Male. Carapace: (Figs. 3, 17). Elongate oval. Thoracic groove 
narrow for entire length; center of thoracic groove clearly less than 
2/3 distance from ant. to post, border of carapace. Setae present 
only near edge of carapace and around eye group. Pars cephalica 
weakly elevated ; highest at ocular protuberance. Height of clypeus 
at ALE about equal to vertical diam. of ALE. Diam. of AME 
3/4 to 2 times their distance apart. Sternum: (Fig. 39). Elongate. 
3 post, pairs of sigilla circular to oval. Chelicerae : (Figs. 3, 47-49). 
Apophysis relatively slender, strongly curved downward near distal 
end. Apophyseal setae all attenuate, post, ones stronger than ant. 
ones. Pedipalps: (Figs. 10-13, 53-56) . Greatest diam. of tibia is 
about 1/3 the distance from proximal to distal end; tapers to much 
smaller diam. distally. Outer conductor sclerite of palpus heavily 
sclerotized, relatively short and wide, serrations strong; tip very 
broad and nearly straight across. Inner conductor sclerite extends 
far beyond end of outer conductor sclerite in unflexed condition; 
distally curved and gradually tapering to rather sharp tip. Leg I: 
(Figs. 68-70). Tibia usually with a prolateral row and an ill-defined 
double or single row of macrosetae on the retrolateral aspect of the 
ventral surface extending most of its length; 1 to 3 (very rarely o) 
macrosetae ventrally at very distal end. Tibia nearly straight and 
cylindrical, curving slightly downward at distal end. Metatarsus 
with 1 to 3 macrosetae ventrally at very distal end, rarely with one 
on prolateral surface 1/3 of way from proximal to distal end. Meta- 
tarsus long and slender, tapering slightly toward distal end, nearly 
straight in lateral view, slightly bowed in ventral view with prolateral 
surface concave. Abdomen: Large, median, longitudinal, tri-nodal 
dark pattern. Large tergite in central node. No other tergites. Spin- 
nerets: (Fig. 31). AL only weakly sclerotized terminally with spigot 
at tip, or sclerotized terminally without spigot. AL 1/3 to 1/2 as 
long as PM. PM slightly expanded to unexpanded distally; maxi- 
mum diam. from 1/4 to slightly over 1/3 length. Coloration: Pars 
thoracica yellowish gray to pale greenish brown. Pars cephalica pale 
greenish brown posteriorly, becoming brown to reddish brown an-
