First Report of Mud Shrimp Austinogebia wuhsienweni (Crustacea: Decapoda: Upogebiidae) from Korean Waters

Abstract

Specimens of Austinogebia wuhsienweni (Yu, 1931) previously recorded from China to Japan were collected at a manila clam farm of 0.5 m depth in Hongseong, Yellow Sea. They were briefly described and illustrations included color photographs, since this was the first record of this rare species from Korean waters. Three species of Upogebiidae are known from Korean waters: Upogebia major (De Haan, 1839), U. issaeffi (Balss, 1913), and A. wuhsienweni (Yu, 1931). They are similar to each other, however, the presence of the ventral spines of the rostrum, a proximal knob on the lateral margin of the uropodal endopod, and a longitudinal carina on the inner surface of the palm of the male first pereiopod can easily distinguish the present species from the two species of Upogebia.
