Subspecies
No subspecies.
Black-capped Speirops (Zosterops lugubris) and Mount Cameroon Speirops (Zosterops melanocephalus) (Sibley and Monroe 1990, 1993) are retained as species contra Dowsett and Forbes-Watson (1993) who include melanocephalus as a subpecies of Black-capped Speirops (Zosterops lugubris).
Forms a superspecies with Mount Cameroon Speirops (Zosterops melanocephalus), and formerly considered conspecific, but morphologically and ecologically different. Principe Speirops (Zosterops leucophaeus) possibly belongs to same superspecies.
