Exopod 6 -segmented, segment 1 short without seta, segment 2 elongate bearing enlarged distal seta, segments 3–6 each with 1 seta. Mandible (Fig. 2 B) with degenerate gnathobase. Palp well developed. Endopod 2 -segmented, segment 1 with 2 setae, segment 2 with 8 setae, 5 of which elongate, exopod with 6 setae. Maxillule (Fig. 2 C) reduced with degenerate inner lobes and endopod with 2 small setae. Exopod with 8 setae, praecoxal epipodite with 6 large setae. Maxilla (Fig. 2 D) reduced to a small, knob-like remnant. Maxilliped (Fig. 2 E) sexually dimorphic. Inner setae of syncoxa, basis and endopod segments absent or very reduced; 1 terminal and 2 outer endopod setae enlarged, plumose, 2 outer setae directed towards base of limb as is typical of Paracalanidae, Calanidae and Eucalanidae.
