Psyche 
[June 
Male. Carapace: (Figs. 9, 21). Elongate oval. Thoracic groove 
narrow for entire length; center of thoracic groove less than 2/3 
distance from ant. to post, border of carapace. Setae scattered over 
entire pars thoracica, densest at lateral edges. Setae rare to absent 
at base of pars cephalica, becoming numerous higher up. Pars cepha- 
lica weakly elevated, highest at eye group. Height of clypeus at 
ALE 1 to 1 1/2 times vertical diam. of ALE. Diam. of AME 2/3 
to slightly greater than their distance apart. Sternum: (Fig. 35). 
Elongate. 3 post, pairs of sigilla oval. Chelicerae : (Figs. 9, 50-52). 
Apophysis moderately to very thick ; curving downward distally. All 
apophyseal setae attenuate, post, ones stronger than ant. ones. Pedi- 
palps: (Figs. 15, 58-60). Tibia swollen in cylindrical form, of nearly 
equal diam. for most of its length. Outer conductor sclerite of pal- 
pus long, translucent, serrations small; tip rounded to pointed. Inner 
conductor sclerite extends slightly to well beyond edge of outer con- 
ductor sclerite; narrowed and slightly curved distally, rather blunt 
at tip. Leg I: (Figs. 74-77). Tibia with 3 ill-defined longitudinal 
rows of macrosetae (1 prolateral and 2 ventral) running most of its 
length. Tibia nearly straight and cylindrical, curving downward 
slightly at distal end. Metatarsus with 2 ill-defined longitudinal 
lateroventral rows of macrosetae extending most of its length. Meta- 
tarsus nearly straight, decreasing gradually in diam. toward distal 
end. Abdomen: 2 large tergites, second slightly larger than first; 
often a bilateral pair of tiny sclerotized spots post, to second tergite. 
Spinnerets : (Fig. 30) . AL greatly reduced; lacking spigots; not 
more than 1/5 as long as PM, often much less. PM elongate and 
cylindrical; diam. 1/4 to 1/3 length. Coloration: Pars thoracica 
pale yellow to grayish orange. Pars cephalica light brown to brown. 
Sternum slightly lighter than pars thoracica; labium and palpal coxae 
slightly lighter than pars cephalica. Chelicerae light brown to dark 
reddish brown. Palpal femur and patella grayish orange to dark 
orange brown, tibia and tarsus slightly lighter. Leg I dorsally nearly 
as dark as palpal femur; rest of legs lighter dorsally, slightly darker 
than pars thoracica. Abdomen light grayish yellow to light gray; 
tergites darker yellowish gray. Holotype nearer to darker end of 
color range.
