other by slightly less than their radius and from PLE by their 
radius; ALE and PLE contiguous; long diameters always used for 
measurements; all eyes on a forward projection of the cephalic region 
of the carapace. Height of clypeus equal to nearly three times the 
diameter of AME. Six robust spines are placed above AME (Fig. 2) . 
Chelicerae: moderately robust, vertical, slightly divergent; fang 
normal, evenly curved; fang groove, as observed in dissested speci- 
men, has a tooth of moderate size on each margin near base of fang 
and a pair of small teeth on each margin near the medial end of 
fang groove; on the posterior surface of each chelicera. there is a 
cluster of small cusps a little above the middle; some variations in 
respect to teeth have been noted among the numerous specimens 
available for comparison and even between right and left sides in 
the same specimen. Maxillae: nearly three-fourths as broad as long; 
only slightly convergent. Lip : short, broad, only about one-third 
as long as maxillae. Sternum: very convex; scutiform; about as 
broad as long; bluntly terminated between fourth coxae which are 
separated by their width. Legs: 1243 in order of length; in general 
long and slender; with few slender spines; distinctive spines of first 
patella and tibia as shown in Figure 3. Palp: all segments except 
tarsus without special modifications; tarsus complicated (Figs. 4-6). 
Abdomen : general form as shown in Figure 7 ; without special 
modifications. Color in alcohol: carapace brownish with variations; 
lateral sides of thoracic region with irregular, darker, radiating 
bands; a somewhat irregular, central V-shaped darker area extends 
from the beginning of the posterior declivity toward the ocular 
region. Chelicerae, maxillae, lip and sternum brown with small 
irregular dots. Legs yellowish with darker areas. Abdomen: with 
a highly decorative color pattern; the anterior two thirds of the 
dorsal surface is yellowish with several irregular white spots; the 
posterior third of the dorsal surface is darker brownish surrounded 
by numerous irregular white inter-connected spots; ventro-laterally 
on each side there is an irregular white band composed of several 
iregular white spots; the venter is brown with a pair of small light 
spots somewhat behind the middle. The color pattern is difficult to 
describe accurately and, moreover, much variation has been noted 
among the numerous specimens available for comparison. 
Female. Total length 1.58 mm. Carapace 0.57 mm long; about 
O.53 mm wide; about 0.33 mm tall; general form essentially as in 
male; ocular region less prominent than in male. Eyes: ratio of 
eyes AME : ALE : PME : PLE = 5 : 7 : 8 : 6.5 ; AME separated 
from one another by a little less than their radius and from ALE by
