Type locality. East of Cape Naturaliste , Tasmania, Australia, 40°45.94’S 149°01.62’E GoogleMaps to 40°46.54’S 149°00.27’E, 2400–2500 m depth.

Etymology. Named for the barque Cataraqui lost off King Island in 1845.

Diagnostic description. Antenna 1 peduncular article 1 not or only slightly produced dorsodistally. Mandible incisor present; left lacinia mobilis absent; accessory spine row absent; molar absent. Maxilla 1 outer plate with 3 setal-teeth, setal-teeth without cusps; palp 2-articulate. Maxilliped palp article 2 longer than broad, length 3 x breadth. Gnathopod 1 basis margins subparallel; ischium short, length 1.7 x breadth; carpus long, length 3.1 x breadth, longer than (1.85 x) propodus; propodus subrectangular, length 2.2 x breadth. Pereopods 3 and 4 propodus with long distal locking seta. Pereopod 5 basis expanded posteroventrally, with posteroventral lobe; merus moderately expanded posteriorly. Pereopod 7 basis with posteroventral lobe not extending much beyond ischium; merus posteroventral lobe extending less than halfway along carpus. Pleonite 3 without dorsodistal boss. Epimeron 3 posteroventral corner narrowly rounded. Uropod 1 rami without robust setae. Uropod 3 uniramous; outer ramus 2-articulate. Telson shorter than broad, length about 0.9 x breadth.

Remarks. Clepidecrella cataraqui , C. colliboi and C. ira share the characters of left lacinia mobilis absent and maxilla 1 outer plate with only 3 setal-teeth. Clepidecrella cataraqui can be distinguished from C. colliboi and C. ira by the long distal locking seta on pereopods 3 and 4, the short posteroventral lobe on the basis of pereopod 7, the 2-articulate outer ramus on uropod 3 and the shorter than broad telson.

The holotype female has a non-setose oostegite on pereopod 5 only.

Distribution. South-eastern Australia, in 2400–2500 m depth.
