C.E. Holmes and D.S. Horning on FV President Kennedy , 26 Nov.1974 . Paratypes – 2 females (ovigerous), AM P54121 ; 1 female (ovigerous), AM P54122 ; 3 females (ovigerous), AM P54123 ; all material collected from the type locality. Type locality. – West side of Main Island , 48 07’S 166 38’E , The Snares , New Zealand subantarctic, bryozoans and sponges on lobster pot, 146 m . Description. – Head laterocephalic margin with an acute spine, ventrolateral corner narrowly rounded; eyes round or ovate. Antenna 1 peduncular article 1, distoventral spine, as long as peduncular article 2; peduncular article 2 short, about 1.1 x as long as broad, distoventral spine, much longer than peduncular article 3. Antenna 2 peduncular article 4 with distoventral spine reaching about half way along article 5; article 5 with short distoventral spine. Mandible molar reduced. Maxilla 1 palp reduced, 1-articulate, with a long apical seta. Maxilliped palp present, with 1 article, with a long apical seta. Pereon . Body with sharply raised pereonal carina forming a dorsal keel, without spines or lateral plaques, pleon with very small mid-dorsal processes. Pereonite 1 enlarged, produced over head. Gnathopod 1 coxa straight, ventrally rounded. Gnathopod 2 coxa ventrally rounded; carpus weakly lobate posterodistally along propodus. Pereopod 3 coxa long, ventrally rounded. Pereopod 4 coxa short, ventrally rounded. Pereopod 6 coxa posteroventral corner subquadrate. Pereonite 7 with a small apically acute dorsodistal spine. Pleon . Pleonite 1 with a small apically subquadrate dorsodistal carina. Pleonite 2 with a small apically rounded dorsodistal carina. Pleonite 3 with a narrow apically rounded mid-dorsal carina. Epimeron 1 posteroventral corner rounded. Epimeron 2 posteroventral corner rounded. Epimeron 3 posterior margin excavate, posteroventral corner produced into a curved spine. Telson apically acute. Remarks. – Curidia knoxi differs from the other three Curidia species in the short distoventral spine on antenna 2 peduncular article 4, which is only half length of article 5, whereas it is two thirds the length or longer than article 5 in the other species. Both C. magellanica and C. debrogania also have a very long distoventral spine on antenna 2 peduncular article 5, whereas it is absent or rudimentary in C . knoxi and C. ramonae . Distribution. – New Zealand subantarctic. Etymology. – Named for Professor George Knox, in recognition of his contribution to the biogeography of this area.
