Etymology. Named for the paddle steamer Euroka wrecked off Long Reef in 1913.

Diagnostic description. Antenna 1 peduncular article 1 not or only slightly produced dorsodistally. Mandible incisor absent; left lacinia mobilis absent; accessory spine row absent; molar absent. Maxilla 1 outer plate with 3 setal-teeth, most setal-teeth without cusps; palp 2-articulate. Maxilliped palp article 2 longer than broad, length 1.5 x breadth. Gnathopod 1 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. Pereopods 3 and 4 propodus with short distal locking seta. Pereopod 5 basis linear, without posteroventral lobe; merus strongly expanded posteriorly. Pereopod 7 basis with posteroventral lobe extending beyond merus; merus posteroventral lobe extending beyond carpus. Pleonite 3 without dorsodistal boss. Epimeron 3 posteroventral corner narrowly rounded. Uropod 1 rami without robust setae. Uropod 3 rami absent. Telson shorter than broad.

Remarks. Kerguelenia euroka belongs to a group of species ( K. adeliensis , K. antarctica , K. compacta , K. kawatiri and K. macropoda ) in which the basis of pereopod 5 is linear. It is most similar to K. macropoda 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.

Distribution. South-eastern Australia, in 49–176 m depth.
