Seleniolycus pectoralis sp. nov. (Figs. 2, 3b, 4). Materials. Holotype: NMNZ P.40591, 380 mm SL, male, Pacific-Antarctic Ridge, north of Balleny and Scott Islands (64°40.0' to 64°42.3'S, 176°32.0' to 176°44.6'E), depth 1948-2594 m, longline, FV Avro Chieftain, Gerald Anderson, stn. OBS 1742/067, 27 March 2003. Paratypes: (n = 3): NMNZ P.40595 (2 specimens), 315 mm SL, male, and +350 mm SL (tip of tail missing), female, same data as for holotype; NMNZ P.42283, 380 mm SL, female, Pacific-Antarctic Ridge (63°39'S, 173°04'E), depth 2267 m, longline, FV San Aotea II, Simon Beatson, stn. OBS 1430/231R, 9 May 2001. Diagnosis. Differs from congeners by having ventralmost pectoral fin rays exserted, scales present on posterior 2/5 of body, dorsal fin rays 76-80, and anal fin rays 64-66. It is further diagnosed by the following combination of characters: suborbital head pores 6-7, preoperculomandibular pores 8; predorsal length 28.0-30.7% SL; snout length 28.3-36.6% HL, eye diameter 9.4-12.0% HL; pectoral fin rays 14-16; anterior dorsal fin pterygiophore associated with vertebra 6-7; vertebrae 23-27 + 61-63 = 86-89. Description. Principal counts and measurements are presented in Table 1. Vertebral centra symmetrical, with prezygapophyses and postzygapophyses of equal horizontal length. Anal fin pterygiophores 3 (3-4), inserted anterior to haemal spine of first caudal vertebra. Caudal fin with 1 epural, 4 upper and 5 lower hypural rays. Epipleural ribs on 3 (3-4) to penultimate precaudal vertebra. Gill rakers on outer surface of first gill arch simple (not furcate) and with spinules. Branchiostegal rays 6. Pectoral fin wedge-shaped; its origin below body midline; lower rays thickened, exserted. Pelvic fin absent. Body elongate; trunk relatively robust, tail laterally compressed. Head ovoid, robust; anterior profile of snout almost vertical. Eyes relatively large, circular, not reaching dorsal profile of head. Mouth subterminal; lower lips without lateral lobe, upper lip continuous across snout. Snout blunt, upper jaw ...
