Pygodelphys novaeseelandiae (Schellenberg, 1922) (Figs. 62, 63) Material examined . 1 ♀ (dissected and figured) from Polycarpa sp., Antipodes Island, New Zealand, Eltanin 27, Stn 1850 (49°40’S 178°53’E), depth 476-540 m, 1967. Supplementary description of female . Body (Fig. 62A) strongly flexed ventrally with brood pouch greatly expanded lengthwise, extending beyond tips of caudal rami. Body length 3.45 mm measured from anterior margin of cephalosome to distal end of caudal rami. Prosome longer than body length, 3.94 mmlong measured from anterior margin of cephalosome to posterior end of brood pouch. Freeurosome (Fig. 62B) 5-segmented and graduallynarrowing posteriorly; Comprising short genital somite and 4 free abdominal somites. Genital and first abdominal somites each ornamented with rows of minute spinules on ventral surface. Caudal ramus (Fig. 62C) slightly curved, about 6.2 times longerthan wide (409×66 μm) and twice as long as anal somite, slightly narrowing distally; armed with 6 naked setae, outer lateral setae located at 39% of ramus length. Rostrum (Fig. 62D) broad in proximal third, strongly tapering towards apex in distal two-thirds. Antennule (Fig. 62E) 9-segmented; armatureformula 3, 16, 6, 4, 4, 2+aesthetasc, 1, 2+aesthetasc, and 7+aesthetasc; setae crowded, most large and naked; 2 pinnate setaeon first and 1 on second segments. Antenna (Fig. 62F) 3-segmented; coxa short and unarmed; allobasis with 2 equally long, slender setae (1 unilaterally weakly pinnate and 1 naked) on outer margin representing exopod, and 1 seta derived from first endopodal segment; compound distal endopodal segment about twice as long wide (106×50 μm), shorter than allobasis, armed with 11 setae (all attenuated at tip) plus strong terminal claw. Labrum (Fig. 62G) with setulose, roundly produced posterolateral corners and several spinules on midposterior border. Mandible (Fig. 62H) with 6 teethand 2 small setae on coxal gnathobase and 1 small spinule between proximal second and third teeth; basis with 1 seta and setules on ...
