Barnard 1958: 102. <i>Waldeckia kroyeri enoei</i>. — Pirlot, 1936: 268, fig. 105B. — Barnard &amp; Karaman 1991: 542. <b>Material examined.</b> 4 unsexed, AM P77899 (JML 7-10 - 2); 2 unsexed, AM P77898 and 1 immature female, 4.0 mm, AM P78704 (JML 7-10 - 3); 2 unsexed, AM P77897 (JML 83 /7-3-11); 1 unsexed, AM P77900 (QLD 92); 1 unsexed, AM P71054 (QLD 1718). <b>Type locality.</b> Pulau Enu (as Poeloe Enoe), Aru Islands, Indonesia (~ 7°05’S 134°30’E). <b>Description</b>. Based on immature female, 4.0 mm, AM P78704. <b>Head and body.</b> <i>Body</i> without dorsal carina. <i>Head</i> lateral cephalic lobes rounded, with apically rounded margins; eyes reniform. <i>Antenna 1</i> slightly shorter than antenna 2; flagellum with weak 1-field callynophore, robust setae absent from proximal articles; calceoli absent; accessory flagellum with 5 articles. <i>Antenna 2</i> less than 40% of body length; peduncle without brush setae, peduncular article 3 elongate, calceoli absent. <i>Mouthparts</i> forming a subquadrate bundle. <i>Epistome</i> / <i>upper lip</i> fused, broadly rounded. <i>Mandible</i> molar setose with vestigial triturating surface; palp attached extremely proximally, article 3 without A3-setae. <i>Maxilla 1</i> outer plate with setal-teeth in 6/5 arrangement; setal-tooth 7, left and right symmetrical, cuspidate along most of straight inner margin; palp distal margin with apical robust setae. <i>Maxilliped</i> inner plates well developed, greater than half the length of outer plate; outer plates without apical robust setae; palp 4–articulate, article 4 well developed. <b>Pereon.</b> <i>Gnathopod 1</i> minutely parachelate; coxa large, about as long as coxa 2, subrectangular with concave anterior margin; basis slender, moderately setose along anterior margin, bottle-shaped setae present; ischium short; carpus short, subequal in length to propodus, without posterior lobe; propodus margins tapering, palm obtuse, entire, straight; dactylus inner margin not serrated. <i>Gnathopod 2</i> subchelate; carpus longer than propodus; palm large, transverse, concave; dactylus well developed. <i>Pereopod 4</i> coxa with well developed posteroventral lobe. <i>Pereopod 5</i> coxa slightly lobate posteriorly; basis about as long as broad. <i>Pereopod 7</i> basis posterodistally produced less than halfway along merus. <b>Pleon.</b> <i>Epimeron 3</i> posterior margin smooth, posterodistal corner subquadrate. <i>Urosomite 1</i> dorsally straight. <i>Uropod 1</i> rami subequal. <i>Uropod 2</i> rami subequal, inner ramus without marginal constriction. <i>Uropod 3</i> rami distinctly unequal, with plumose setae on each ramus; outer ramus 2–articulate, article 2 short, inner ramus not reaching end of article 1 of outer ramus. <i>Telson</i> distinctly longer than broad, deeply cleft, without dorsal robust setae, with 1 apical robust seta on each lobe. <b>Habitat</b>. Sediment (mud, maerl, sand, shelly sand, coral debris, broken shell, stones), 13 to 34 m depth. <b>Remarks.</b> <i>Waldeckia enoei</i> is the only lysianassid on the GBR with parachelate first gnathopods. The anterior margins of the basis of the first gnathopods have unique bottle-shaped setae which separates <i>W. enoei</i> from all other <i>Waldeckia</i> species and from all other species on the GBR. <b>Distribution</b>. <i>Australia</i>. Queensland: Lizard Island (current study). <i>Indonesia</i>: Aru Islands (Stephensen 1931; Pirlot 1936); Misool Island, Ceram Sea (Pirlot 1936). <i>Timor</i>. North-east coast (Pirlot 1936).
