Basis of mandible (Fig. 4E) with 4 setae. Maxillule (Fig. IE) with 1 new naked seta on inner lobe. Nauplius VI Body length : mean ± standard deviation = 241 ± um (range 255 to 224 um, n= 16), mean body width 152 ± (range 143 to 162 um). Body (Fig. IF) similar to nauplius V, differing as follows: innermost pair of caudal setae longest, middle pair of setae plumose, shortest setae naked and laterally located. Third segment of antennule (Fig. 2F) with total of 13 setae, including 5 new setae, plus ornamentation of several long spinules. Endopod of antenna with 9 setae (Fig. 3F), with 1 extra seta in proximal group. Mandible (Fig. 4F) with minor changes in ornamentation of basal setae. Maxillule with 1 new seta on inner lobe, and with 3 spinules on outer margin. Anlagen of post-maxillulary limb pairs apparent on ventral surface of body (Fig. IF). Description of Copepodid Stages Copepodid I Body length : mean ± standard deviation = 382 ± um (range 373 to 404 um, n=10), mean body width 146 ± um (range 134 to 152 um, n=10). Body 5-segmented (Fig. 5A), comprising cephalothorax and 4 postcephalothoracic trunk somites. Second trunk somite with 1 seta at posterolateral angles representing third swimming legs. Antennule, antenna, mandible, maxillule, maxilla, maxilliped and first and second swimming legs present. Caudal rami (Fig. 6A) as broad as long. Each ramus armed with 6 setae, ornamented with spinular row on ventral surface, outermost seta plumose with spinular row at base, 1 naked seta located on dorsal surface posteriorly, 1 short naked seta close to.
