Etymology: Siphamia: A Swazi word, siphama, for a fish; brevilux: The species is named brevilux (Latin: “short-light”) with reference to the length of its light organ,
which is the shortest for the genus and an essential character for separating this species from its nearest relatives (Ref. 90035).
