An ovigerous female specimen of Nerocila phaio- pleura Bleeker, 1857 was collected from a bottom trawl catch in offshore waters of the East China Sea on 28 July 1994 during a research cruise onboard the Mie University’s training vessel Seisui-maru. This repre- sents the first record of N. phaiopleura from the East China Sea. While the specimen was found on the man- tle of a Japanese common squid, Todarodes pacificus Steenstrup, 1880 (Cephalopoda: Ommastrephidae), it most probably transferred from an unknown fish host to the squid in the trawl net during fishing operation or net retrieval.
