Paraliparis posteroporus n. sp. Figs. 67, 68 Holotype. NMNZ P.043692, male, 240 mm TL, 219 mm SL, 71°55.80' S, 173°18.08' E, NW edge of Mawson Bank, R / V Tangaroa, Stn. IPY / CAML TAN 0802 /144, 23 February 2008, 1431– 1658 m, NMNZ P.043692/1, cleared and stained right pectoral girdle. Diagnosis. V 69, D 60, A 54, P 20, notch rays long, some rudimentary. Mandibular pores set well back from symphysis and edges of lower jaw, chin pore pair not in a pit, close together, posterior to symphyseal knob of lower jaw. Teeth almost entirely uniserial except near symphysis. Pectoral fin lower lobe much longer than upper lobe. Radials 4, round, R2 and R3 notched opposite to each other, other radials unnotched. Scapular helve absent, coracoid with deep basal notch. Description. Counts V 69 (13+56), D 60, A 54, C 6?, P 20 (13+3+4), radials 4 (1+1+1+1), pc ≥6, pore formula unknown. Ratios.

In % HL: HW 74.9, sn 23.4, E 22.1, orbit 30.9, io <30.6, uj 38.2, go 11.6, bd ~116, preD 159.8, preA 223.9, sna 76.6, aAf 135.2, UPL 66.3, LPL 89.3, pabd 155.5, cp 4.3, pcl 35.9. Head less than 1/5 SL, low and compressed, dorsal profile rising evenly from snout through flat interorbital region. Snout short, low, bluntly rounded, projecting slightly beyond upper jaw. Anterior ends of suborbital stays projecting as a prominent strong knob on each side, probably more obvious as a result of damaged snout. Nostrils damaged, apparently close to anterior margin of orbit. Mouth horizontal, subterminal; lower jaw slightly included, oral cleft reaching below anterior half of orbit. Teeth simple, sharp, evenly spaced canines, arranged uniserially for most of jaw length. About 30 premaxillary teeth in a single row, gradually smaller anteriorly before some irregularly bi- or tri- serial teeth near symphysis. Symphyseal gaps present in both jaws; in upper jaw, wide, with a clear notch anteriorly; in ...
