Subspecies
Forms a superspecies with Yellow-breasted Barbet (Trachyphonus margaritatus), with which sometimes thought conspecific. Both rather closely related to D'Arnaud's Barbet (Trachyphonus darnaudii), less so to Crested Barbet (Trachyphonus vaillantii).
Proposed subspecies gallarum (south-central Ethiopia) and jacksoni (southern Ethiopia to north-central Kenya) probably represent intergrades of subspecies shelleyi and versicolor.
The following 3 subspecies are recognised:
shelleyi Hartlaub, 1886 - South-eastern Ethiopia to north-western and southern Somalia.
versicolor Hartlaub, 1882 - North-eastern Uganda and south-eastern Sudan to southern and central-eastern Ethiopia and northern Kenya.
erythrocephalus Cabanis, 1878 - Central Kenya to north-eastern and north-central Tanzania.
