Psyche 
[September-December 
Males: Carapace. Figs. 50-51. Thoracic groove absent, a slight 
double longitudinal depression, or a shallow double longitudinal pit. 
Postocular setae form a short narrow longitudinal row. Sternum. 
Fig. 60. Posterior sigilla faint, large, and close to one another. 
Pedipalps. Figs. 86, m-113. Tibia strongly swollen ventrally near 
distal end. Embolus base distant from ICS base. Conductor tip 
shaped like knife blade tip. Inner (concave) edge of OCS smooth 
to moderately rough. Leg I. Fig. 93. Tibia and metatarsus with 
ventral, erect to suberect, relatively short, ensiform macrosetae ; 
nearly all rest of setae appressed. Abdomen. Tergites I and III 
much smaller than tergite II; usually reduced to small patches or 
spots at bases of macrosetae. Coloration. Pars thoracica pale yellow 
to pale yellow-brown. Pars cephalica darker; pale brown to medium 
brown. Chelicerae dorsally similar to or slightly darker than pars 
cephalica. Pedipalps dorsally vary from pars thoracica color to 
cheliceral color; sometimes with orange or red tint. 
Females: Carapace. Figs. 52-53. Thoracic groove absent or vesti- 
gial; if latter, it is usually a shallow depression or rarely a shallow 
rounded pit. 2-5 postocular setae form a very narrow longitudinal 
row. Sternum. Figs. 71-73. Posterior sigilla faint, often irregularly 
shaped, large, and very close together. Peripheral sternal setae all 
slender ; sometimes a few to many anterior-lateral ones stout. Longest 
setae scattered over most of sternum. Chelicerae. Fig. 40. Genitalia. 
Figs. 1 55-171. Seminal receptacles extremely weakly sclerotized. 
Stalks very long, nearly same diameter throughout length and 
strongly looped (4-11 bends), sometimes irregularly. Bulbs small to 
medium sized. Coloration. Pars thoracica pale yellow to yellow. 
Pars cephalica darker (at least around margins and median longi- 
tudinal line) ; light yellow to light brown. Chelicerae darker than 
pars cephalica; light brown or light orange-brown to medium red- 
brown. 
Variation. Males: Several male characters show strong geographic 
variation. Two variation patterns are common : often the Sierra 
Madre and Henninger Flats samples are similar to one another and 
divergent from the rest; sometimes the Tehachapi Mountain sample 
is divergent. 
The Henninger Flats males are smaller than any others and the 
Tehachapi Mountain sample exhibits the largest body size average, 
but body size values in the other samples fill the gap between these 
two extremes (Fig. 27). The sternum is markedly broader (Fig. 30) 
and the pars cephalica is distinctly more elongate (Figs. 28, 50-51) 
in the Sierra Madre and Henninger Flats samples than in all others.
