Systematics
Chaetodon mesoleucos was first formally described in 1775 by the Swedish-speaking Finnish explorer, orientalist, naturalist Peter Forsskål (1732-1763), his description was published in 1775 by his companion on his expedition to Yemen, the orientalist and mathematician Carsten Niebuhr. The type locality was given as Al-Mukhā in Yemen.[4] It belongs to the large subgenus Rabdophorus which might warrant recognition as a distinct genus.[5]
