Abstract: A new species of Quinquelaophonte Wells, Hicks and Coull, 1982 from Port Phillip Bay, is separated from its cogeners by the presence of five elongate setae on P1 exopod-2. The P1 exopod-2 of all other species of Quinquelaophonte has two long setae and three shorter spines. In addition, the P1 endopod-2 of the new species has an accessory seta that is longer than the terminal claw. This condition is also present in Q. wellsi, the only other species of Quinquelaophonte described from Australia. The new species brings the total number of species of Quinquelaophonte to ten.
