Taxonomy: Dasycephala syndactyla Swainson, 1837, Sierra Leone.
Proposal that present species forms a species pair with B. eximius undermined by recent molecular evidence, which suggests that it is sister-taxon to the rest of genus. Moreover, these data do not support the traditional subspecific treatment as listed below, but indicate a more complex situation; pending further study, however, it is considered better to adopt an orthodox approach. Racial affiliation of birds in Angola uncertain, provisionally included in woosnami. Otherwise, race nandensis (described from N Nandi Forest, in W Kenya), is only very slightly more yellow bel..

Taxonomy: Dasycephala syndactyla Swainson, 1837, Sierra Leone.
Proposal that present species forms a species pair with B. eximius undermined by recent molecular evidence, which suggests that it is sister-taxon to the rest of genus. Moreover, these data do not support the traditional subspecific treatment as listed below, but indicate a more complex situation; pending further study, however, it is considered better to adopt an orthodox approach. Racial affiliation of birds in Angola uncertain, provisionally included in woosnami. Otherwise, race nandensis (described from N Nandi Forest, in W Kenya), is only very slightly more yellow below than woosnami, and regarded as a synonym of latter; multicolor (SE Nigeria E to W DRCongo) is not satisfactorily distinguishable from nominate. Species name sometimes given as syndactyla, but genus is masculine. Two subspecies recognized.

Subspecies and Distribution:

  • syndactylus (Swainson, 1837) - Sierra Leone E to W DRCongo (Bangui, Lukolela, Tshuapa).
  • woosnami Ogilvie-Grant, 1907 - E DRCongo (Kasai, Lualaba, Upper Congo), S Sudan, Uganda, W Kenya, N Angola and extreme NW Zambia.
