The deep-water mysid, Hansenomysis lucifugus (Faxon, 1893), previously known only from the type locality off the Galapagos Islands, is rediscovered off western Mexico. A complete description is provided based on this new material. The new records correspond to a series of 15 adult females and increase the known distribution of this species by over 30° of latitude to the north, to 30°51.26’N–116°42.18’W. Although no precise depth range in the water column is known for this species, it has been collected in localities where total depth was at least 1848 m.

New Material

Specimens of Petalophthalmus armiger Willemoes-Suhm, 1875, were collected off western Mexico during a deep-water survey. Six males and 32 females were obtained from 18 sampling localities in western Mexico. The species is redescribed in detail, including illustrations of body and appendages, and SEM photographs of the mandibles. The new material indicates that P. armiger is widely distributed in the area and more common than previously thought in the eastern Pacific. Samples indicate that P. armiger inhabits water far offshore, where total depth exceeds 1000 m. Due to the lack of discrete samplings in the water column, however, the precise depth interval where P. armiger occurs cannot be defined.

Based on two specimens collected in the Antarctic deep-sea (4928 m) the adult female and male of the genusPseudolamprops Gamô, 1989 are described for the first time. A new combination is proposed, Pseudolamprops profundus(Reyss, 1978) comb. nov., and several new records from the North Atlantic and Antarctica are provided. The diagnosis of Pseudolamprops is revised on the account of the new material available.

SynopsisFrom a faunistic survey in Scottish waters, concentrated mainly in the sea lochs of the north-west coast and in the deep water in the North Sea off the east coast, thirty-two species of polychætes are listed which have not previously been recorded from these areas. Seven of the species are new records for British coastal waters or for the North Sea.

The mysid fauna of the Rockall Trough consists of more than 35 species partitioned between the pelagic water column and the bentho-pelagic environment. The pelagic mysids are dominated by Eucopia grimaldii, E. unguiculata and Boreomysis microps. The benthopelagic mysids, in a transect from 400 to 2900 m depth, are divided into four faunal associations. Pseudomma affine dominates the 400–800 m depth range; the impinging bathypelagic Gnathophausia zoea and the benthopelagic Boreomysis widens dominate the 800–1300 m range;Michthyops parva and Paramblyops rostrata are co-dominants in the 1400–2300 m range; while Amblyopsoides ohlinii dominates the 2170–2965 m range. The benthopelagic mysid fauna is most diverse at depths below 1400 m. It is dominated by species whose geographical distribution is restricted to the North Atlantic, in contrast to the pelagic mysid fauna, which is dominated by cosmopolitan species. Notes on the breeding season, biology and population structure of several species are given.

In preparation for the near future deep-water exploitation in the Mexican oil industry, the Mexican Petroleum Institute and Pemex carried out the first oceanographic sub-surface mooring installation in deep waters, in Lankahuasa area in 1500 m water depth. The aim of this project is to supply the necessary water column information for planning, installation, development and production activities for the Mexican offshore industry. Parameters measured include, current velocities, current direction, internal waves as well as traditional water quality measurements. Profiles of conductivity, temperature and Depth (CTD) from 100 m up to 2,500 m water depths were obtained from cruises where samples were taken over a wide area during January and February 2005. Salinity and density are calculated from CTD data. Oceanographical parameters were measured by 3 ADCP (Acoustic Doppler Current Profile) and by 2 current meters in the entire water column. The oceanographic situation during the deployment was characterized by the presence of an anticyclonic (clockwise rotating) eddy and a cyclonic one in the area, located to the north of 21° N. Both eddies were slowly propagating in a general southward direction.

Abstract Three species of the deep-water genus Paralomis White, 1856, are reported from western Mexico, two of these for the first time: Paralomis aspera Faxon, 1893, previously known from Panama to Peru, and P. otsuae Wilson, 1990, previously known only from Chile. The third species, P. multispina (Benedict, 1895), has numerous records in the eastern Pacific, particularly off California. Information related to the habitat of each species is provided.

Gulf Of Tehuantepec

In the Tropical Eastern Pacific region, the gammaridean amphipods of the families Maeridae and Melitidae are represented by 28 species and 11 genera; the genus Elasmopus is the richest, with 13 species. The examination of approximately 3,250 specimens resulted in 12 new records from the Gulf of Tehuantepec, belonging to four genera, Elasmopus, Maera, Quadrimaera and Melita. All species are illustrated and described. Seven new species are described as: Elasmopus bastidai n. sp., Elasmopus karlae n. sp., Elasmopus lecroyae n. sp., Elasmopus marcelae n. sp., Elasmopus oaxaquensis n. sp., Maera umarae n. sp., and Melita bousfieldi n. sp. With these new species the genus Elasmopus from the Tropical Eastern Pacific is increased to 18 species that corroborates the hypothesis of Barnard (1979) “on the Pacific there are (sic) a mark of speciation of genus Elasmopus”. In addition, there are five new records from the Gulf of Tehuantepec: three species of Elasmopus and two of Quadrimaera. Also, the range distribution of Elasmopus temori Barnard and E. zoanthidea Barnard, is increased to the north from the Galapagos Islands to the Gulf of Tehuantepec; for E. tubar Barnard, Quadrimaera chinarra Barnard, and Q. reishi Barnard, there are new intermediate records between the Gulf of California and the Galapagos Islands. With the exception of the species of Quadrimaera, all known species represent the second record in the region after their first descriptions.
