Systematics
The doublesash butterflyfish was first formally described in 1921 by the English ichthyologist Charles Tate Regan (1878-1943) with the type locality given as East London.[5] Regan honoured the collector of the type, the Natal fisheries officer Harold Walter Bell-Marley (1872-1945), in the specific name.[6] Its closest relative is the West African Chaetodon hoefleri.[4] Some authorities place this species within the nominate subgenus Chaetodon but others consider it to be incertae sedis.[6]
