Body of moderate depth, moderately compressed laterally (fig. 7b), greatest depth at anal fin origin unknown (19.7– 29.3)% SL, tapering uniformly from second dorsal fin origin to shallow caudal peduncle; caudal peduncle short, 5.4 (5.2– 9.2)% SL, strongly compressed, depth subequal to orbital diameter. Distance between middle of anus and base of anal fin slightly less than suborbital depth. Body cavity extending to above origin of anal fin.
Head acute, of moderate size, length 23.3 (23.3–31.6)% SL, width unknown (14.9–19.8)% SL and depth unknown (11.0– 17.9)% SL; snout of moderate length 7.5 (6.5–9.6)% SL, not projecting in advance of upper jaw, rounded in dorsal view. Nostrils small, located about two-thirds to three-quarters of the way from snout tip to eye, distance from nostril to orbital margin about equal to or greater than diameter of combined nostrils; nostrils positioned above horizontal through centre of eye, both with low tubular rim; posterior opening about half size of anterior, separated from it by raised skin flap. Interorbital of moderate width, very slightly convex. Eye of moderate size, orbital diameter 20.8 (16.8–28.5)% HL, unknown (0.91–1.68) times in interorbital space, unknown (1.46–4.71) times suborbital distance, circular, upper edge of eye adjacent to dorsal margin of head in lateral view. Postorbital moderately long, 1.00 (0.52–1.21) times length of upper jaw. Mouth large, terminal, upper jaw terminating at vertical through posterior margin of eye. Jaw teeth caniniform, slightly curved, depressible, band of up to four or five irregular rows in upper jaw with distinct hiatus at symphysis; teeth in outer row more regularly arranged than in inner rows; band tapering near rear of jaw. Teeth of lower jaw similar in form to those of upper jaw; band of two or three rows with broader patch on either side of symphysis, tapering to single, widely spaced row posteriorly; rows almost contiguous across symphysis. Vomerine teeth absent. Opercular bones strong; upper extremity of gill opening at horizontal through middle of eye; gill membranes continuous across isthmus. Gill rakers on outer arch slender, moderately short, unknown (about 0.6–0.8) times length of opposing gill filaments near angle, unknown (19–22) times in head length, slightly denticulate. Chin barbel of moderate length, subconical 21.1 (16.5–25.3)% HL.
Very small cycloid scales covering all of head and body except for branchiostegal membranes, surface of maxilla and premaxilla, lower lip and distal parts of fins; thick mucus covering obscuring scales and pores in freshly preserved material. Most head pores tiny, following main cephalic sensory canals; row of slightly raised pores from nostrils to tip of snout and then posteriorly just above lower edge of suborbital; row of enlarged mandibular pores on underside of lower jaw. Lateral line comprising widely spaced pores on short tubes arising from narrow scale-less gap, anterior end curved upwards slightly, then gradually descending to lateral midline below posterior 25% of second dorsal fin, remaining on lateral midline posteriorly.
Membranes of first and second dorsal fins continuous at base; first dorsal originating distinctly behind vertical through pectoral fin base; anterior two-thirds of second dorsal of uniform height, 7th to 9th ray from posterior end of fin longest, its height about 1.4 times length of 2nd ray at anterior end of fin, last ten or so rays progressively shorter; rays of both dorsal fins mostly unbranched, only last 13 to 16 rays, apart from last one to three, branched. Fleshy, fine scale-covered basal sheath on third or more of first dorsal and anterior portion of second dorsal fins; fin rays interconnected by membranes to tips, sheath gradually decreasing slightly in coverage and thickness posteriorly, encompassing about half of second dorsal fin near its insertion; sheath extending onto body for anterior third of combined dorsal fin base, broadest anteriorly, narrowing posteriorly. Profile of anal fin like that of second dorsal fin, although less deep posteriorly, with comparable unbranched and branched rays. Likewise, anal fin enclosed in broad fleshy sheath that is like that of dorsal fins; sheath also extending onto body for anterior third or less of fin. Caudal fin distinctly rounded without obvious dorsoposterior and ventroposterior corners in adults; all but anterior-most rays of similar length; base of fin covered by indistinct sheath with much smaller scales (sheath sharply demarcated from scales of caudal peduncle). Pectoral fin tip variably reaching not quite to, or past vertical through anal fin origin, sixth or seventh ray longest. Pelvic fin inserted anterior to vertical through posterior edge of preopercle; outer two rays longer than inner rays; second ray longest, 13.3 (13.3– 24.9)% SL, nearly twice length of subsequent ray, reaching vertical through first dorsal fin origin.
Fresh colour. (Based on images of non-type material; fig. 7A.) Medium to dark reddish brown above, extending ventrally to level of ventral portion of pectoral fin base, white below in smaller individuals, large individuals becoming brown ventrally and often much darker; lateral line not distinctively coloured. Underside of head, jaws and barbel white, tinged with pink to orange, becoming more orange to brown in larger individuals; ventral margin of suborbital dusky to dark. Dorsal and caudal fins of similar colour to brown of sides, anal fin pink or orange in smaller individuals, becoming brown like other median fins in large individuals, dorsal, caudal and anal fins with distinct broad to narrow black margin distally, margin on caudal fin broadest. Pectoral fin orange to brown with faintly darker semi-circular brown blotch basally, covering dorsal 80% of edge of fin proximally. Pelvic fin rays white with pink to orange hue, becoming brownish in large individuals.
Preserved colour. Head and body dusky to dark dusky; underside of head, belly and side adjacent to anal fin pale, especially in small specimens, extent of pale underside less in large individuals. Dorsal, caudal and anal fins dusky to dark dusky, anal fin often less dark than dorsal and caudal; distal edges of dorsal, caudal and anal fins with distinctly dark margins, dark margin on caudal fin broad; pectoral fin broadly dusky basally, becoming pale toward outer margin. Pelvic fin pale dusky.
Etymology. The specific epithet barbatus is Latin for “bearded” in reference to the chin barbel, which is characteristic of this species, its congeners and many other members of the family.
Distribution. Endemic to coastal waters of Australia and New Zealand from Rottnest Island, Western Australia (32° 01' S, 115° 30' E), to Port Stephens, New South Wales (32° 30' S, 152° 35' E), including all of Tasmania and around both the North and South Islands of New Zealand, reaching the Chatham Islands in the east (fig. 3B). A demersal species on rocky bottom at 1 to at least 520 m. Although found at considerable depths in New Zealand waters, this is a shallow reef-dwelling species in southern Australia, where it shelters in caves and beneath overhangs during daylight hours, venturing out at night to feed.
Remarks. Pseudophycis barbata has an overall darker colouration than its congeners, often with a reddish hue in fresh material, and distinct black margins to the dorsal, caudal and anal fins. In particularly dark individuals, the basal portion of the pectoral fin is similarly dark but lacks the distinct black spot present in P. bachus and P. palmata. Pseudophycis barbata is easily separable from P. breviuscula by the more numerous scales (16–22 vs. 7–9) in a transverse row between the dorsal fin origin and lateral line.
As mentioned above under Remarks for P. palmata, McCoy’s (1878: 29) treatment of P. barbata, the first published after Günther’s original description, was largely based on specimens of P. palmata, but the accompanying illustration is of a large specimen of P. barbata. Although Ramsay’s (1881) description of Lotella grandis is inadequate for a conclusive identification of the species, the lone type specimen (AMS I.696) is clearly P. barbata. Early taxonomic confusion resulted in Steindachner (1901: 509) reporting P. barbata from New Zealand as L. grandis, Norman (1937: 55) speculating that P. barbata (as Physiculus barbatus) may be identical with P. bachus, and Graham (1938: 399) and Habib (1975) treating it in New Zealand as P. breviusculus. The last stems from our assumption that P. breviusculus does not occur in the waters of the South Island based on specimens examined and reliable identification records.
