mm ; metatarsus, 0.78 mm ; tarsus, 0.50 mm. Second patella and tibia, 
0.71 mm; third, 0.52 mm; fourth, 0.91 mm. 
Diagnosis. The epigynum, which has a dark patch in a light trans- 
versely folded area (Fig. 21), separates this species from C. alboma- 
culata. The sacs of the internal genitalia (Fig. 20) are more complex 
in shape than in related species.

rings on middle and distal ends of segments. Abdomen whitish with 
some black patches (Fig. 76). Chelicerae with two anterior teeth. 
Anterior median eyes one and one-fourth diameters apart, three- 
fourths from laterals. Posterior median eyes slightly more than a diam- 
eter apart, one diameter from laterals. Eyes of male smaller and 
slightly farther apart. Legs very long. Total length of female 4.5 mm. 
Carapace 1.3 mm long, 1.0 mm wide. First femur, 4.9 mm; patella 
and tibia, 4.5 mm; metatarsus, 4.9 mm; tarsus 1.4 mm. Second patella 
and tibia, 2.3 mm; third, 1.2 mm; fourth, 2.0 mm. Total length of 
male 3.0 mm. Carapace, 1.6 mm long. Second patella and tibia, 2.7 
mm; third, 1.3 mm; fourth, 2.3 mm. 
Diagnosis. The coiled rim of the epigynum (Fig. 78), the coiled 
ducts (Fig. 77) and the long embolus and narrow cymbium (Figs. 22, 
23) distinguish this species from C. volcanensis.
