One New Species

At present, only 11 species of harpacticoid copepods have been described from the deep sea of the Gulf of California and the west coast of the Baja California Peninsula. These efforts had until recently been focused exclusively on the families Ameiridae Boeck, Argestidae Por, and Rhizothrichidae Por. Preliminary analyses revealed also an important contribution of the subfamily Stenheliinae Brady (Miraciidae Dana) to the overall species richness and diversity of deep-sea benthic copepods from the west coast of the Baja California Peninsula, and the central and southern Gulf of California. One new species of the genus Wellstenhelia Karanovic & Kim, 2014, We. euterpoides sp. nov., and one new genus and species, Wellstenvalia wellsi gen. et sp. nov., are herein described from sediment samples taken at eight sampling stations in the west coast of the Baja California Peninsula and in the central and southern Gulf of California. Wellstenhelia euterpoides sp. nov. seems to be closely related to We. euterpe Karanovic & Kim, 2014 with which it shares the reduced armature complement of the baseoendopod of the female fifth leg. The so far monotypic genus Wellstenvalia gen. nov. was found to be closely related to Muohuysia Özdikmen, 2009 and Wellstenhelia. Some comments on the relationships between the new genus proposed here and other stenheliin genera and species are provided as a contribution towards the monophyly of the subfamily.

Detailed investigation of the essentially complete uppermost Miocene through Lower Pleistocene sequence in Deep Sea Drilling Project (DSDP) Hole 603C, western North Atlantic, has revealed the presence of the new dinoflagellate cyst speciesLejeunecysta hatterasensis, Lejeunecysta interrupta, Corrudinium devernaliae, andPyxidinopsis vesiculata, as well as the acritarchsLeiosphaeridia rockhallensisHead new species andLeffingwellia costatanew genus and species. Independent magnetobiostratigraphic control of DSDP Hole 603C constrains the ranges of these new species.Lejeunecysta interruptan. sp. appears to range no higher than lowermost Pliocene at 5.2 Ma,Pyxidinopsis vesiculatan. sp. has a range top at about 4.5 Ma in the Lower Pliocene,Corrudinium devernaliaen. sp. has a well-defined range of 4.7–4.1 Ma within the Lower Pliocene, andLeiosphaeridia rockhallensisn. sp. has a similarly well-defined range of 4.4–3.9 Ma within the Lower Pliocene. The presence ofLeiosphaeridia rockhallensisn. sp. in the Ramsholt Member of the Coralline Crag Formation, eastern England, supports an Early Pliocene age for this member.

Abstract Plankto-benthic ostracods of the subfamily Bathyconchoeciinae constitute an extremely heterogeneous group of species, as well in body size, as well as in the shape and structure of carapace and limbs. At present, their fauna contains 35 known (described) species, belonging to four genera. Besides that, about 50 species with still open nomenclature were noted in the literature and have been found in material from our collections. A preliminary morphological analysis of the bathyconchoeciines allowed, in addition, to single out 13 species complexes (= putative genera). One of these genera is described herein as Bathyconchoecilla gen. nov., from the deep-sea zone of the Kurile-Kamchatka Trench. The new genus differs from other genera in this subfamily by the shape and sculpture of the carapace, the location of the left hook on the second antenna in the male, and the structure of the coxale and basale of the mandible and the endites of the maxilla.

Deep Sea Sediments

A new genus and species of Desmodoridae was found in deep-sea sediments of the Campos Basin. Although the cuticle annulation of the new species is similar to members of Desmodorinae, many morphological features are strong enough to classify it within the Spiriniinae. Spirodesma magdae nov. gen. nov. sp. is characterized mainly by the presence of a unique form of unispired amphids, with circular amphideal fovea, and a buccal cavity with three equal teeth, one dorsal and two ventrosublateral.

Steringovermes notacanthi, a new genus and species of fellodistomine digenean, is described from the deep-sea spiny eel Notacanthus bonaparte from below 1,000m depth in the north eastern Atlantic. It differs from other related genera in the unique combination of a V-shaped excretory vesicle, multilobate, mainly post-testicular ovary and extensive vitelline fields extending into both the foreand hindbody. In addition, the fellodistomine Olssonium turneri Bray & Gibson, 1980 is reported for the first time from a fish not of the genus Alepocephalus, namely the alepocephalid Narcetes stomias.

A New Species

Five species of Caprellidea (Amphipoda) occur on a benthic transect between Gay Head, Massachusetts and Bermuda. Three species, Caprella rinki Stephensen, Mayerella limicola Huntsman, and Proaeginina norvegica (Stephensen) are refigured and redescribed. A new species of Thorina and a new genus and species are described from bathyal and abyssal depths. All five species are arctic–boreal in affinities and may be expected to range south only to Cape Hatteras on the continental slope, but much farther south at abyssal depths.
