[p.118, Fig.79]. Female (30°45'S, 173°16'E): A, urosome (dorsal); B, P5. Male: C, urosome (dorsal); D, P5 (L = left leg; R = right leg). Female characteristics: Forehead narrows anreriorly in dorsal view; - Posterior metasomal corners angular. ) Caudal rami asymmetrical, left ramus longest. - A1 shorter than the body. - P5 with 1 free segment, asymmetrical, shorter on right, carrying 4 setae, 3 of them apical (median one longest), and 1 external. Male characteristics: P5 asymmetrical, 3-segmented; on right segment 1 with an inner tubercle and 1 distolateral seta; segment 2 with 2 distal setae, 1 internal, 1 external; segment 3 elongate and curved with 4 flutes on inner border; left leg is shorter with last 2 segments hairy on inner border and with some simple setae. On a Southwest Pacific male the right P5 has a 3-segmented exopod with segment 2 with an outer edge spine and inner edge pointed projection; right basipod 2 with an inner-toothed process and with an outer distal plumose seta similar to those on left basipod 2 and exopod segments 1 and 2+3.
