Paratypes 
Australia: Western Australia: 1 tJ (WAM 18-95); 
1 d (WAM 19-95); 2 2, 2 d (author's collection); 
all from type locality and date. 
Diagnosis 
Female 530-560 pm, male 427-458 pm. 
Integument uniformly and delicately punctate. 
Female and male with four and three free thoracic 
somites respectively. Female A1 five-segmented, 
male A1 seven-segmented. Mx2 slender, its basis 
seven times longer than wide. Maxillipedal 
endopod widened; basal appendage cylindrical, 
heavily sclerotised; tongue-like appendage slender. 
Maxillipedal claw with two rows of conspicuous 
teeth. Pl-exp slightly smaller than endopod. P4- 
enp with a single seta. Female P5 with 
baseoendopod and exopod almost completely 
fused. Male P5 undivided. 
Description 
Female 
Length 530 (holotype. Figure 1) to 560 pm, height 
360 (holotype) to 365 pm. Colour of ethanol- 
preserved specimens light-brown. Integument of 
most of cephalothorax, as well as that of posterior 
somites, delicately punctate; in a 20-25 pm wide 
ventral portion fine punctation of cephalosome 
replaced by epicuticular droplets (Figure 2), which 
are arranged like beads on a string. Integument of 
lateral flanks of genital somite delicately reticulate 
rather than punctate. All somites with pores 
(Figure 1); pores generally opening at outer surface 
of somites; row of four ventralmost pores on 
cephalosome opening at inner flank of 
cephalosomal shield. 
Cephalothorax 295 pm long. Ventral margin of 
cephalosome with about eight 4—5 pm long setulae; 
each setula with 10-15 pm long canaliculus 
penetrating the tegument. Similar setulae present 
also on cephalic shield and on posterior somites. 
Cephalothorax with two pairs of setae, one lateral, 
the other dorsal. Cephalothorax with internal 
sclerite extending dorsally for 90 pm. Succeeding 
four free thoracic somites 65, 90, 127, and 68 pm 
long. Third somite almost twice length of second 
and fourth free somite. First to third somite with 
one, two, and two setae, respectively. Delicate 
setulae, similar to those present along ventral 
margin of cephalosome, inserted 10-20 pm 
removed from ventral margin of epimera. Genital 
somite 74 pm long. Enlarged egg-reservoir with 
posteriormost edge extending slightly beyond anal 
cone; ventral edge truncate. Postgenital somites 
small, not fused with genital somite. 
A1 (Figure 3) five-segmented; segments 55, 57, 
38, 22, and 30 pm long. Number of setae: 1,11, 9, 4 
+ Ae, 16 + Ae. Seta on Al-1 as long as segment 1. 
Aesthetasc on Al-4 90 pm (holotype) to 110 pm 
long, and 4 pm wide, that on Al-5 50 pm long, 1-2 
pm wide. 
Exopod (Figures 4, 5) of A2 small, two- 
segmented; 11 pm long basal segment with one 
seta; 2 pm long apical segment with two setae, both 
longer than exopod, one of the setae distinctly 
serrate. Basal and apical segment of endopod 40 
and 30 pm long. Basal segment with row of delicate 
filaments along posterior (ventral) margin, and a 
pore, but no seta, on anterior (dorsal) margin at 
0.55 relative to length of segment. Apical segment 
posteriorly with three contiguous clusters of 
filaments, and anteriorly with two slightly plumose 
setae at 0.4 and 0.6 respectively. With six apical 
setae, two of which are claw-like, 25 and 60 pm 
long; remaining setae slender. 
Mandibular gnathobase (Figures 6, 7, 10) with 
stout, serrate and two to three crowned teeth, and 
a long seta. Palp (Figure 8) undivided, flattened 
and ending with five bilaterally plumose setae. 
Edges of palp lined with filaments. 
Mxl as in male (Figure 11) with wide, flattened 
arthrite armed with five wide, apically serrate 
spines and three setae. Seta of coxa bearing two 
rows of filaments and extending to apex of basis. 
Flattened basis (Figure 9) with row of delicate 
filaments; four terminal setae with filaments. Two 
endopodal setae present, the longer one almost 
twice as long as the other seta and lined with 
filaments. Exopod with three setae, one of which is 
short, the two other subequal in length; all three 
setae with bilateral filaments. 
Mx2 as in male (Figure 12) with two slender 
segments. Basal segment (syncoxa) 44 pm long and 
12 pm wide, its posterior margin bare. Basal endite 
with three, middle endite with two plumose setae. 
Two setae on distal endite 2.0 and 2.5 times longer 
than endite and bearing filaments. Basis of Mx2 
very slender, 42 pm long and 6 pm wide, with 
scattered, delicate filaments. Basis ending with 
setiform claw and five plumose setae. 
Maxilliped subchelate, inserted on small 
pedestal. Maxillipedal basis (Figure 13) slender, 
130 pm long. Surface of segment smooth. No 
filaments around medial fovea (fovea from 
tendon). Endopodal segment widened (Figures 14, 
15); with median tooth-like projection, flattened 
median tine, four small lateral denticles (Figure 14), 
and about 35 medial denticles (Figure 15). Heavily 
sclerotised cylindrical appendage with spinose 
apex and short setula-like aesthetasc. Stalked, 
tongue-like appendage slender, with spinose edge 
and short setula. Maxillipedal claw as long as
