Summary: | Gadomus longifilis (Goode & Bean, 1885) Fig. 3. Bathygadus longifilis Goode & Bean, 1885: 599. Albatross station 2392, 28° 47 ' 30 "N, 87 ° 27 '00"W, 1,324 m. depth. Syntypes:?SU 9546 (1), USNM 37338 (2). Type catalog: Böhlke 1953: 56. Parr, 1946: 8–17 (description, key); Iwamoto, 1970: 327– 352 (description, key); Marshall & Iwamoto, 1973: 518–530 (description, key); Howes & Crimmen, 1990: 192–201 (description, key). Material examined . MHNUSC 25005 - 1, 278 mm TL, 6 th August 2011, Galicia Bank; 42 º 40.390 ’N— 11 º 31.670 ’W; 1,450 m depth; MHNUSC 25005 - 2, 291 mm TL, 6 th August 2011, Galicia Bank; 42 º 40.390 ’N— 11 º 31.670 ’W; 1,450 m depth; MHNUSC 25005 - 3, 295 mm TL, 7 th August 2011, Galicia Bank; 42 º 58.51 ’N— 11 º 59.23 ’W; 1,683 m depth. Description. Body elongated and attenuated to the caudal peduncle; head small, 6.7–7.7 times in total length; snout blunt, 3.7–4.4 times into head; interorbital width about equal to horizontal diameter of orbit; long chin barbel present, strongly developed and 1.9–2.4 in head length; dorsal, pectoral and ventral fins with a single elongated ray, elongated second dorsal ray 1.8–2.4, elongated second pectoral ray 2.0– 2.3 and elongated first pelvic ray 2.0– 2.2 in the head length. The main morphometric and meristic characteristics are presented in Table 4. Habitat and distribution. Benthopelagic in tropical and subtropical North Atlantic between 520 and 2,165 m depth (Geistdoerfer, 1990). Amphi-Atlantic distribution; in western Atlantic it occurs in West Greenland (a single specimen), off east coast of Florida, Straits of Florida, Gulf of Mexico and Caribbean sea and in eastern Atlantic from the northwest of Spain (Galicia), Portugal, Azores, Canary Islands, Morocco, Mauritania and Gulf of Guinea (Marshall & Iwamoto, 1973; Maul, 1976; Geistdoefer, 1990; Jørgensen, 1996; Bañón et al . 2010; Sobrino et al . 2012). Gadomus arcuatus (Goode & Bean, 1886) Fig. 4. Bathygadus arcuatus Goode & Bean, 1886: 158. Off Martinique Island, West Indies, Blake station 205, 611 m. depth. Holotype: MCZ 28007. Parr, 1946: 8–17 (description, key); Marshall & Iwamoto, 1973: 518–530 (description, key); Howes & Crimmen 1990: 192–201 (description, key). Material examined. MHNUSC 25006 - 1, 566 mm TL, 13 th May 2011, Avilés Canyon; 43 º 57.850 ’N— 6 º 28.050 ’W; 1,450 m depth. Description. Body elongated and attenuated to the caudal peduncle; upper profile to first dorsal fin strongly inclined, with a pronounced hump-backed appearance; head moderately large, 6.2 times in total length; snout 4.8 times into head; interorbital width about equal to horizontal eye diameter and 5.4 times into head length; chin barbel present and of moderate size, 0.7 in head length; mouth large and terminal jaws beyond the posterior margin of the orbit; only one pelvic ray elongated but broken is patent, all rest of elongated rays are presumably broken, elongated first pelvic rays 1.3 and elongated first pectoral rays 1.3 in the head length. The main morphometric and meristic characteristics are presented in Table 5. Habitat and Distribution. Benthopelagic in tropical and subtropical Atlantic at depths between 610 and 1,631 m (Iwamoto, 1990; Sobrino et al . 2012). Amphi-Atlantic distribution; in western Atlantic from Nova Scotia (Canada), Gulf of Mexico, Caribbean, Surinam, French Guyana, north-eastern coast of South America and Brazil and in eastern Atlantic from Morocco, Azores, Canary Islands, Mauritania, Guinea-Bissau and Gabon (Marshall & Iwamoto, 1973; Iwamoto, 1990; Geistdoerfer, 1990; Howes & Crimmen, 1990; Melo & Menezes, 2002; Melo et al . 2010; Halliday et al . 2012; Sobrino et al . 2012). : Published as part of Bañón, Rafael, Arronte, Juan Carlos, Barros-García, David, Vázquez-Dorado, Sandra & Carlos, Alejandro De, 2013, Taxonomic study of Bathygadidae fishes (Gadiformes) from Atlantic Spanish waters combining morphological and molecular approaches, pp. 552-566 in Zootaxa 3746 (4) on pages 558-560, DOI: 10.11646/zootaxa.3746.4.3, http://zenodo.org/record/222237 |
