areolae; the ventral plates being rather smooth save 
of the demarcated areolae with modified rosette 
pores. Species belonging to this group are A. 
chelipes Bartsch, A. delicatula Newell, A. estnarina 
Newell, A. mccaitii Newell, A. papillata Bartsch, and 
A. pugio (Trouessart). A. delicatula lacks the 
conspicuous porose areolae on AE characterizing 
the other species, but the chaetotaxy of the palps 
and legs agrees with that known of the pugio 
group. 
A. elaborata is distinguished from all other 
Agauopsis on the basis of its PD with the internal, 
sinuose sclerites, its deeply excavated median 
portion filled with protruding epicuticular 
filaments, and its enlarged ds-4, ds-5 and ds-6.

Description 
Female 
Idiosoma 297-310 pm long, 200-223 pm wide, 
holotype 310 pm long, 223 pm wide. Dorsal plates 
with distinctly raised areolae. Within these areolae 
(Figure 50) integument thicker than in surrounding 
plate, and deeper layers of integument bear 
subquadrangular alveoli, 2-3 pm long, 3-5 pm 
wide. Alveoli separated from each other by 
cuticular bars. Each alveolus with four to seven, 
rarely up to nine canaliculi piercing the integument 
and opening with small pores at the surface. Areas 
between raised costae with pits which are more or 
less distinctly arranged within polygons. 
Dorsal portion of anterior epimeral plate (Figure 
51) with 25 pm wide frontal process; that process 
with minute median spine and pair of 
approximately 20 pm long ridges. Length of 
anterior plate 115 pm (from tip of spine to the 
somewhat excavate posterior margin), width 97 
pm. AD with pair of raised costae, major parts of 
these costae an alveolus wide, posterior portion of 
costae one to two alveoli wide. OC 78 pm long, 52 
pm wide, with two distinct corneae and a 
transverse, raised porose areola. Gland pore and 
pore canaliculus almost adjacent in lateral margin 
of the plates. PD 165 pm long, 120 pm wide. 
Anterior margin rounded. Pair of longitudinal 
costae not joined with transverse posterior bar. 
Anterior and middle portion of costae one alveolus 
wide, posterior portion two alveoli wide. 
Transverse bar two alveoli wide. Pair of gland 
pores present lateral to posterior portion of costae. 
Setae ds-1 inserted on level with insertions of leg I, 
setae ds-2 on 5 pm wide sclerite within striated 
integument between AD and OC, ds-3 not seen, 
ds-4 and ds-5 on PD level with insertions of legs III 
and IV, ds-6 posterior to transverse bar. 
Ventral plates (Figure 52) with demarcated 
porose polygons, remainder of plates delicately 
pitted. Each porose polygon with 7-12 canaliculi 
(Figure 53). AE 100 pm long, 193 pm wide. 
Epimeral processes triangular, pointed. Area 
medial to insertions of legs II raised. Porose areolae 
garland-like, arranged as illustrated. GA 130 pm 
long, 98 pm wide, with two pairs of porose areolae. 
GO 55 pm long, 16 pm wide. Distance from 
anterior margin of GO to that of GA almost same 
as length of GO. Subgenital setae lacking. Anterior 
pair of perigenital setae level with anterior margin 
of GO. Ovipositor short, when at rest not reaching 
end of GO. Spermatheca 7 pm in diameter. 
Gnathosoma 87 pm long. Gnathosomal base with 
pair of demarcated porose areolae (Figure 54). 
Tectum truncate (Figure 55). Rostrum 35 pm long. 
Palps extending somewhat beyond tip of rostrum. 
P-2 with long dorsal seta. P-3 4 pm long, its medial 
spine longer than P-3. P-4 10 pm long (apical spur¬ 
like setae included); with two basal setae, and 
apically with minute seta and two spurs (Figure 
56). 
Dorsal and medial flanks of telofemora (Figures 
57 - 60) with wide reticulate sculpturing, lateral 
flanks with delicate reticulum. Telofemora II-IV 
with ventrolateral lamellae; articular lamellae 
lacking. Membranes of claw fossae reduced to 
small lamellae. Tibiae of legs I, II and IV shorter 
than telofemora of these legs, tibia III about as long 
as telofemur III. Tarsi of legs III and IV longer than 
tibiae. Leg chaetotaxy, from trochanter to tarsus 
(solenidion omitted): leg I, 1, 2, 8, 5, 8, 10; leg 11, 1, 
2, 5, 5, 5, 5; leg III, 1, 2, 3, 3, 5, 4; leg IV, 0, 2, 3, 3, 5, 
4. Two ventral spines on telofemur I 11 and 18 pm 
long, ventromedial spine 18 pm long; ventral spine 
on genu I 7 pm and ventromedial spine 15 pm 
long; ventral spine on tibia I 10 pm and the two 
ventromedial ones 16 and 11 pm long; 
ventromedial spine on tarsus I 10 pm long. Spines 
delicately pectinate. Tibia II (Figure 61) with a 
pectinate ventral and a short, wide and bipectinate 
ventromedial spine. Tibiae III and IV with pair of 
tapering bristles, the ventrolateral one distinctly 
longer than the ventromedial one. Tarsus I (Figure 
62) with doubled pas; 5 pm long solenidion 
between dorsolateral seta and lamella with vestiges 
of famulus. Tarsus II (Figure 61) with three dorsal 
seta, a 6 pm long solenidion behind narrow medial
