The erythropini mysid, Pleurerythrops secundus Murano, 1970, is recorded in shallow waters of the northeastern coast of Izu-Ohshima Island, Pacific coast of central Japan. Underwater surveys at a depth of 15–30 m by a scuba diver revealed that P. secundus lived on the benthic hydroids Aglaophenia whiteleggei Bale, 1888, Dentitheca hertwigi (Stechow, 1909), Gymnangium hians (Busk, 1852), Plumularia habereri Stechow, 1909, and several unidentified hydroid species. This finding represents the first evidence of P. secundus associated with benthic organisms. Furthermore, to the best of our knowledge, this is the first report of a mysid species in association with hydrozoans.
