Male holotype. Total length 4.19 mm, including quite porrect 
chelicerae and extended spinnerets. Carapace 1.52 mm long; 1.38 
mm wide; about .53 mm tall, exclusive of the prominent lateral ocular 
tubercles; with the usual long, slender spines; surface between the 
spines smooth; with no median thoracic groove. Eyes: viewed from 
above, posterior row strongly recurved, anterior row moderately so; 
viewed from in front, anterior row straight, measured by centers. 
Central ocular quadrangle wider behind than in front in ratio of 
about 3:2; nearly as long as wide behind. Posterior row occupies 
nearly four fifths of width of carapace at that level. Ratio of eyes 
AME : ALE : PME : PLE = 5 : 10 : 6 : 10. AME separated 
from one another by slightly more than twice their diameter, from 
ALE by 2.6 times their diameter. PME separated from one another by 
nearly three times their diameter, from PLE by 4.6 times their diam- 
eter. Laterals separated from one another by 2.7 times their diameter. 
Clypeus porrect in the usual manner; apparently with the usual long, 
slender spines near ventral border (judged by scars) ; height, includ- 
ing membranous ventral border, equal to about seven times the diam- 
eter of AME. Chelicerae, maxillae, lip and sternum all apparently 
typical of the genus. Legs: 1 = 243 in order of length; first and 
second nearly twice as long as third and fourth; with many spines; 
tarsal claws as usual; trichobothria observed on tibiae, metatarsi and 
tarsi. Palp: patella short, unmodified; tibia with conspicuous 
apophyses and features of the tarsal bulb as shown in Figures 1-2. 
Abdomen : elongated and somewhat cylindrical ; without special mod- 
ifications; with numerous long, conspicuous, slender, dorsal spines. 
Color in alcohol : rather conspicuously colored ; carapace yellowish with 
a narrow, red, ventral, marginal band; a dorsal, irregular, V-shaped
