HOLOTYPE, female, 4.2 mm, MV J61505, south of Point Hicks, Victoria, Australia, 38°19.60'S 149°24.30'E, 930 m, rock, rubble, clay, sand, biogenic sediment, WHOI epibenthic sled, 23 July 1986, M.F. Gomon <i>et al.</i>, RV <i>Franklin</i>, stn SLOPE 33. PARATYPES: 1 female and 2 males, MV J61506, south of Point Hicks, Victoria, Australia, 38°21.90'S 149°20.00'E, 1000 m, WHOI epibenthic sled, 23 July 1986, G.C.B. Poore <i>et al.</i>, RV <i>Franklin</i>, stn SLOPE 32; 1 female, AM P.69011, east of Broken Bay, New South Wales, Australia, 33°30’S 152°09’E to 33°33’S 152°11’E, 922–1015 m, beam trawl, 12 February 1986, R. T. Springthorpe, FRV <i>Kapala</i>, stn K86-01-08. <b>Type locality</b>. South of Point Hicks, Victoria, Australia, 38°19.60'S 149°24.30'E, 930 m depth. <b>Etymology</b>. Named for the interstate passenger liner TSS <i>Kanowna</i>, which sank off Wilsons Promontory in 1929 with no loss of life. <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 5 setal-teeth, most setal-teeth cuspidate; palp 2-articulate. <b> <i>Maxilliped</i> palp article 2 longer than broad</b> , length 2 x breadth. <i>Gnathopod 1</i> basis margins subparallel; <b>ischium very long</b>, length 4.3 x breadth; carpus very long, length 4.8 x breadth, subequal to (1.1 x) propodus; propodus tapered distally, length 5.3 x breadth. <i>Pereopods 3 and 4</i> propodus with short distal locking seta. <b> <i>Pereopod 5</i> basis expanded posteroventrally</b> , with posteroventral lobe; merus moderately expanded posteriorly. <b> <i>Pereopod 7</i> basis with posteroventral lobe not extending much beyond ischium</b> ; merus posteroventral lobe extending more than halfway along, but not beyond, carpus. <i>Pleonite 3</i> without dorsodistal boss. <i>Epimeron 3</i> posteroventral corner broadly rounded. <i>Uropod 1</i> rami with robust setae. <i>Uropod 3</i> biramous; inner ramus about 0.5 x outer ramus; outer ramus 2-articulate. <i>Telson</i> about as long as broad, length about 1 x breadth. <b>Remarks</b>. <i>Kerguelenia kanowna</i> belongs to a group of species (<i>K. antiborealis, K. borealis, K. leura, K. ochotica</i> and <i>K. matilda</i>) in which the basis of pereopod 5 is expanded posteroventrally and gnathopod 1 carpus is subequal to the propodus. It is most similar to <i>K. antiborealis</i> from Marion Island in the Southern Ocean. It can be distinguished from that species by the greater size of pereopod 5 merus and of pereopod 7 basis in <i>K. antiborealis</i>. The non-ovigerous holotype female has a setose oostegite on pereopod 5 only. <b>Distribution</b>. South-eastern Australia, in 922–1015 m depth.
