posteriorly. Posterior lateral corner of second pedigerous segment 
produced posteriorly into curved, acutely pointed process. Third 
pedigerous segment with median dorsal line of sclerotization. 
Urosome about three-tenths as long as prosome; posterior margins of 
segments serrate; serrations coarsest on median dorsal part of third 
segment. Caudal rami about a fifth longer than wide, without 
hairs on inner margins. Next-to-innermost caudal seta with short 
hairs on both margins of proximal part. Proximal part of second- 
from-innermost seta with short hairs on inner margin and barbs on 
outer margin. 
Antenna 1 reaching nearly to margin of first pedigerous segment, 
composed of 16 segments. Antenna 2 with 1 seta on basipod; exopod 
3-segmented; setation as shown in figure 7a. Basipod of mandibular 
palp with 2 setae; endopod segment 1 with 4 setae. Manilla 1 with 
5 setae on second basal segment; endopod with 2 groups of 3 setae on 
medial margin; exopod with 11 setae. Basal segment of maxilliped 
with 2 rows of surface spinules, 1 proximal to middle group of 3 setae, 
the others slightly set in from proximal margin of distal lobe. 
Exopod segment 2 of leg 1 produced at outer distal corner into 
medially curved hook; distal outer seta of exopod segment 3 longer 
than proximal outer seta. Leg 1 with a few spinules on first basipod. 
Legs 2-4 with patterns of surface spinules shown in figure 86-d; 
exopod segment 2 and proximal part of segment 3 of leg 2 with serrate 
outer margins; distal margins of exopod and endopod segment 1 of 
leg 3 finely serrate. 
Connecting piece of leg 5 with nearly straight distal margin. 
Exopod segments 1 and 2 with stout outer setae; segments 2 and 3 
with 1 inner seta. Endopod unisegmental, pyriform, bearing 3 rows 
of surface spinules; medial margin with small subterminal notch and 
larger setiferous notch at about a third the distance from proximal 
end. First basipod bearing a row of spinules parallel with and just 
proximal to distal margin. Second basipod with rounded bulge 
bearing row of spinules; medial distal corner produced into ensiform 
process slightly more than half the length of endopod. 
Maur: More slender than female; total length about 0.72 mm. 
Rostrum as large as in female, not articulated. Caudal setae as in 
female. Right antenna 1 17-segmented; anterior margin of antepenul- 
timate segment produced distally into triangular process; segment 14 
with heavy spine. Right first basipod of leg 5 with row of surface 
spinules near distal margin. Right second basipod with curved row 
of spinules near origin of endopod. Right endopod more than twice 
as long as wide, notched near apex. Left second basipod with several 
rows of surface spinules. Inner membranous lobe of left exopod seg- 
ment 2 trapezoidal, with slender linear process on inner margin; outer
