Etymology: Akysis: Derived from Greek, a = without + Greek, kysthos = bladder (Ref. 45335); bilustris: The specific epithet is the Latin adjective bilustris, meaning "that lasts two lustra (i.e. ten years)", in reference to the fact that the specimens comprising the type series were collected in two expeditions exactly ten years apart (Ref. 87997).
