LAMPOCTES CRUENTIVENTER GEN. NOV., SP. NOV.: A NEW MESOPELAGIC LOBATE CTENOPHORE, REPRESENTING THE TYPE OF A NEW FAMILY (CLASS TENTACULATA, ORDER LOBATA, FAMILY LAMPOCTENIDAE, FAM. NOV.)

摘要

This paper describes a new genus and species of mesopelagic ctenophore in the Order Lobata, Lampocteis cruentiventer, which was first collected in 1979 off southern Califor- nia and later collected and studied in detail from 1991 to 1999 in Monterey Bay. This ctenophore differs from all previously described lobate ctenophores in two major ways: (1) all of the meridional canals have blind aboral endings, and (2) the body is penetrated by a deep notch located between the adjacent subtentacular comb rows at the level of the infundibulum.
