Etymology: Sashatherina: Named after the first author's son Sasha, who has assisted his father frequently on collecting trips without any official acknowledgement so far of his being so helpful; gigantea: Named 'giganteus' to refer to the unusual size of this species as most Old World Atherinidae rarely
exceed 10 cm SL.
