New Records for Physetocaris Microphthalma Chace (Decapoda, Caridea, Physetocarididae) From the South Pacific

Abstract

Between July 1962 and December 1972, as part of the U.S. Antarctic Research Program, the USNS Eltanin was involved in a systematic, multidisciplinary survey of the Antarctic, Subantarctic, and adjacent regions of the Pacific and Atlantic oceans south of 30°S. Extensive use of a 3-m Isaacs-Kidd midwater trawl formed an integral part of the biological portions of this program. Numerous samples of midwater organisms were collected and subsequently processed by the Smithsonian Oceanographic Sorting Center. Among the pelagic caridean crustaceans provided me by the Smithsonian Oceanographic Sorting Center for a report on the Oplophoridae collected from the South Pacific were two specimens of Physetocaris microphthalma Chace, taken at positions which considerably extend the geographical range of this rare species.
