Widespread across the Indo-West Pacific: Madagascar, Tanzania, Papua New Guinea, Indonesia, Malaysia, the Philippines and Japan. The type locality is East Africa / Zanzibar.

Etymology

The specific epithet albus (feminine alba) is the Latin for "white" and refers to the predominantly white body colour.

Originally described as Pleuroleura alba Eliot, 1904 in "On some nudibranchs from East Africa and Zanzibar, part V" (Proc. Zool. Soc. Lond.). Pleuroleura is now treated as a synonym of Dermatobranchus.
