== Discovery == This genus and its only species were first described in 1964 by the American marine biologist Joel W. Hedgpeth and the British zoologist William G. Fry. They based the original description of this genus and this species on eight adult specimens (five females and three males). These specimens were collected in Antarctic waters at a depth of about 2,800 meters below the surface. The female holotype and male allotype are deposited in the National Museum of Natural History in Washington, D.C., and two paratypes are deposited in the Natural History Museum in London.
