(Fig. 7). PME continguous to one another for nearly one-third 
of their circumference and subcontiguous to PLE. Height of clypeus 
apparently equal to nearly one-fourth of the long axis of ALE but 
transparency makes accurate measurement difficult. Chelicerae: 
parallel; apparently without special modifications. Maxillae and lip: 
apparently typical of the genus. Sternum: convex; scutiform; with 
a deep excavation at junction with lip; only slightly longer than 
wide between second coxae where it is widest but nearly as wide 
between first coxae; only slightly lobed and not noticeably grooved; 
with a sparse coating of stiff bristles; squarely truncated between 
fourth coxae which are separated by eight-fifths of their width; 
second and third coxae nearly globose; first and second coxae some- 
what more elongated. Legs: 4123 in order of length; slender, 
transparent spines are present especially on the third and fourth legs 
but these could easily be regarded as spiniform bristles. Palp: all 
segments short and broad except the tarsus which terminates in a 
long, lash-like embolus (Fig. 8). Abdomen: ovoid; with a weakly 
chitinized epigastric scutum and a narrow, transverse scutum just 
posterior to the genital groove; openings to book lungs and tracheal 
spiracle obscure. Spinnerets as usual in the genus with posterior 
pair the longest. Color in alcohol : carapace a medium brownish with 
three pairs of obscure more or less radiating streaks along lateral 
sides; with a conspicuous, somewhat diamond-shaped figure on the 
posterior declivity subdivided in the middle; only a moderate amount 
of black pigment in the ocular region ; legs, mouth parts and sternum 
yellowish with variations. Abdomen : dorsum and lateral sides purple 
with cardiac region nearly white and with dentate margins; purple 
areas obscurely subdivided into angular areas; venter purplish except 
for the scutal areas which are yellowish streaked with purple; a light 
yellowish median stripe extends posteriorly three-fourths of the 
distance from the genital groove to the spinnerets which are yellowish. 
Female paratype. Total length 1.61 mm. Carapace 0.66 mm long; 
0.51 mm wide opposite second coxae where it is widest; 0.17 mm 
tall ; very slightly arched from PME to beginning of posterior 
declivity; otherwise essentially as in male. Eyes: ratio of eyes 
ALE : PME : PLE = 7.5 : 6.25 : 7. ALE separated from one 
another by nearly three-fifths of their long axis. Clypeus appears to 
be practically eliminated because the ALE are set so low on the 
front of the carapace; otherwise essentially as in male. Chelicerae, 
maxillae and lip : all essentially as in the male holotype and without 
special modifications. Sternum : excavation at base of lip much less
