Report on some pandalid shrimps from the East China Sea (Decapoda, Caridea)

The present paper reports 15 species of pandalid shrimp from the East China Sea, including an undescribed species of represented by a damaged, ovigerous female specimen. This sp. is closely similar to forms of the Plesionika rostricrescentis group. It can be distinguished readily from other members of the group by the greater number of ventral rostral teeth, which are set more closely, the low basal rostral crest, and the short stylocerite, which does not project beyond the end of the first segment of the antennular peduncle. Besides this sp., the following species are reported for the first time from the East China Sea: Heterocarpus woodmasoni Alcock, 1901, Pandalus gracilis Stimpson, 1860, orientalis Chace, 1985, reflexa Chace, 1985, sindoi (Rathbun, 1906), and unidens Bate, 1888.
