Summary:Nemipterus elaine n. sp. New English name: Elaine’s threadfin bream Figure 1, 2. Table 1. Holotype . SAIAB 81939, 140.8 mm SL, Indian Ocean, Mozambique Channel, RV Dr Fridtjof Nansen , bottom trawl, Station M 40, 25°12’48”S, 35°59’54”E, 116-120m, P.C. Heemstra & E. Heemstra, 8 October 2007. Paratypes . SAIAB 209565, 6: 121.8-147.8 mm SL, same data as holotype. [Tissue No. HM07-610, Genbank (COI) paragenetype: MT 468885; HM07-611, Genbank (COI) paragenetype: MT 468886]. Diagnosis . Pectoral-fin rays ii,14 (ii,13-15); gill rakers 14 (13-15); body moderately elongate, depth 3.0 (2.9- 3.2) in SL; head length about equal to body depth, depth 1.0 (1.0) in head length; diameter of eye about equal to or a little more than snout length, 1.0 (0.8-0.9) in snout; lower margin of eye tangent to a line from tip of snout to upper pectoral fin base; suborbital shallow, its lower edge emarginate, least depth 2.6 (2.4-2.6) in eye diameter; imaginary line extended upward from posterior edge of suborbital reaching dorsal profile about 5-6 scale rows before origin of dorsal fin; pectoral fins moderately long, reaching to about level of vent; pelvic fins very long, reaching to between level of vent and origin of anal fin; upper lobe of caudal fin produced into short filamentous extension. Description . Dorsal-fin rays X,9; anal-fin rays III,7; pectoral-fin rays ii,14 (ii,13-15); lateral-line scales 46 (46- 49); transverse scale rows 3½/8½; gill rakers 14 (13-15). Depth 3.0 (2.9-3.2) in SL; head 3.2 (3.0-3.2) in SL; head length about equal to body depth, depth 1.0 (1.0) in head; snout short, bluntly rounded in profile, 3.3 (3.3-3.6) in head; eye 3.1 (2.8-3.1) in head; eye moderately large, its diameter about equal to or a little more than snout length, 1.0 (0.8-0.9) in snout; lower margin of eye tangent to a line from tip of snout to upper pectoral fin base; interorbital width 1.2 (1.4-1.5) in eye; least depth of suborbital 2.6 (2.4-2.6) in eye; ventral margin of suborbital emarginate, its posterior edge more ...
