Gomon <i>et al.</i>, RV <i>Franklin</i>, stn SLOPE 47. PARATYPES: 1 specimen, MV J61496, same data as holotype; 2 specimens, AM P.81163 and 2 specimens, MV J61497, 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; 3 males, MV J61498, 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. <b>Type locality</b>. Off Freycinet Peninsula, Tasmania, Australia, 41°58.60'S 148°38.80'E, 500 m depth. <b>Etymology</b>. Named for the steamship <i>Colliboi</i> beached on Woolnorth Point, Tasmania in 1932. <b>Diagnostic description</b>. <b> <i>Antenna 1</i> peduncular article 1 not or only slightly produced dorsodistally</b> . <i>Mandible</i> incisor present; 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 1.9 x breadth. <i>Gnathopod 1</i> basis margins subparallel; ischium short, length 1.6 x breadth; carpus long, length 3 x breadth, longer than (1.5 x) propodus; propodus tapered distally, length 2.4 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. <i>Pereopod 7</i> basis with posteroventral lobe extending about halfway along merus; merus posteroventral lobe extending less than halfway along 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> uniramous; outer ramus 1-articulate</b> . <i>Telson</i> longer than broad, length about 1.3 x breadth. <b>Male</b>. Antenna 1 with strong 2-field callynophore. <b>Remarks</b>. <i>Clepidecrella cataraqui</i>, <i>C. colliboi</i> and <i>C. ira</i> share the characters of left lacinia mobilis absent and maxilla 1 outer plate with only 3 setal-teeth. <i>Clepidecrella colliboi</i> can be distinguished from <i>C. ira</i> by the lack of robust setae on the rami of uropod 1 and the uniramous uropod 3. It can be distinguished from <i>C. cataraqui</i> by the presence of cusps on one tooth of maxilla 1 outer plate setal-teeth, the slightly tapered propodus of gnathopod 1, the presence of a posteroventral lobe on the basis of pereopod 7 and the longer than broad telson. The ovigerous holotype female has an oostegite on pereopod 5 only. <b>Distribution</b>. South-eastern Australia, in 500–1000 m depth.
