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

Figure 123. Rocinela runga sp. nov. Holotype. A, dorsal view; B, lateral view; C, head, dorsal view; D, frons; E, pleonites,
oblique lateral view; F, antennule, in situ (dorsal view); G, antenna, in situ (ventral view).
Frontal lamina as wide as long, anteriorly acute.
Mandible molar process distinct flat lobe; palp article
2 with 2 marginal distolateral setae (all with distinctly
bifurcate tips), and 2 long distolateral setae; palp article
3 with 22 setae (all distally bifurcate except distalmost
seta). Maxillule with 6 RS ( large, 5 slender, 2 of which
serrate). Maxilla mesial lobe with 2 hooked RS; lateral
lobe with 2 hooked RS. Maxilliped palp article distomesial
angle with 2 RS ( short, straight, hooked);
article 2 with 2 hooked RS; article 3 with 2 hooked RS
(article 3 proximally fused to article 2).
Pereopod 1 basis 3.2 times as long as greatest width;
ischium 0.6 times as long as basis, inferior margin with 0
RS, superior distal margin with 7 setae (and acute RS);
merus inferior margin with 2 RS (minute), set as two
90
groups, superior distal angle with 6 setae (all simple);
carpus 0.7 times as long as merus, inferior margin with
0 RS; propodus 4.4 times as long as proximal width, propodal
palm simple, without blade or process, inferior
margin with RS (distal; minute); dactylus .0 times as
long as propodus (curved distally). Pereopods 2 and 3
not similar to pereopod (more robust, with +2 RS on
inferior margin of merus; propodus 2.6 times as long
as proximal width, with 2 small RS; dactylus slightly
longer ( .03) than propodus, weakly curved). Pereopod
6 similar to pereopod 7 (but longer). Pereopod 7 basis 3.7
times as long as greatest width, inferior margins with
7 palmate setae; ischium 0.7 as long as basis, inferior
margin with 7 RS (set as , 2, 2 and 2), superior distal
angle with 4 RS, inferior distal angle with 6 RS; merus
