fewer than ten setae. Cuticle seemingly devoid 
of striae or other markings except for the 
underlying reticular layer. 
Coxae I and II (Fig. 122) with about 50 
and 60 setae respectively, plus 7 to 10 setae 
on the pars medialis. All setae smooth. No 
supracoxal setae; coxal ring I open dorsally, 
II closed dorsally (Fig. 107b). Coxae III and 
IV with 70 to 75 setae each, coxal ring of each 
complete dorsally (Fig. 107a). Cuticle of all 
coxae faintly punctate. Intercoxal area be- 
tween I and II with 65 to 70 smooth slender 
setae, each borne on a small sclerite; a narrow 
band of cuticle behind coxae I and II devoid 
of setae. No sclerotized plates in the mem- 
branous area between coxae II and III. Ven- 
tral body setae like those on dorsum, except 
that the sclerites are not so prominently 
raised. Genital sclerites (Fig. Ill) bearing 35 
to 45 smooth slender setae; paragenital scler- 
ites narrower than genital sclerites but bearing 
43 to 50 setae of the same form as those on 
the genital sclerites (three specimens) . Genital 
acetabula well developed, the second pair the 
smallest. Anal sclerites (Fig. 105) quite vari- 
able, with from 11 to 19 setae arranged in a 
single to double row; setae similar to those 
on genital sclerites. 
Base of gnathosoma and rostrum bearing 
about 45 setae on each side, supracoxal setae 
absent. Rostrum relatively short and broad; 
tip of rostrum (Fig. 106) with two pairs of 
specialized setae, presumably the protoros- 
trals and tritorostrals. Velum small, circular, 
and oriented in an anterior direction (Fig. 
125). Chelicerae as shown in Figure 108. Tro- 
chanter of palp (Fig. 127) devoid of setae; 
medial wall fenestrated. Tibia with a heavy 
spiniform seta at 0.58^ and a second one at 
the end of the segment. A series of three very 
sharp spines dorsally, in basal third of tibia 
(Fig. 126). Tarsus with a large eupathid borne 
on a prominent tubercle at 0.61 d and a group 
of two large and two small eupathids near 
the tip of the segment (Fig. 124). A single 
solenidion at 0.57/?. Normal setae of palp 
smooth and tapering. 
Trochanters I and II with about 8 setae 
dorsally, three with about 10 setae dorsally, 
and four with 20 to 25 setae, all these setae 
smooth to faintly hemipectinate. All basi- 
femora lacking specialized setae, normal setae 
on dorsal portions of segment smooth to 
faintly hemipectinate, those on ventral half 
of segment usually very fine and smooth. 
Chaetotaxy of legs approximately as shown 
in table (s = solenidia, e = eupathidia, f = 
famulus, v = vestigial setae, c = companion 
setae, n = normal setae, m = many). 
Vestigial setae absent from all legs. Tarsus 
I with famulus elongate, erect, its alveolus 
located on a prominent tubercle at 0.31 pd 
(Fig. 123). Solenidionx actually smaller than 
the corresponding seta on tarsus I of the larva, 
inserted at 0.52^ at the origin of the claw 
fossa. A group of five thick, stout S 2 extending 
from 0.57 to 0.80/?. These are generally 
slightly smaller than the corresponding setae 
on tarsus II but are the same general form and 
are internally annulate. Eupathidia very nu- 
merous, extending from 0.26^ to 0.13^, or in 
other words around nearly the entire peri- 
phery of the tarsus I. Basal portion of tarsus 
I from about 0.30z? to 0.52 d, extremely rough, 
provided with sharp, truncate tubercles. These 
tubercles bear the alveoli of a number of types 
of setae including the famulus, eupathidia, 
solenidia 4 , and bihemipectinate normal setae. 
The normal setae on all segments of the legs 
are smooth or very nearly so, with the excep- 
tion of those of tarsus I. Tarsus II with a 
clavate s 2 at 0.49 to 0.50<^, and a spikelike
