tergites and the anal operculum. Eye tubercle slightly removed from 
the anterior margin of the cephalothorax (Fig. 20). Eyes and 
corneal lenses absent. Abdominal scutum with five dorsal areas, the 
first without a median line, the boundaries of which are parallel 
to one another, but very poorly defined. Ventral surface and coxae 
with scattered thin hairs. Spiracles clearly visible. Hair-tipped 
tubercles (arranged in rows) are present on the anterior and posterior 
margins of coxa III. In the remaining coxae, there are some similar 
tubercles, but not arranged in rows. The endite of the second coxa 
lacks a ventral projection (Figs. 21, 22). 
Chelicera has a few scattered, long hairs. Proximal article 
slender at the base and enlarged dorsally in the distal two-thirds. 
Distal article somewhat enlarged laterally at the base and with a 
large frontal elevation tipped with a rounded tooth (Fig. 23). 
Palpus almost twice as long as the body. Armed in ventrolateral 
view as in Fig. 23. Dorsally unarmed except for rows of long hairs. 
Tarsal claw long and curved. 
Legs extremely long and slender, clothed with hairs and finely 
granulate. Metatarsi divided into astragali and calcanea. Fine granu- 
lations on legs terminate abruptly at calcaneus of metatarsus. First 
and fourth legs have an extremely long first tarsal article, other 
legs have first tarsal article longer than the remaining ones (Fig. 25). 
Fourth metatarsus with a very long hair-tipped tubercle situated 
at the apex (Fig. 25). First metatarsus somewhat enlarged at the 
base. Tarsal formula: 3, 5, 5, 5. Distitarsus of first tarsus with 
two articles, second with four. 
Body concolorous, pale yellow-orange, with venter somewhat 
lighter than dorsum. Appendages the same color as the body, but 
tarsus and metatarsus lighter yellowish. 
Penis long and slender, in lateral view as shown in Fig. 26. 
Total length, 0.85 mm. Morphologically similar to that of C . good- 
night! . 
Female. Measurements of entire body and appendages are the 
same as of male, except the abdomen is somewhat wider. Tarsal 
formula as in male. Similar in appearance to males, but chelicera 
without the large frontal elevation tipped with a rounded tooth. 
Fourth metatarsus without hair-tipped tubercle on the apex, and 
first metatarsus not enlarged at the base. Ovipositor short and 
thick. Total length, 0.50 mm. Very similar to the former species.
