setae armed with marginal spines, right palp 
bearing 5 slightly shorter terminal setae and 1 
ventral seta, the right outer plate bearing 9 stout 
setae, some with marginal spines others strongly 
dentate, or with a mix of spines and denticles, the 
outer plate of both bearing an apico-medial cluster 
of fine setae basal to the first and second terminal 
spines. Inner plate with 10 distal plumose setae on 
both sides. Second maxilla: inner plate bearing 
sparse facial and lateral pubescence, outer plate 
naked. Pubescence of inner plate extending across 
the face basal to an oblique row of 15 plumose

medial marginal row of 7 slender naked setae, a 
distal sub-marginal row of plumose setae, and 
distal marginal row of mixed plumose setae and 2 
stout rastellate setae. The outer plate without 
medial or lateral setae and apically a sub-marginal 
row of 7 slender naked setae and 10 long, stout 
rastellate setae. Maxilliped (Figure 1), Inner plate 
bearing few ventro-facial spines. First gnathopod 
(Figure 5) coxal plate with 2 short setae ventrally. 
Article 5 (carpus) not lobate, bearing strong 
posterior naked and rastellate setae. Propodus 
trapezoidal, expanding slightly apically, longer 
than wide (70:50), posterior margin bearing a row 
of 6 slender setae, the comer of the palm without 
lateral or medial spines, but a sub-distal row of 7 
moderate, slender setae. Palm transverse, slightly 
convex posteriorly, with few adjacent setae, 
without marginal spination, or anterior excavation 
or marginal cusps. Dactyl reaching the palmar 
comer without recumbent inner tooth spines, but 
bearing 2 accessory spinules and a nail. Second 
gnathopod (Figure 5): larger than Gl, the carpus 
posteriorly lobate and pubescent, bearing long, 
strong, apically curved setae, propodus ovate, 
palm strongly acute, dactyl extending beyond the 
corner defined by 2 long 'hadziid' setae and a 
slender seta laterally, and single lateral and medial 
bifid setae, palm bearing few short, simple setae, 
dactyl without a nail, bearing 7 recumbent, inner 
tooth spines and 5 sub-marginal, posterior, 
accessory setae as well as a single small seta on thq 
medial face at M0.6. Two moderate length spines 
arise from the propodus at the base of the dactyl. 
Coxal plate similar to Gl, bearing 1 ventral, 3 
antero-ventral, and 1 antero-facial setae. Pcreopodh 
(Figure 5). Coxae 3-4 each with 3 ventral setae, r\c\ 
posterior setae, coxa 4 not excavate posteriorly, the> 
posterior margins of article 6 of P3—4 with few 
armaments; formulae S-S and S-S-S, P3-4 subequal, 
smaller than P5-(7). Coxa 5 bearing 1 anterov 
ventral seta, and coxae 5-7 bearing single setae or\ 
their posterior margins, article 2 moderately 
expanded bearing a small lobe on P5-6. Dactyls of 
P3—4 long and slender, bearing 2 distal accessory 
spinules; ie. 2 additional spinules as well as ai\ 
outer basal penicillate setule. Gills of coxae 2-6 
each with a large, single, flask shaped gill. Gill 5-6 
largest. Epimera (Figure 6) 1-3 without posterior 
tooth, posteriorly convex to straight, smooth, 
without facial setae. E3 bearing a single anteros 
ventral seta, El-2 each with a single posterior seta, 
Urosome poorly armed dorsally. Pleon. Pleonites 1-. 
6 with few small dorsal setae , dorso-lateral setae 
largely absent, pleonite 4 with a single, small disto^ 
ventral spine at the base of uropod 1 . Pleopoda 
(Figure 3): similar, retinacula 2 per pleopod. 
without accessory retinacula, peduncles without 
setae, rami extending sub-equally, without bifid or 
'diamond head' setae; all setae similar, plumose, 
Uropods. (Figure 3). First uropod peduncle length 
greater than length of inner ramus; medial and 
lateral margins each bearing 2 setae, single apico-- 
lateral and apico-medial spines, and a moderate 
baso-facial spine. Rami unequal; inner ramus 
longer (50:46), lateral ramus without setae except 
an apical group of 5, the medial ramus bearing a 
single medial seta and an apical group of 5 setae, 
the medial margins of both rami bearing a row of 
fine pubescence. Second uropod peduncle sub-equal 
in length to the shorter, outer ramus, without setae 
except for single lateral and medial apical setae. 
Inner ramus longer than outer (41:35), outer ramus 
bearing a lateral row of 2 setae at M0.6 and M0.7, 
and 4 terminal spines, the inner ramus with a 
single dorso-medial spine, and 5 terminal spines. 
Medial margins of both rami bearing small, 
pubescent setae. Third uropod magniramous, 
dispariramous. Peduncle much shorter than outer 
ramus (30:87), with a single small baso-medial seta, 
without any apical setae. Outer ramus of 2 articles, 
proximal article bearing 5 lateral, 2 plumose and 1 
naked disto-medial marginal setae, and 1 and 2 
apical spines respectively. The distal article short

setules. Inner ramus of one article, lanceolate, 
shorter than the outer ramus (80:87), marginal 
setae discontinuous basally on the lateral margin, 3 
lateral and 6 medial setae, the baso-medial seta 
more robust, and a single tiny sub-apical, slightly
