Thirteen species belonging to five genera of pelagic amphipods of the family Lestrigonidae were collected during a deep-water survey off western Mexico: four species of Hyperietta, two species of Hyperioides, five species of Lestrigonus, and one species each of Phronimopsis and Themistella. This represents 93% of all known species of Lestrigonidae world-wide. A total of 1092 specimens were obtained in 40 sampling localities in the Gulf of California (35) and off southwestern Mexico (5). Although sampling methodology was rather heterogeneous, two species, Hyperioides sibaginis and Lestrigonus bengalensis, were particularly abundant (336 and 562 specimens) and frequent (present in 24 and 31 localities) in the samples, representing 82% of the total catch. The southernmost distribution limit of Hyperietta stebbingi is extended to off SW Mexico. Of the 13 species that were collected during this survey, 10 and 8 species co-occurred at two sampling localities in the SE Gulf of California.

Ten species belonging to the families Paraphronimidae and Vibiliidae were collected during a deep-water survey off western Mexico: two species of Paraphronima and eight species of Vibilia. This represents about 40% of all known species of these two genera world-wide. A total of 419 males and 607 females were obtained in 39 samples from localities in the Gulf of California (33) and off southwestern Mexico (6). Vibilia armata was by far the most frequently (32 localities) and most abundantly (687 specimens, 67% of the total) collected species, followed by V. longicarpus (231 specimens in nine localities) and P. crassipes (35 specimens in 9 localities). Co-ocurrence of species of Vibilioidea in our samples was very low, with maxima of seven and five species collected in the same sample, once each. Considering previous records, a total of 16 species of Vibilioidea (almost 70% of all known species) have now been reported from western Mexico: two species of Paraphronima and 14 species of Vibilia, including V. australis occasionally reported in the area as its junior synonym, V. wolterecki.

Bathybembix (bathybembix) bairdii, a deep water mollusc of the Family Trochidae, was collected in the Southeast Gulf of California, Mexico and off the coast of El Salvador during exploratory cruises depths of 778 m - 2140 m and was very abundant in El Salvador. Information on B. (b.) bairdii, distribution pattern from the Gulf of California indicate that this species is well adapted to severe hypoxic (

Water Species

A new species of deep waterEpimeriais described based on material collected in 1526–1586 m depth during the TALUD X expedition in the central Gulf of California, Mexico. It is the sixth species of this genus reported for the East Pacific.Epimeria morroneisp. nov. is morphologically similar toE. norfanziLörz, 2011 (New Zealand, 1268 m depth) andE. coraJ.L. Barnard, 1971 (off Oregon, USA, 2086 m depth).Epimeria morroneisp. nov., however, differs from these two species by a combination of several characters, including: vestigial eyes; multidentate mandibular lacinia mobilis; a distinct setae arrangement in palm and dactylus of gnathopods 1–2; the shape and relative size of coxae 1–5; and the shape of the telson.

Number Of Individuals

During deep-water (0–1550m) sampling operations off western Mexico performed between 1989 and 2014, a series of 89 specimens of pelagic amphipods of the family Eupronoidae was obtained, including two genera and four species: Eupronoe armata, E. maculata, E. minuta, and Parapronoe parva. The most abundant species (50% of total number of individuals) and frequently collected species (in 65% of samples with eupronoids) was E. maculata. Worldwide and regional distributions are provided for each species. Notes on previously used names are provided.

A New Species

Only a few previous surveys of the deep-water planktonic fauna have been accomplished off western Mexico, in particular in the Gulf of California. Samples of pelagic amphipods were obtained between surface and as deep as 2394 m using different gear during an extensive survey in this area. Among these samples, nine species of the genus Scina were recognized, including 78 specimens: 27 males and 51 females. The genus Scina inhabits mesopelagic waters at depths over 200 m, a community that remains largely unknown. The material examined includes a new species, the first reported from the Gulf of California, which is described and compared with its closest congeners, S. setigera Wagler, 1926 and S. parasetigera Zeidler, 1990. These three species share the presence of a long bristle on the base of the dactylus of pereopods 5 and 6. Scina sp. nov. differs from these other two species mainly by: 1) the shape and proportions of pereiopods 1–7; 2) the presence of three inner spiniform elements on uropod 1; 3) the insertion of the exopod on distal 1/3 of uropods. Of the remaining species collected during the survey S. borealis was by far the most abundant and widely distributed, followed by S. wolterecki and S. marginata. The other five species, S. curvidactyla, S. nana, S. pacifica, S. setigera, and S. submarginata, were represented by one or two specimens only. Co-occurence of species of Scina in samples was low with a maximum of four species in a single sample, all associated with S. borealis, the most common species. The distribution of Scina species collected during this survey is briefly discussed.

Abstract Two species of Euryplacidae were collected in western Mexico. Trizocarcinus dentatus (12 localities) and Euryplax polita (4 localities) were both found in the Gulf of California. In the case of E. polita 11 specimens (5 males, 5 females, one ovigerous female) were obtained, while in the case of T. dentatus 42 specimens (25 males, 10 females, 7 ovigerous females) were collected. The northern distribution limit of E. polita is extended to the northern Gulf of California (28°16′N 111°36′W). Environmental data for both species are provided, including depth range, temperature, dissolved oxygen, and sediment composition.

Four specimens of the sea cucumber Ypsilocucumis californiae Massin & Hendrickx, 2011 were obtained during sampling operations off western Mexico. These specimens permit identification of this species as a member of the deep-water holothuroid community off the west coast of the Baja California Peninsula. Previous records correspond to four locations (including the type locality) in the Gulf of California, where eight specimens were collected. SEM ossicles images are provided for the first time and new ecological data associated with the presence of this species are available: temperature, 5.34‒8.38 °C; dissolved oxygen, 0.15‒0.28 ml O2/l and salinity, 34.42‒34.51 ups. The specimens were present in a wide variety of sediments with an organic carbon content of 3.18‒5.20 mg C/g (5.47‒8.95 % organic matter). Density values indicated low abundance of this species in the area (2.63‒3.94 orgs/ha). Records presented here were in a depth range from 540 to 776 m, which corresponds to the lower limit of the Oxygen Minimum Zone of the eastern Pacific. Additional records are provided for the West Atlantic Ypsilocucumis asperrima (Théel, 1886) and a key to the species of Ypsilocucumis is provided.

Abstract. A very diverse ostracod fauna was discovered in the latest Permian strata of the Dongpan section, southwestern Guangxi, South China. Fifty-one species belonging to twenty-eight genera were identified and described, including two new species (Bairdia dongpanensis n. sp. and Spinomicrocheilinella anterocompressa n. sp). This type of assemblage, with nineteen palaeopsychrospheric species and four pelagic species, is the first world-wide deep-water ostracod fauna reported from the latest Permian strata and the first one recorded in the Permian of China. The palaeoenvironmental analysis allows one to propose an evaluation of the bathymetry variation along the Dongpan section.

Four species of squat lobsters were collected off the northwestern coast of the Baja California Peninsula, Mexico, during an exploratory survey of fishing resources. Janethogalathea californiensis, described from California was previously known from off the west coast of the Baja California Peninsula (two localities) and from the Gulf of California (three localities). Of the three species of Munida collected during the survey, M. tenella is recorded off the west coast of the Baja California Peninsula for the first time. These are the fourth record of M. hispida and the second record of M. quadrispina in western Mexico.
