Abstract

Izuohshimaphryxus hoshinoi, a new genus and species of hemiarthrine bopyrid, is described on the basis of a single female specimen from the coastal waters of Izu-Ohshima Island, Sagami Sea, Pacific coast of central Japan. This bopyrid infests an anthozoan-associated shrimp, Ancylomenes speciosus (Okuno, 2004), attaching to the dorsal surface of the pleon. This new genus is most similar to Filophryxus Bruce, 1972 but is distinguished by a) the presence of pereopods on the concave side, b) number of lateral plates of the pleon, and c) absence of a pleotelson. This is the third identified species known to attach to the dorsal surface of the pleon of a caridean shrimp host.
