description: <i>Lepidepecreum dampieri</i> n.sp. Figs. 14–16 <b>Type material</b>. HOLOTYPE, male, 3.5 mm, NMV J7670, between Port Hedland and Dampier, North West Shelf, Western Australia, eastern Indian Ocean, 19°05'00"S 117°26'00"E to 19°05'00"S 117°46'23"E, 120–122 m, muddy sand, dredge, 6 December 1983, G.C.B. Poore &amp; H.M. Lew Ton, FRV <i>Soela</i> stn S03/83 [NMV stn NWA-52]. <b>Type locality</b>. Between Port Hedland and Dampier, North West Shelf, Western Australia, eastern Indian Ocean, 19°05'00"S 117°26'00"E to 19°05'00"S 117°46'23"E, 120– 122 m depth. <b>Description</b>. Based on holotype male, 3.5 mm. Body expanded to form a lateral bulge. <i>Head with lateral cephalic lobe a semidome, apically subacute</i>. <i>Antenna 1 peduncular articles 1 and 2 without anterodistal lobe;</i> accessory flagellum 2-articulate; flagellum with strong 2-field callynophore [not known for female]; robust setae absent from proximal articles; calceoli present. Antenna 2 peduncular article 3 elongate; flagellum elongate; calceoli present. Epistome/upper lip [not known]. Mandible molar columnar with oval, fully triturating surface; mandibular palp attached proximally, article 3 withoutA3-setae. Maxilla 1 outer plate with setal-tooth 7 [symmetry unknown] cuspidate distally; palp distal margin with apical robust setae. Maxilliped outer plate with 1 short, slender apical robust seta. <i>Gnathopod 1</i> subchelate; coxa large, about as long as coxa 2, subrectangular with straight anterior margin; <i>basis sparsely setose along anterior margin</i>; ischium short; carpus long, subequal in length to propodus, without posterior lobe; propodus margins subparallel, <i>palm acute, entire, straight. Gnathopod 2 palm slightly obtuse</i>. <i>Pereopod 4 coxa without distinct lateral ridge</i>, with a well-developed posteroventral lobe. <i>Pereonite 5 dorsally smooth. Pereopod 5 coxa without distinct lateral ridge, without umbo, basis about as long as broad</i>. <i>Pereopod 7 basis posterodistally produced beyond merus</i>. <i>Pleonite 1</i> without mid-dorsal carina, <i>not produced dorsodistally. Pleonite 2</i> without mid-dorsal carina, <i>not produced dorsodistally. Pleonite 3</i> with mid-dorsal carina, <i>produced dorsodistally, apically acute, posterodorsal margin produced. Epimeron 3</i> posterior margin smooth, <i>posteroventral corner subquadrate.</i> Urosomite 1 with deep notch and a narrow vertically produced acute spine. <i>Uropod 3 inner and outer rami well developed; outer ramus article 2 short</i>; with plumose setae on each ramus. <i>Telson moderately cleft</i>, with dorsal robust setae, with 1 apical robust seta on each lobe. <b>Etymology</b>. Named for the English privateer William Dampier, who visited northwestern Australia in 1688 and 1699 and has been described as Australia’s first naturalist. <b>Remarks</b>. <i>Lepidepecreum dampieri</i> is also one of a group of seven species in which the basis of pereopod 7 is developed beyond the merus. <i>Lepidepecreum dampieri</i> is most similar to <i>L. baudini</i> (see <i>L. baudini</i> remarks). <b>Distribution</b>. North West Shelf, Australia, eastern Indian Ocean; 120–122 m depth.
