PARATYPES: 1 female, 3.4 mm, AM P.69004, type locality; 1 female, 2.5 mm, AM P.69005, east of Merimbula, New South Wales, Australia, 36°52.5’S 150°18.1’E, 149–152 m, trawl, 4 September 1994, P.B. Berents, FRV <i>Southern Surveyor</i>, stn 05/94/145; 1 female, 2.4 mm, MV J61503, 66 km south of Rodondo Island, central Bass Strait, Australia, 39°48.6'S 146°18.8'E, 82 m, sand, silt and mud, epibenthic sled, 13 November 1981, R. Wilson, RV <i>Tangaroa</i>, stn BSS 158S; 1 female, 2.8 mm, MV J61504, 6 km west of Currie, King Island, western Bass Strait, Australia, 39°54.7'S 143°43.4'E, 49 m, coarse sand, 21 November 1981, R. Wilson, RV <i>Tangaroa</i>, stn BSS 196. <b>Type locality</b>. East of Long Reef Point, New South Wales, Australia, 33°46’S 151°43’E, 176 m depth. <b>Etymology</b>. Named for the paddle steamer <i>Euroka</i> wrecked off Long Reef in 1913. <b>Diagnostic description</b>. <i>Antenna 1</i> peduncular article 1 not or only slightly produced dorsodistally. <i>Mandible</i> incisor absent; left lacinia mobilis absent; accessory spine row absent; molar absent. <i>Maxilla 1</i> outer plate with 3 setal-teeth, most setal-teeth without cusps; palp 2-articulate. <i>Maxilliped</i> palp article 2 longer than broad, length 1.5 x breadth. <i>Gnathopod 1</i> basis margins subparallel; ischium long, length 3.7 x breadth; carpus long, length 2.4 x breadth, subequal to (1 x) propodus; propodus tapered distally, length 3.4 x breadth. <i>Pereopods 3 and 4</i> propodus with short distal locking seta. <b> <i>Pereopod 5</i> basis linear</b> , without posteroventral lobe; merus strongly expanded posteriorly. <i>Pereopod 7</i> basis with posteroventral lobe extending beyond merus; merus posteroventral lobe extending beyond carpus. <i>Pleonite 3</i> without dorsodistal boss. <i>Epimeron 3</i> posteroventral corner narrowly rounded. <i>Uropod 1</i> rami without robust setae. <b> <i>Uropod 3</i> rami absent</b> . <i>Telson</i> shorter than broad. <b>Remarks</b>. <i>Kerguelenia euroka</i> belongs to a group of species (<i>K. adeliensis, K. antarctica, K. compacta, K. kawatiri</i> and <i>K. macropoda</i>) in which the basis of pereopod 5 is linear. It is most similar to <i>K. macropoda</i> from Madagascar but can be distinguished from that species by the greater size of pereopod 5 merus and the more distal production of the posteroventral lobe of pereopod 7 merus. The holotype female, although ovigerous, has no oostegites. <b>Distribution</b>. South-eastern Australia, in 49–176 m depth.
