deep reddish brown; sculpturing as typical in members 
of the genus; body 4.45 mm. long. Carapace as in the 
genus ; anterior eye of each side narrowly elliptical and 
separated from the posterior eye by about twice the lesser 
diameter of the anterior eye ; a heavily sclerotized keel or 
ridge between the eyes, reaching its greatest development 
at the anterior border of the posterior eye ; anterior eye 
removed from the anterior carapacal margin by a dis- 
tance equal to four or five times the diameter of the pos- 
terior eye ; lateral margins of carapace gently and evenly 
convex ; posterior margin with six marginal setae ; length 
of carapace 1.35 mm. ; greatest width along the posterior 
margin and equal to 1.5 mm. ; ocular breadth about 0.8 
mm. Tergites 2 through 10 divided; tergites 4 through 
10 with each tergal half marked by a centrally located 
and more deeply pigmented spot; setae subclavate, ter- 
minally truncate but not much widened ; tergites 1 and 2 
with eight setae; other tergites with 10 to 16 setae. Ster- 
nites 5 through 10 marked by pigmented spots similar to 
those of the tergites; division of some sternites weakly 
indicated; sternite 4 with eight marginal setae; setae of 
other sternites ranging from 10 to 14; setae of anterior 
sternites acuminate, some setae of posterior sternites 
weakly subclavate. Abdomen stout; 3.1 mm. long, about 
2.5 mm. wide. 
Chelicera as usual in members of the genus; longest 
blade of flagellum with three or four slender and long 
dentations placed a little distal to the midpoint; length

0.21-0.22 mm. ; length of movable finger about 0.26 mm. 
Fixed finger with relatively narrow lamina exterior ; four 
retroconical teeth on the distal half of the inner finger 
margin, two smaller denticles on the inner margin of the 
apical tooth. Movable finger little curved ; subapical lobe 
poorly developed, located approximate to the apical 
tooth; apical tooth little sclerotic; galea gently curved, 
simple, stout, terminally rounded and blunt, with con- 
spicuous gland ducts passing from the base to the tip ; 
serrula exterior of 19 ligulate plates ; galeal seta not 
reaching nearly to the tip of the galea.
