Ratio of eyes AME : ALE : PME : PLE = nearly 8 : 11.5 : 8.5 
: 10 (irregularities in outlines quite noticeable). AME separated 
from one another by nearly three-fourths of their diameter and 
separated from ALE by nearly 1.5 times their diameter. Height of 
clypeus nearly equal to diameter of AME. PME separated from 
one another by slightly less than twice their diameter and separated 
from PLE by nearly 2.25 times their diameter. Lateral eyes separ- 
ated from one another by 1.5 times the diameter of PLE. Central 
ocular quadrangle wider behind than in front in ratio of nearly 
16 : 11 ; wider behind than long in ratio of 32 : 23. Chelicerae: 
robust; with well developed basal boss; surface granulose; moder- 
ately geniculate near base; lateral margins somewhat swollen distal 
to boss; without observed keels; fang regularly curved; fang groove 
with three teeth along promargin and two along retromargin ; 
scopula moderately well developed. Maxillae: typical of males of 
the genus in general; outer distal corner obtusely rounded (Fig. 23) ; 
longer than lip in ratio of nearly 20 : 13. Lip: typical of the genus 
in general; longer than wide at base in ratio of nearly 14 : 11. 
Sternum: moderately convex; longer than wide in ratio of nearly 
77 : 60; with lateral extensions as usual in the gen^s; anterior 
border trilobed and essentially as represented in Figure 24; surface 
finely granulose and with many short, stiff hairs; posterior end 
bluntly rounded just opposite bases of fourth coxae which are separ- 
ated by nearly half their width. Legs: 1243 in order of length; first 
legs most robust of the four pairs; no true spines observed; tricho- 
bothria observed on several segments; with few spiniform bristles; 
first leg with several dozen cusps on ventral surfaces of tibia, about 
half as many on the ventral surface of the metatarsus and only a 
small number on the tarsus; second legs with a reduced number of 
cusps on the same segments; third metatarsus with a fairly well 
developed ventral distal brush. Palp: essential features shown in 
Figures 25-26; only tibia and tarsus with significant modifications; 
tibia with a short, distal, retrolateral apophysis; bulb with a terminal, 
conical embolus tipped at an angle ; spiniform bristles somewhat 
conspicuous on some segments. Abdomen: broad ovoid; with no 
indication of a dorsal scutum; with very little chitinization in 
epigastric region. Color in alcohol: cephalothorax, legs and mouth 
parts nearly typical of the genus; abdomen with a brownish gray 
dorsum with several very narrow, lighter, irregular, transverse lines 
near posterior end; venter somewhat lighter, yellowish.
