sixth pairs of setae (adanal setae) in dorsal position. 
AE with three pairs of ventral setae and, generally, 
one pair of epimeral pores. Female typically with 
three pairs of pgs, male with 20-100 pgs close 
around the GO plus 0, one or two pairs of outlying 
setae. Gnathosomal base rectangular; rostrum 
parallel-sided. Basal pair of maxillary setae 
generally on base of gnathosoma, apical pair on 
rostrum. Palps four-segmented, attached laterally 
to base of gnathosoma. P-2 with one (rarely two) 
dorsal seta, P-3 with median spine or bristle. Leg I 
much wider than succeeding legs, bearing 
conspicuous spines. Tarsus I with three dorsal 
setae, dorsolateral solenidion, ventromedial spine, 
two unpaired ventral setae, and lateral and medial 
eupathid parambulacral setae. Tarsus II with 
solenidion dorsomedial in position. Paired claws 
on tarsus I smaller than those on succeeding tarsi. 
One larval and two nymphal stages.

Description 
Female 
Idiosoma 381 pm long, 230 pm wide. Most of 
dorsal plates with rather uniform porosity (Figure 
1) which is made up by modified rosette pores. 
Each rosette pore typically with 6-9 canaliculi 
arranged along the borders of polygons; canaliculi 
running curved through the integument (Figure 2) 
and almost meeting in deeper layers. In centre of 
each polygon, surface of plate with very shallow 
central pit. 
Anterior idiosoma (Figure 3) with rounded, 
dome-like frontal protuberance. AD anteriorly 
fused with dorsal portion of anterior epimeral 
plate; length of that plate, from posterior truncate 
margin to tip of frontal protuberance, 160 pm, 
width 130 pm. Two 25—40 pm wide porose costae 
joined posteriorly. Median area of plate with 
delicate pits, costae with canaliculi. Lateral 
portions of plate distinctly demarcated from 
abruptly raised porose area and densely studded 
with minute cuticular denticles. A pair of very 
delicate gland pores anterolateral to porose costae. 
OC 80 pm long, 32 pm wide, its posterior portion 
tapering. Comeae not seen. Anterior portion of OC 
with slightly raised porose areola, and with small 
gland pore and pore canaliculus in lateral margin. 
PD 202 pm long, 145 pm wide; its anterior margin 
truncate. Anterior portion and major parts of 
raised wide median area of PD with very 
prominent porosity, a posterior oblong area 
without canaliculi. Lateral portion of PD beset with 
cuticular denticles. Pair of gland pores on level 
with insertion of leg IV. AD with setae ds-1 and 
ds-2, PD with setae ds-4, ds-5 and ds-6. 
Marginal areas of ventral plates with small 
canaliculi, large ventral areas with delicate pycnic 
rosette pores; anterior AE and small transverse 
areas on GA with cuticular denticles. AE 132 pm 
long, 221 pm wide (Figure 4); posterior margin 
slightly concave. Epimeral processes I elongate; 
processes of epimera II lamellar. AE with three 
ventral setae. Epimeral pores not seen. PE with one 
dorsal and three ventral setae. GA 167 pm long, 
145 pm wide. GO 65 pm long, 30 pm wide. Interval 
between anterior margin of GA and that of GO 
same as length of GO. Three pairs of pgs inserted 
as illustrated. Subgenital setae lacking. 
Gnathosoma (Figure 5) 91 pm long, 66 pm wide. 
Gnathosomal base ventrally with small scattered 
pores, dorsally with delicate cuticular denticles. 
Rostrum and palps shorter than base of 
gnathosoma. Basal pair of maxillary setae on base 
of gnathosoma, the other pair inserted in apical 
third of rostrum. Chelicera 95 pm long. Dorsal seta 
on P-2 as long as length of that segment. Apical 
segments of right and left palp somewhat 
dissimilar in size, P-3 3 and 4 pm long and 6 pm 
wide, P-4 6 and 7 pm long and 4 pm wide. Medial 
7 pm long spine of P-3 with truncate tip (Figure 6). 
P-4 with two setae and two apical spurs; length of 
two latter almost same as that of P-4. 
Leg I (Figure 7) very wide; lateral flank of 
telofemur with conspicuous canaliculi, medial 
flank with reticulate pattern and delicate cuticular 
denticles. Genu, tibia and tarsus I laterally with 
cuticular denticles, dorsally with pits and medially 
again with denticles. Telofemur and tibia I each 
with large lateral articular lamella, 1-3 also with 
about 6 pm high dorsal lamella. Telofemora II-IV 
very wide due to long, 20 pm high ventrolateral 
lamella, ventral protuberance and long, 11 pm high 
dorsal lamella; lateral flanks (Figure 8) with 
canaliculi, medial flanks with less conspicuous 
pores. Tibiae II-IV (Figures 9-11) with medial and 
lateral articular lamellae. Tarsus 1 shorter than tibia 
I; membranes of claw fossa (Figure 12) present 
though short. Tarsi II-IV each with ventral lamella, 
giving the tarsi a conspicuous truncate outline; 
dorsal and dorsolateral flank with cuticular 
denticles which often are tapering and filament- 
like. Membranes of claw fossae small. Leg 
chaetotaxy from trochanter to tarsus (solenidia 
excluded): leg I, 1, 2, 7, 5, 8, 8; leg II, 1, 2, 5, 4, 5, 5; 
leg III, 1, 2, 3, 3, 5, 4; leg IV, 0, 2, 3, 3, 5, 4. Leg I 
with wide, apically truncate and slightly dentate 
spines; telofemur with two ventral spines, 18 and 
30 pm long, and one ventromedial spine; genu with
