Psednos steini Chernova 2001
No full textPsednos steini Chernova 2001 Because the specimen (USNM 200488, subsequently designated as the holotype) had disintegrated, Chernova (2001) described this species using Stein’s (1978) description of it as Psednos micrurus Barnard 1927. Unfortunately, Chernova did not have the original data taken from the specimen, nor was she aware of a radiograph of it. Comparison of her redescription with the original counts and measurements indicates that in some respects her description should be modified in accordance with these data. In particular: the nostril is not level with eye center, but rather above it; the retroarticular angle of the lower jaw is on a vertical anterior to the posterior margin of the eye, not under it; the lower pectoral lobe is longer than the upper, not shorter (UPL 55.5 % HL, 13.6 % SL; LPL 78.9 % HL, 19.3 % SL). The base of the lowermost pectoral fin ray is on a vertical at about half the postocular distance, rather than at 3/4. Vertebrae are 41 (10+31), neither unknown nor 43 as stated, and the specimen definitely had five caudal fin rays.Published as part of David L.

The social problem of men in Europe: The social problem and societal problematisation of men and masculinities: "The social problem of men" Policy Option Paper 1
No full textIn March 2000, the European Research Network on Men in Europe project entitled “The Social Problem and Societal Problematisation of Men and Masculinities” (HPSE-CT-1999-0008) was initiated. The project, planned for three years (2000–2003), is funded by the Research Directorate of the European Commission under its Framework 5 Programme.
The overall aim of the Research Network is to develop empirical, theoretical and policy outcomes on the gendering of men and masculinities. The Research Network has focused on two closely related gendered questions:
• first, the specific, gendered social problem of men and certain masculinities; and,
• second, the more general, gendered societal problematisation of men and certain masculinities.
This work is primarily contextualised in terms of welfare responses to social problems and inequalities. It also has direct relevance to policy outcomes in relation to changing family structures; and work configurations within the labour market, the home and wider European society

A. Lavrentyev ”, cruise 71, station 8–7, collector I. Eidus. Diagnosis. A species of Careproctus with the following combination of characters: vertebral column with a deep curve, vertebrae 46 (8+38). Pleural ribs absent. D 42 (including 5 precaudal), A 36, P about 24, C 8 (principal rays). Hypural plate unslitted. Pores 2-5-6-1. Head 24.4 % SL, preanal 34.9 % SL; pelvic disk 38 % lc. Pale pinkish when fresh, head and peritoneum black. Description. Fresh specimen (Fig. 8 C). Body pale, translucent. Head massive globular. Anterior part of head and belly black because of ink-black orobranchial cavity and peritoneum, tail pale pinkish. Preserved specimen. Anterior part of body globular, caudal part low and elongated. Head deep and wide (76 and 71 % lc). Snout short and abruptly blunt. Snout skin fold does not cover the upper jaw. Nostril at level of upper half of eye. Eye large (29 % lc). Mouth terminal, horizontal. Oral-cleft end under anterior margin of pupil. Chin massive, angular when viewed from below. Teeth simple, with small lateral shoulders, in a few regular oblique rows. In anterior part of jaws are 5 teeth in oblique rows. Gill slit reaching to the 3 rd pectoral-fin ray. Pore formula unusual: nasal 2, infraorbital 5, preoperculomandibular 6, suprabranchial 1. Radiograph. Vertebral column with a deep curve. Vertebrae 46 (precaudal 8, caudal 38). Pleural ribs absent. Dorsal-fin rays 42 (precaudal 5). Anal-fin rays 36, the first ray inserts behind the 2 nd haemal spine. Rayless pterygiophores absent; anteriormost dorsal-fin ray inserted between neural spines 3 and 4. Hypural plate unslitted. C 8 (4+4) principal. Dorsal and anal fins low. Pectoral fin notched; lower lobe rays elongated and filamentous at the ends. Pectoral fin includes about 24 rays (about 17 in upper lobe, 7 in lower lobe). Pelvic disk not large. Anus twice closer to disk than to anal-fin origin. Preserved specimen pale, disk uncolored. Peritoneum and orobranchial cavity black. Distribution. The type specimen was found on the Pacific side of the Bussol Strait at a depth of 2350–2358 m (in the same trawl as C. pulcher). Environmental conditions. Same as for C. pulcher. Etymology. The name is derived from the Latin word “globula”, as the anterior part of the body is almost spherical. Comparative note. Globular body and strongly curved vertebral column are among the main characters of the liparid genus Psednos Barnard (Chernova 2001; Andriashev 2003). However, Careproctus globulus differs from all Psednos species by the presence of the pelvic disk (absent in the latter) and by an un-transformed structure of the cephalic sensory system, as the disposition of pores is typical for Careproctus but not for Psednos (i.e., the coronal pore is absent; the upper nasal pore opens lower than the nostril). Additionally, the holotype of 43 mm SL is a juvenile, and Psednos includes dwarf species which are already adult at this length. Not a single species of Careproctus is known with the following combination of characters: vertebrae 46 (abdominal 8), principal caudal-fin rays 8, absence of pleural ribs, one suprabranchial pore, and strongly curved vertebral column. Careproctus globulus was found in the same trawl as C. pulcher, but undoubtedly, it is a new species. If compared with the juvenile C. pulcher, С. globulus differs from the latter by its spherical body and deep curve of vertebral column (Fig. 10 B), by the absence of pleural ribs, number of principal caudal-fin rays (8 vs. 10) and by its black peritoneum.Published as part of Chernova, Natalia, Thiel, Ralf & Eidus, Irina, 2020, Four new species of Careproctus (Cottoidei: Liparidae) from the deep-water vicinity of the southern Kuril Islands (Western North Pacific), pp. 71-87 in Zootaxa 4821 (1) on pages 84-85, DOI: 10.11646/zootaxa.4821.1.3, http://zenodo.org/record/439826

Cephalic pore pattern 2-6-7-1; the suprabranchial pore located above the very edge of gill opening; chin pores are not brought together. Radiograph. Vertebrae 55 (precaudal 10, caudal 45), Dorsal-fin rays 49 (precaudal 7), four anterior rays shorter and weaker than the subsequent ones. Anal-fin rays 43, anterior one behind the first haemal spine. Rayless pterygiophores one (Fig. 5), anteriormost dorsal-fin ray inserted between neural spines 4 and 5. Pleural ribs absent. Hypural one, unslitted. C 1+5/4+1; principal rays 9. Dorsal fin immersed in a dense cartilaginous-like tissue to about middle of SL, completely hidden. In the second half of body, tips of D and A rays protrude from fin membrane (but the rays are soft). Dorsal and anal fins relatively low; their height in anterior half of body less than a third of body height. Pectoral fin with a deep notch separating its lower lobe, consisting of elongated filiform rays. Upper pectoral-fin lobe short (11.3 % SL), not reaching to A-fin origin. Lower lobe slightly longer (13.3 % SL or 118 % of the upper-lobe length), slightly extending beyond anus. Three pectoral notch rays (41 % of the upper-lobe length) slightly spaced, P 26 (16+3+7) in both fins.

In alcohol, skin grayish-brown; head, abdomen and pectoral fins blackish. Disk light. Peritoneum black, oral cavity gray. Blackish bands along bases of dorsal and anal fins not enter the narrowed posterior part of tail. Distribution. Kuril basin of the Sea of Okhotsk, depth 3301 m. Environmental conditions. Bottom sediments in the box-corer sample at the place of capture included the upper layer of thin brown silt, and deeper dense greenish silt. The ground from the Agassiz trawl included gray and brown silt. The bycatch was dominated by the holothurians Molpadia sp., Echiura and glass sponges; polychaetes were numerous (not less than 12 species including Travisia sp.). Gorgonians and alcionarians, as well as ascidia of Culeolus sp. and colonies of bryozoans Kinetoskias were few. Etymology. The name of the species is derived from the Latin words “brevis” (short) and “pectus” (chest, pectoral), since pectoral fins of this species are short compared with other species. Comparative notes. Absence of pleural ribs, pore number 2-6-7-1, deep and compressed leaf-like body (greatest depth 119 % of lc, depth above A-fin origin 113 %lc), short head (18 % SL) and short pectoral fin (11.3 % SL), cartilaginous-like tissue surrounding the dorsal fin and dense tissue around anus, distinguish the species from other Careproctus of the North Pacific, including the C. laperousi described above. By the number of vertebrae and fin rays, absence of ribs and by the pore formula, C. brevipectoralis is most similar to C. hyaleius Geistdoerfer which was described from deep-sea hydrothermal vents (Eastern Pacific, 12°48.63’ N, 103°56.41’ W, depth 2630 m) and possess similar counts (vertebrae 54–56, D 48–49, A 43) (Geistdoerfer 1994; Chernova & Geistdoerfer 2003). The new species differs from the latter by shape of body, black peritoneum (light in the latter), and pigmented skin (vs. the whole body is translucent). Other North Pacific Careproctus with number of vertebrae 52–61 (C. rotundifrons Sakurai & Shinohara, C. comus Orr & Maslenikov, C. boversianus Gilbert & Burke, C. batialis, C. marginatus Kido) differ from C. brevipectoralis in having 2 or 3 pairs of pleural ribs, three-lobed teeth and pore pattern 2-6-7-2. The state of pleural ribs is unknown for C. sinensis Gilbert & Burke, C. zachirus, C. longifilis and C. melanuroides, all having D 51–54, number of vertebrae 55–58 (unknown for C. melanuroides) and pores 2-6-7-1 (unknown for C. melanuroides). Careproctus sinensis and C. zachirus differ from C. brevipectoralis in having trilobed or shouldered teeth, larger head (25.7–27.7 % SL) and pale peritoneum. Careproctus longifilis and C. melanuroides posess black peritoneum but differ from C. brevipectoralis in having larger head (22.2–26.3 % SL vs. 18 % SL) and smaller disk (16.1–22.2 and 24.5–25.6 % lc vs. 41.5 % lc).Published as part of Chernova, Natalia, Thiel, Ralf & Eidus, Irina, 2020, Four new species of Careproctus (Cottoidei: Liparidae) from the deep-water vicinity of the southern Kuril Islands (Western North Pacific), pp. 71-87 in Zootaxa 4821 (1) on pages 77-79, DOI: 10.11646/zootaxa.4821.1.3, http://zenodo.org/record/439826
New and Rare Snailfishes (Liparidae, Scorpaeniformes) with the Description of Four New Species from the Southern Hemisphere and Tropical East Pacific 1
No full text1 Liparid fishes of the Southern ocean, Australia and other areas have been intensively studied (Andriashev, 1986; Stein and Tompkins, 1989; Andriashev and Stein, 1998; Stein et al., 2001; Andriashev, 2003). Knowledge of the diversity in the family has substantially increased, and more than 334 species of 29 genera are listed (Chernova et al., 2004). However, many of the species are known from a few or single specimens. For these reasons every new record of Liparidae is of inter-est. The present study concentrates on snailfishes found in the large ISH–ZMH collections of the Zoological Museum of Hamburg University, mainly from the Southern Hemisphere and from the adjacent tropical east Pacific. The focus was to identify unstudied mate-rials, to record new localities and data and to describe new species. All specimens found belong to 2 genera: Careproctus Krøyer 1862 which includes more than 105 species, and Paraliparis Collett 1879 containing not less than 112 species. Careproctus differs from Paraliparis mainly by having a sucking disk which is reduced in species of the latter genus. Representatives of both genera are widely distributed in the shelf, bathyal, and abyssal parts of the world's oceans. 1 The text was submitted by the author in English. MATERIAL AND METHODS Recent revisions (Andriashev, 1986; Stein and Andriashev, 1990; Chernova, 2001; Stein et al., 2001; Andriashev, 2003) were used for species identification. Methods traditionally used in liparid studies, including radiography and pectoral girdle preparation, were pre-viously described (Burke, 1930; Stein, 1978; Andria-hev, 1986; Kido, 1988; Andriashev and Stein, 1998; Chernova, 2001; Stein et al., 2001; Andriashev, 2003). Meristics were taken from radiographs using: D as number of rays for the dorsal fin, A as number of rays for the anal fin, P as number of rays for the pectoral fin, and C as number of rays for the caudal fin. Vertebrae numbers were obtained separately for abdominal and caudal vertebrae (urostyle included). The principal caudal-fin rays are those supported by hypural plates. Dorsal (ventral) procurrent rays, when present, are those shifted forward to the upper-posterior (lower-posterior) edge of the hypural plates (Kido, 1988). Teeth of liparids are arranged in oblique rows, with a similar number of rows on the right and left jaws. We counted the rows on half of each jaw (usually left), and also the number of teeth in full rows near the symphysis of the jaws. The diastema is a toothless interspace between tooth plates of the right and left jaws.Publishe
