Waite on HMCS Thetis (AM G2 60). desCription of new zeaLand speCimens: Body 3.4 times as long as greatest width, dorsal surfaces polished in appearance, widest at pereonite 5, lateral margins subparallel. Rostral point projecting anteriorly, not ventrally folded. Eyes large, not medially united, separated by about 36% width of head; each eye made up of ~ 6 transverse rows of ommatidia, each row with ~9 ommatidia; eye colour pale brown. Pereonite 1 and coxae 2–3 each with posteroventral angle with small distinct produced point (ventral); coxae 5–7 with incomplete oblique carina. Pleon with pleonite visible in dorsal view; pleonite 4 with posterolateral margins extending to but not beyond posterior margin of pleonite 5; pleonite 5 with posterolateral angles free, not overlapped by lateral margins of pleonite 4. Pleotelson 0.7 times as long as anterior width, dorsal surface with longitudinal carina on distal third; lateral margins weakly convex, deeply serrate (with 13–15 flat marginal spines), posterior margin subtruncate, with 3– 5 RS.

Frontal lamina flat, as wide as long, lateral margins converging posteriorly, anterior margin rounded, forming median angle, posterior margin not abutting clypeus. Pereopod 1 basis .4 times as long as greatest width; ischium 0.5 times as long as basis, inferior margin with 0 RS, superior distal margin with 2 RS (acute); merus inferior margin convex and thickened, with 0 RS, superior distal angle with 2 RS; carpus 0.9 as long as merus; inferior margin with 0 RS; propodus .4 times as long as proximal width, inferior margin with 0 RS, propodal palm with small distal lobe (concave), dactylus abruptly hooked, .0 as long as propodus. Pereopod 2 ischium inferior margin with RS (stout), superior distal margin with 2 RS; merus inferior margin with 6 RS (and 2 slender setae), set as two groups (ill- defined), superior distal margin with 2 acute RS; carpus longer than that of pereopod , with inferodistal lobe, inferodistal angle with RS, propodus without large club-shaped distal robust seta. Pereopod 3 not similar to pereopod 2 (dactylus slender and claw-like); propodus with large club-shaped distal robust seta. Pereopod 6 similar to pereopod 7 (but more robust with longer RS on inferior margins). Pereopod 7 basis 3.2 times as long as greatest width, inferior margins with 6 palmate setae (many missing); ischium 0.7 as long as basis, inferior margin with 9 RS (set loosely as , 4 and 4), superior distal angle with 5 RS, inferior distal angle with 0 RS; merus 0.7 as long as ischium, 2.7 times as long as wide, inferior margin with 9 RS (set loosely as , 4 and 4), superior distal angle with 6 RS, inferior distal angle with 6 RS; carpus 0.9 as long as ischium, 5.3 times as long as wide, inferior margin with 9 RS (set as 2, 2, , , 2 and ), superior distal angle with 3 RS, inferior distal angle with 7 RS; propodus 0.8 as long as ischium, 7.4 times as long as wide, inferior margin with 5 RS (set as , , 2 and ), superior distal angle with slender setae, inferior distal angle with 4 RS. Penes low tubercles; penial openings separated by 0% of sternal width. Uropod peduncle ventrolateral margin with 2 RS (and ~5 plumose setae), posterior lobe about threequarters as long as endopod. Uropod rami extending beyond pleotelson (lateral and mesial margins deeply serrate), marginal setae in single tier, apices acute. Endopod apically not bifid, lateral margin straight (deeply serrate), without prominent excision, proximal lateral margin with 5 RS (margin not divided, with 5 prominent flat spines), mesial margin straight (deeply serrate), with 2 RS (and 2 prominent flat spines). Exopod not extending to end of endopod, 3.2 times as long as greatest width, apically not bifid; lateral margin straight (deeply serrate), with 5 RS (and 5 prominent flat spines); mesial margin straight, with 1 RS.
