Figure 37. Aegapheles copidis sp. nov. Holotype. A, pereopod 7; B, pereopod 7, propodus and distal margin of carpus, mesial side; C, pleopod ; D, pleopod 2; E, uropod, in situ; H, uropod exopod, ventral view, in situ. 3–5 each with distolateral point; pleopods 2–4 peduncle distolateral margin without prominent acute RS. Uropod peduncle ventrolateral margin with 2 RS, posterior lobe about one-half as long as endopod. Uropod rami with apices narrowly rounded. Endopod apically not bifid, lateral margin proximally convex, with prominent excision, positioned about three- quarters of the way along ramus, proximal lateral margin with 2 RS, distal lateral margin with 4 RS, mesial margin weakly convex, with 6 RS. Exopod extending 72 to end of endopod, 3.9 times as long as greatest width, apically not bifid; lateral margin weakly convex, with RS; mesial margin sinuate, proximally concave, with 4 RS. femaLe: Not known. size: Holotype 22 mm, a mature male; females probably larger.
Variation: The left and right uropodal exopod lateral margins had 0 and robust setae. The robust setae on the posterior margin of the pleotelson are apparently uneven though some may be missing; the probable number is 0 or 2. remarks: Aegapheles copidis sp. nov. can be identified by the prominent propodal blade on pereopods –3 together with the wide frontal lamina, and the relatively slender uropodal endopod, the lateral margin of which is weakly excavate; in addition the pleotelson apex extends only a little way beyond the posterior of the uropods. There are three species of Aegapheles that have a propodal blade on pereopods –3. Aegapheles copidis has a longer propodal blade, shorter uropod exopod and weakly excised endopod lateral margin in comparison to A. kixalles Bruce, 2004; A. musorstom Bruce, 2004 has a symmetrically ovate frontal lamina, wide uropodal exopod which is longer than the endopod, pereopods 2 and 3 with a single continuous row of robust setae on the inferior margin of the merus, and longer robust setae on pereopods 5–7. The tropical Aegapheles trulla Bruce, 2004 has a similar number of robust setae on the merus of pereopods –3 but these are not arranged in two rows; in addition the uropodal endopod lateral margin is weakly excised, uropodal exopod is very wide and the frontal lamina sub-circular. The single specimen was minimally dissected as, though very recently collected, high-grade absolute ethanol preservation had rendered it exceptionally brittle and fragile. The antenna, antennule, mouthparts and pleopods show few differences at species level, and direct observation suggests that these appendages are generally similar to those of other species of the genus (see Bruce 2004a). prey: No records. distribution: West Norfolk Ridge, northeastern New Zealand; 52 –539 metres. etymoLogy: The epithet is the Latin copidis (cleaver, kitchen knife), alluding to the wide propodal blade on the anterior pereopods. Aegapheles hamiota (Bruce, 2004) comb. nov.

Pleotelson . times as long as anterior width, dorsal surface without longitudinal carina; lateral margins convex, smooth, posterior margin with – 6 RS. Antennule peduncle article 2 without anterodistal lobe; flagellum extending to mid-point of eye. Antenna peduncle article 2 inferior surface with distinct longitudinal suture; flagellum extending to posterior of pereonite . Frontal lamina flat, longer than greatest width, oval, anterior margin rounded, without small median point, posterior margin not abutting clypeus. Pereopod 1 merus inferior margin with 5 RS, set as three groups (of , 2 and 2), superior distal angle with 7 RS (long acute); carpus 0.6 as long as merus, inferior margin with 0 RS; propodus .9 times as long as proximal width, inferior margin with 0 RS, propodal palm with small distal lobe, dactylus smoothly curved, .3 as long as propodus. Pereopod 2 merus inferior margin with 9 RS, set as single row (with separation of distal 2), superior distal margin with 5 acute RS (long acute); carpus longer than that of pereopod , with inferodistal lobe, inferodistal angle with RS. Pereopod 3 similar to pereopod 2. Pereopods 5–7 inferior margins of ischium–carpus with long acute RS, superior margins of ischium–carpus with long, stiff, acute setae. Pereopod 7 basis 3.3 times as long as greatest width, inferior margins with 6 palmate setae; ischium 0.5 as long as basis, inferior margin with 0 RS (7 long and 3 short), superior distal angle with 0 RS (5 stout lateral and 5 long mesial), inferior distal angle with 0 RS (6 stout lateral and 4 long mesial); merus .0 as long as ischium, .9 times as long as wide, inferior margin with 5 RS (9 long and 6 short), superior distal angle with 5 RS (3 stout lateral and 2 long mesial), inferior distal angle with 8 RS (3 stout lateral and 5 long mesial); carpus .0 as long as ischium, 3.0 as long as wide, inferior margin with 0 RS (7 long and 3 short), superior distal angle with 0 RS (3 stout lateral and 7 long mesial), inferior distal angle with RS (4 stout lateral and 7 long mesial); propodus 0.8 as long as ischium, 3.5 times as long as wide, inferior margin with 6 RS (4 long and 2 short), superior distal angle with 6 slender setae ( plumose), inferior distal angle with 4 RS. Penes low tubercles; penial openings separated by 6% of sternal width. Uropod peduncle ventrolateral margin with 2 RS (short), posterior lobe about three-quarters as long as
