Psyche 
granular and marked by netlike lines; anterior margin 
bilobed, lateral margins weakly convex; eyes large, the 
eyes of one side separated by less than one ocular diame- 
ter; eyes removed from the anterior carapacal margin 
by between two and three ocular diameters ; transverse 
furrows weakly developed; setae scattered, fairly numer- 
ous ; length of carapace 1.28 mm., greatest width pos- 
teriorly and equal to 1.1 mm., ocular width 0.7 mm. Ab- 
domen oval-elongate, length 3.1 mm., width about 1.9 mm. 
Tergites 2 to 10 divided; surface sculptured as on the 
carapace ; brown in color ; setae weak and short ; first ter- 
gite with 10 setae, lialf-tergites of central and posterior 
part of body with six or seven setae along the posterior 
margin and two or three setae along the lateral margin; 
intertergal membranes and median membranes between 
lialf-tergites continuous, wide, and marked by wavy st na- 
tions. Sternites 4 to 10 divided; very lightly pigmented, 
especially anteriorly; sculpturing scalelike or netlike 
and much more weakly developed than on the tergites; 
setae short, fine, more or less similar in number and ar- 
rangement to those of the tergites ; intersternal mem- 
branes like those of the tergites. Pleural membranes 
wide, marked by rugose or papillose striations. Stig- 
mata placed entirely in the pleural membranes and not 
on the sclerotic sternal halves. 
Chelicera fairly sout, yellowish brown in color; length 
0.36 mm., width of base about 0.215 mm. Base quadrate ; 
inner margin with a deep sinuation between the base and 
the fixed finger ; setae is, Is, and sb located on the promixal 
half of the fixed finger; dorsal surface of base weakly 
sculptured by netlike lines. Flagellum with three stout 
and much flattened blades ; the posterior blade two-thirds 
as long as the anterior one, the central blade intermediate 
in length; each blade denticulate, with the teeth long, 
slender, irregular in distribution and length, and confined 
to the distal two-thirds of each blade. Fixed finger very 
convex, with well-rounded lamina exterior; apical tooth 
very dark brown and sclerotic, with two small denticles 
on the inner surface ; inner margin of finger with one or 
two stout, sclerotic, retroconical distal teeth followed
