Holotype, male, 11 mm, ZMH K 33164. Type locality. Weddell Sea, Antarctica (77 °36.0'S 18 °39.3'W). Description. Head, lateral cephalic lobe rounded; eyes reniform. Antenna 1 peduncular article 1 without anterodistal lobe; accessory flagellum with an elongate article 1 (at least twice as long as article 2) partially covering callynophore, 4 -articulate; primary flagellum with weak 1 -field callynophore; calceoli absent. Antenna 2 peduncular article 3 short; articles 3 to 5 not enlarged, brush setae present; calceoli absent. Labrum (epistome and upper lip) separate; epistome produced equally with upper lip, straight; upper lip produced, rounded apically. Mandible molar an (?) asymmetrically reduced column, proximally setose, distally triturating; left lacinia mobilis a long, slender robust seta. Maxilla 1 outer plate setal-teeth in a well-developed 7 / 4 crown arrangement; palp distal margin with apical robust setae. Maxilla 2 inner plate significantly shorter than outer plate. Maxilliped outer plate with 2 long (one slender, one broad) apical robust setae. Gnathopod 1 coxa large, about as long as coxa 2, subrectangular with slightly concave anterior margin, slightly expanded distally; basis sparsely setose along anterior margin; ischium short; propodus margins subparallel, palm transverse or slightly acute, entire, convex, minutely serrate; dactylus simple. Gnathopod 2 subchelate; propodus palm transverse, straight; dactylus fitting palm. Pereopod 4 coxa with a well-developed posteroventral lobe. Pereopod 5 coxa about as long as broad, producing slight posterior lobe; basis longer than broad, posterior margin weakly serrate; carpus 2 × longer than wide; propodus 3 × times longer than wide. Pereopod 6 carpus 2.5 × longer than wide; propodus 3 × times longer than wide. Pereopod 7 basis posterior margin evenly ...
