A. Tamaki, 8 Jul 1998 (NSMT-Cr 12529). Distribution . Japan , South Korea , China ; British Columbia , Canada to California , U.S.A. , and Gulf of California , Baja California Norte, Mexico . Hosts . Grynaminna tamakii Poore, 2000 , Nihonotrypaea harmondi (Bovier, 1901) , N . japonica (Ortmann, 1891) , N . petalura (Stimpson, 1860) , Neotrypaea californiensis (Dana, 1854) , N . gigas (Dana, 1852) ( type host), Upogebia major (De Haan, 1841) . Remarks . The records of this species from an upogebiid host (An et al . 2009) may seem questionable as I . cornuta is otherwise only known from callianassid hosts but the congener I . thoracica ( Montagu, 1808 ) has been reported to infest both callianassid and upogebiid hosts in the Mediterranean ( Markham 2001 ). However, there are no records of I . cornuta from the west coast of the United States on any upogebiid host. Many early records had the host cited as Callianassa longimana , a synonym of N . gigas . Although Campos et al . (2009) listed I . cornuta as a parasite of N . gigas (based on data from Richardson 1905 ) and “ Ione sp.” as a parasite of N . californiensis (based on data from Haig & Abbott 1980 ), they did not find infested hosts of either species from the Gulf of California . The Mexican specimens reported here therefore represent the first record of I . cornuta from the Gulf of California . The specimens from Grynaminna tamakii are the first bopyrids recorded from this host species. The inclusion of “Nobuhiro & Kyoko 2004” in the synonymy list for this species by An et al . (2009) is an error as these are the first names of the authors Saito and Kinoshita (2004) . The specimens studied by Wardiatno (2004) were never named or figured; they are likely either this species or Pseudione longicauda Shiino, 1937 , as these are the only species known from Nihonotrypaea japonica .
