateau-Lo Xo pass area of Vietnam and adjacent SE Laos (Xe Sap region, in Xe Kong Province) of unknown race; study required. Three subspecies currently recognized.
