The Marine Fauna of New Zealand: Isopoda, Aegidae (Crustacea)

Figure 106. Rocinela garricki Hurley, 957. Male, 5.5 mm, Camp Bay, NIWA 23855. A, dorsal view; B, lateral view;
C, pleonites –5, lateral margin; D, head, dorsal view; E, antennule; F, antenna peduncle.
straight, with PMS on distal margin only, mesial margin
with PMS on distal two-thirds; peduncle mesial
margin with 6 coupling hooks. Pleopod 2 appendix
masculina with straight margins, 0.5 times as long as
endopod (basally fused), distally bluntly rounded.
Pleopods 2–5 peduncle distolateral margin without
acute RS.
Uropod peduncle ventrolateral margin with 2 RS,
posterior lobe about one-third as long as endopod. Exopod
at angle of about 35° to endopod, rami extending
to pleotelson apex, marginal setae in two tiers. Endopod
lateral margin weakly convex, lateral margin with 3 RS,
mesial margin straight and distally rounded, with 3 RS.
Exopod not extending to end of endopod, 2.4 times as
long as greatest width; lateral margin weakly convex
(weakly serrate), with 8 RS; mesial margin convex, with
0 RS; distal margin with distinct distal point.

size: Males from 5.5 to 9.5 mm; ovigerous females
6.5–22.0 mm (mean 20 mm, n = 5); single manca 5.5
mm.
femaLe: Generally similar to the male, with the rostrum
less strongly produced.
Variation: The figures here include the holotype, therefore
the uropod and pleotelson details are taken from
the original description. Pleotelson (n = 8) RS 9– 2, with
0 and most frequent, each at 38%. Uropod exopod
(n = 4) mesial margin without RS in all specimens;
lateral margin 7–9 RS with 8 (57%) most frequent, 7
occurring 3 times and 9 once. Uropod endopod mesial
margin (n = 3) varied from 0–5 to with 2 (3 %) and 3
(39%) the most frequent, 0 occurring twice, 4 and 5 each
occurring once; lateral margin (n = 4) with 2–5 with
