Basipodal segment 2 of the left leg has a protrusion on its inner distal corner. This protrusion carries a row of teeth, variable in number i| and size (3-13), and a small rounded protuberance (Fig. 2m). The right side of the fifth pair of legs has a 2-segmented endopodite and exopodite. Exopodal segment 2 has 2 apical spines and 1 outer subapical spine. The left side of the fifth pair of legs has a 3-segmented exopodite and endopodite. Exopodal segment 3 has 1 outer, apical, and inner spine. Copepodite Stage V. Body shape (Figs. 4j, 1) is as the adult. The cephalosome and metasomal segment 1 are separated; metasomal segments 4 and 5 are fused. The urosome is composed of 4 abdominal segments and the furca. The antennules, 25-segmented. exceed the length of the body by the last 2-3 segments. The first pair of legs has 3-segmented exopodites and 2-segmented endopodites (Fig. 4j). Legs 2 to 4 have 3-segmented exopodites and endopodites. The fifth pairol legs has 2-segmented endopi and exopodites in both sexes digs. 4k. mi ["hi distal segment corresponds to fused segments 2 and 3. In the male Ihe right side of leg 5 is shorter than ihe left. Copepodite Stage IV. The specimens of this stage have a 3-segmented abdomen Oigs. 4c. I). Exopodites and endopodites of legs 1-4 have 3 segments (Fig. 4g). The fifth pair of legs has 1- segmentcd endopodites and exopodites. Distribution. I., pseudo
