A new species of tanaid, Chauliopleona sinusa, is described on the basis of material from Shijiki Bay, Nagasaki, and Tomioka Bay, Kumamoto, southwestern Japan, including both male and female specimens. The female is distinguished from those of other species of the genus by the following combination of characters: pereonites with straight lateral margins; maxilliped basis without long setae; cheliped completely devoid of carpal shield; propodus and dactylus with strong dorsal crenulation; pereopod 1 with carpus bearing ventrodistal row of spines. The male may be separated from that of C. hansknechti Larsen and Shimomura, 2007, the only congener for which the male is known, by its pleonites without posterior protuberances, cheliped propodus and dactylus with strong dorsal crenulation, and carpus with a robust expansion and very weak shield.
