Dibrachichthys is from the Greek di, meaning 'two', brachion meaning 'arm' and ichthys meaning 'fish', in reference to the undivided pectoral fins. The specific name melanurus is from the Greek melanos, meaning black, and oura meaning 'tail', in reference to the black bar across the caudal-fin base.
