Diagnosis. A medium sized (<1 m maximum total length) species of Centrophorus  with the following combination of characters: body relatively slender; head moderately long (20.5–25.1% TL); snout relatively short (horizontal preorbital length 6.4–8.4% TL) and rounded in dorsal view; first dorsal extremely long based (base length 20.8–23.3% TL, soft fin length 16.9–20.2% TL) and relatively high (height 5.7–7.2% TL), inner margin relatively short (5.3–6.8% TL, 2.6–3.2 in soft fin length); second dorsal fin much smaller in area to first, similar in height to first dorsal fin (height 1.0– 1.3 in first dorsal-fin height); pectoral fins large (anterior margin length 11.0– 13.0% TL), free rear tip elongate in larger individuals (2.2–4.0% TL); lateral trunk denticles of larger individuals sessile (not raised on pedicels), block-like, not elevated; upper teeth of larger individuals with erect to slightly oblique cusps; lower teeth of all sized specimens much larger than upper teeth, strongly oblique, blade-like; total vertebral centra 112–122; teeth 38–43/29–31.

Teeth strongly differentiated in upper and lower jaws, with upper teeth much smaller than lower teeth. Upper teeth of adults (based on CSIRO  About CSIRO H 7990-02) moderately large, with erect cusps, becoming slightly oblique posteriorly towards mouth corners, bases slightly overlapping ( Fig. 13aView FIGURE 13). Lower teeth much larger than uppers, cusps very strongly oblique, blade-like, overlapping, edges with fine serrations ( Fig. 13bView FIGURE 13).

Dermal denticles on flank below first dorsal fin varying greatly in shape between juveniles and adults; absent from insertions of fins and most of the dorsal surface of claspers. Denticles of a juvenile (408 mm TL) small, upright, slender, unicuspid, closely spaced (slightly overlapping), and posteriorly curved; about 0.4 mm long ( Fig. 14aView FIGURE 14).

Second dorsal fin moderately large, much smaller in area compared to first dorsal fin, relatively short; second dorsal-fin length 2.69 (2.66; 2.25–2.84) times its height; anterior margin slightly convex; apex narrowly rounded; posterior margin weakly concave, sloping strongly posteroventrally from apex; free rear tip relatively short, thick basally, inner margin length 2.09 (2.05; 1.83–2.40) in soft-fin length, 0.78 (0.81; 0.63–0.83) times fin height; spine length 0.42 (0.32–0.50 in paratypes> 700 mm TL) in height of fin; base of exposed fin spine level with mid pelvicfin inner margin, exposed just above level of junction with spine and soft portion of fin; exposed fin spine relatively long, robust, broad based, tapering distally.

Pelvic fins large, length 11.6 (11.4; 11.0–12.4)% TL, 1.20 (1.14; 1.18–1.44) times second dorsal-fin soft length; anterior margin slightly convex; apex narrowly rounded; posterior margin slightly concave; free rear tip acutely pointed, inner margin very slightly convex. Claspers of adult males relatively short, slender; tapering to a fleshy, narrowly rounded tip ( Fig. 15View FIGURE 15); outer length 2.9 (2.5–3.3)% TL, 3.16 (2.98–3.81) times its base length (n = 8); clasper glans about 0.3 in clasper inner length; apopyle and hypopyle connected by long clasper groove; rhipidion moderately large, laterally expanded, extended from hypopyle to anterior of clasper tip; lateral edge with a slender, straight spine; dermal denticles mostly absent from dorsal surface.

Meristic data. Total vertebral centra 118 (112–122), monospondylous precaudal centra 59 (56–62), diplospondylous precaudal centra 28 (25–29), total precaudal centra 87 (83–91) and diplospondylous caudal centra 31 (26–34). Tooth count (n = 5): 20 (19–22) + (21) 19–21 / 15 (15) + 14 (15–16); total 41 (38–43)/29 (30–31).

Colour. When fresh: Dorsal and lateral surfaces brownish, sometimes with a reddish hue (grey in some specimens, particularly smaller specimens); ventral surfaces paler (only slightly paler in paratype CSIRO  About CSIRO H 7990- 02); waterline between dorsal and ventral colour shades diffuse and poorly defined on body, more distinct on head and caudal peduncle. Fins without markings in larger specimens; tip of free tip of first dorsal fin often paler; nearterm embryo with blackish dorsal and caudal fins and black anterior margins to paired fins, with narrow white posterior margin to dorsal and paired fins. Similar colour in preservation; fin markings of embryo less distinct.

Size. Postnatal type specimens ranged from 408 to 905 mm TL; a 637 mm TL male was immature; males adult between 719 and 776 mm TL; an 890 mm TL female was pregnant with a 346 mm TL late-term embryo (both paratypes). White & Dharmadi (2010) recorded: females up to 930 mm TL; an 873 mm TL pregnant female with a single 45 mm TL early-term embryo; males adult between 679 and 775 mm TL, while a 657 mm TL male was immature. Compagno et al. (2005) reported on a 737 mm TL immature male.

Distribution. Type material from off Taiwan (Cheng-gong and Da-xi fish landing sites—local fishing grounds), Indonesia (off southwest Java and eastern Lombok), and Papua New Guinea (Huon Gulf) ( Fig. 10View FIGURE 10). Compagno et al. (2005) reported this species off Puerto Princesa City in the Philippines ( JPAG 226, tissue accession GN4348); differed slightly in ND2 sequence and specimen not examined in this study. Limited depth information available as most specimens collected from fish landing sites; caught from depths of 330–460 m in Papua New Guinea (P. Neira, pers. comm.).

Etymology. Specific name a combination of the Latin longus (long) and pinna (fin) in allusion to the very distinctive long-based first dorsal fin this species possesses.

Holotype Paratypes Paratypes

(<524 mm TL) (> 644 mm TL) ......continued on the next page ......continued on the next page The Maximum Likelihood tree generated from the ND2 sequences obtained provide further support for the separation of C. lesliei  and C. longipinnis  as valid species ( Fig. 16View FIGURE 16). Centrophorus lesliei  samples form a distinct group nested within, but separate from, the three long-snout species groups (i.e. isodon-tesselatus-westraliensis, harrissoni  , and isodon-tesselatus). The long-snout species group requires further attention and will be dealt with in a subsequent part of this revision series for this genus. It should be noted that none of the sequenced specimens from Madagascar are type species as whole specimens were not retained, however, they were obtained from the Mozambique Channel, close to the locality of the holotype and three paratypes of C. lesliei  . Centrophorus longipinnis  forms a distinct group well separated from the long-snout and C. lesliei  groups. Within the C. longipinnis  group, two samples (GN 11175 from Indonesia and GN 4348 from the Philippines) show some differences to the main group ( Fig. 16View FIGURE 16). But morphologically, the Indonesian specimen is identical to the other C. longipinnis  specimens and is considered to be this species.

Moura et al. (2015) concluded that the BMNH specimen was C. uyato  based on DNAAbout DNA sequence comparisons for CO1. This result is inconsistent with the findings we present herein. Morphological data suggest that the BMNH specimen is C. lesliei  and furthermore, is very distinct from C. uyato  in possessing a much longer first dorsal-fin base. Munoz-Chapuli & Ramos (1989) recorded vastly different first dorsal-fin ray counts between C. lusitanicus  (= C. lesliei  ) and C. granulosus  (= C. uyato  ), i.e. 7–9 vs. 16–19, reflecting the large difference in length of the first dorsal fin. Thus, it is not conceivable that these two species could be considered conspecific, or that the BMNH specimen is a long finned variant of C. uyato  . Moura et al. (2015) state in their acknowledgements that they obtained a tissue sample from the BMNH specimen and also from ‘the Aquário Vasco da Gama Museum, and Aldina Inácio  …’ and state at the end of the sentence state, in parentheses, that ‘ DNAAbout DNA extraction was unsuccessful’. One possibility is that the BMNH specimen was the one which DNAAbout DNA extraction was not successful on and that a sample from the other source(s) was C. uyato  . A tissue sample from the BMNH specimen was also collected as part of a broader Chondrichthyan Tree of Life project led by one of us (GN) but despite numerous attempts, no valid DNAAbout DNA sequence could be obtained.
