Lycenchelys aratrirostris Andriashev and Permitin, 1968 Lycenchelys aratrirostris Andriashev and Permitin, 1968: 615, figs. 24 (type locality: off South Shetland Islands); Anderson, 1988: 89, figs. 30-31; Anderson, 1990b: 259, fig. 3. Material examined. South Shetland Islands: SAM 34599 (1 specimen, 202 mm SL), off Elephant Island, 61°12.6'S, 54°32.3'W, 559 m, POLARSTERN sta. AGT 15, Agassiz trawl, 19 Nov. 1996, K.-H. Kock. SAM 34534 (5, 176-220 mm SL), off King George Island, 62°18.9'S, 58°41.7'W, 491-497 m, POLARSTERN sta. AGT 175, Agassiz trawl, 24 Dec. 1996, K.-H. Kock. SAIAB (RUSI) 53455 (4; 199-264 mm SL), off Smith Island, 700 m, POLAR DUKE, otter trawl, 5 July 1996, A. DeVries. Diagnosis. Lycenchelys aratrirostris is distinguished from its congeners by the following combination of characters: fleshy mandibular symphysis deep, its length 18-20 % HL; suborbital pores 6-7; vertebrae 22-24 + 77-86 = 100-110. Description. Vertebrae 22-24 + 77-81 = 100-104; D 951-00; A 80-82; P 14-16; C 10-12; pelvics 3; branchiostegal rays 6; gill rakers 2 + 9-10; vomerine teeth 0-11; palatine teeth 0-11; pseudobranch filaments 0-7; pyloric caeca 2. Following proportions as percent SL (specimens 176-220 mm SL first followed by 264 mm SL male in parentheses): head length 16.4-17.2 (20.7); head width 7.5-8.2 (11.1); head depth 7.3-7.8 (9.8); predorsal length 18.2-20.0 (24.0); preanal length 34.5-36.7 (41.6); pectoral base depth 4.7-7.0 (4.2); pectoral-fin length 5.6-8.7 (10.5); body depth 7.8-8.6 (9.3); gill slit length 4.9-5.9 (4.6). Following proportions as percent HL, data presented as above: head width 44.2-47.8 (52.7); head depth 42.6-47.8 (47.3); mandibular symphysis length 15.4-20.7 (19.8); upper jaw length 39.5-43.2 (46.4); snout length 21.0-25.4 (26.8); eye diameter 18.1-25.6 (17.2); gill slit length 28.3-34.5 (22.1); pectoral-fin length 47.3-50.7 (50.7); interorbital width 6.7-8.4 (6.9); interpupillary width 26.4-27.8 (21.4); caudal-fin length 14.6-19.4 (12.7); pelvic-fin length 7.6-12.0 (6.7).
