Description
Dorsal spines (total): 5; Dorsal soft rays (total): 21; Anal spines: 1; Anal soft rays: 16-17; Pectoral fin rays: 18; Lateral line scales: 57-60; Body elongate, cylindrical anteriorly and gradually compressed posteriorly. Head pointed anteriorly, 3.4 (3.3–3.4) in SL. Snout longer than orbital diameter, 2.3 (2.4–2.9) in HL. Orbital diameter more than 2 times interorbit, 5.0 (4.1–5.2) in HL. Interorbit broad and flat, 11.5 (8.7–13.9) in HL. Mouth slightly oblique and large, the maxilla reaching beyond a vertical through anterior margin of eye, length 2.5 (2.4–2.7) in HL; tip of lower jaw about equal to that of upper jaw, length of lower jaw 2.5 (2.2–2.3) in HL. Upper jaw with an outer row of canine teeth, becoming smaller posteriorly, and a medial tooth band comprised of small villiform teeth, narrowing to a single row posterirorly. Lower jaw with 4 recurved canine teeth anteriorly on each side (but anteriormost on right side detached), fourth largest. Subsequent tooth band on lower jaw of an outer row of canine teeth and medial villiform teeth; middle portion of outer row with several large canine teeth; villiform teeth restricted to anterior portion of lower jaw. Vomer with several rows of villiform teeth. Palatine without teeth. Gill membranes free of isthmus, with a broad free fold. Opercle with a single, strong, retrorse spine dorsally. Outer margin of preopercle smooth and that of subopercle with serrations in the middle portion. Lateral line slightly arched over pectoral fin, then extending along middle of body to the basal portion of the caudal fin. Scales on body and opercle ctenoid; those on nape, abdomen and area around pelvic fin cycloid. Cheek with small embedded scales. Snout, interorbit, posterior portion of eye and lower surface of head without scales. Basal portion of pectoral fin with small ctenoid and cycloid scales. Caudal fin, except for posterior third, covered by small ctenoid and cycloid scales. Dorsal, anal and pelvic fins without scales. Origin of dorsal fin above third lateral line scale. Membrane of spinous dorsal connected to first soft dorsal ray opposite tip of last spine. Origin of anal fin below base of fifth soft dorsal ray. Pectoral fin rounded, length 4.9 (4.7–5.3) in SL. Pelvic fin reaching origin of anal fin, length 4.5 (3.8–4.6) in SL. Caudal fin weakly rounded, upper edge slightly elongated posteriorly, length 4.5 (4.4–5.1) in SL. Max length: 20.8 cm SL (male); 11.4 cm SL (female). Depth range: 1 - 27 m.
Color
2–6 oblique brownish bands on the lower cheek region, 3–4 ocelli and a series of several blackish and brownish spots on the lower portion of the body in males; and no B5 spot on cheek, 7–8 ocelli and brownish spots or patches between ocelli in females and juveniles.
Etymology
Parapercis: from Greek prefix, para = resembling to + from Greek, perke = perch. Perch is a common name for fish of the genus Perca, freshwater gamefish belonging to the family Percidae.
queenslandica: the specific name derives from the type locality - Capricorn Group, One Tree Island, Queensland, Australia.
Original description: Parapercis queenslandica Imamura & Yoshino, 2007 - Type locality: Capricorn Group, One Tree Island, Queensland, Australia (23°30S, 152°05E), 1 m depth, 10 Dec. 1966.
Distribution
Western Pacific: Queensland, Australia and New Caledonia.
Similar species
Parapercis hexophtalma (Cuvier, 1829) - Reported from Red Sea and Idian Ocean : East Africa, South Africa, Seychelles, Madagascar and Mascarenes, Maldives, Somalia, Sri Lanka and Thailand.
Parapercis pacifica (Imamura & Yoshino, 2007) - Reported from Western Pacific: Japan and Ryukyu Islands, Taiwan.
Parapercis xanthogramma (Imamura & Yoshino, 2007) - Reported from Central Pacific: Fiji, Tonga and Western Samoa. The males of Parapercis queenslandica and Parapercis xanthogramma can be distinguished from each other by the coloration of the cheek region: the former has 2–6 oblique brownish bands restricted to the lower cheek region, whereas the latter has 4–7 oblique pale (yellow when fresh) entire bands distributed on the cheek region. The female Parapercis queenslandica is also separable from that of Parapercis xanthogramma in lacking a B5 spot on the cheek region (vs. present).
