Named for the wooden schooner <i>Ira</i> which went ashore in gale conditions on Ninth Island, Bass Strait in 1868. <b>Diagnostic description</b>. <i>Antenna 1</i> peduncular article 1 not or only slightly produced dorsodistally. <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, 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; <b>ischium short</b>, length 1.5 x breadth; carpus long, length 3 x breadth, longer than (1.4 x) propodus; propodus tapered distally, length 2.7 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 with robust setae. <b> <i>Uropod 3</i> biramous</b> ; inner ramus about 0.7 x outer ramus; outer ramus 1-articulate. <i>Telson</i> longer than broad, length about 1.1 x breadth. <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 ira</i> can be distinguished from <i>C. cataraqui</i> and <i>C. colliboi</i> as discussed under those species. The non-ovigerous holotype female has a non-setose oostegite on pereopod 5 only. <b>Distribution</b>. South-eastern Australia, in 500–1000 m depth.
