Dorsum of abdomen light brown to brown with pair of black 
anterior-lateral patches as in Figure 5. Anterior cream to yellow

area faintly indicated. Venter of abdomen cream or light beige to 
pale yellowish brown. Few scattered darker spots. Overlaid with 
fine coat of white hair. 
Legs yellow or pale yellow-orange to yellowish brown, darker 
distally. Femora with dusky bands on dorsal and lateral surfaces. 
Ventral surface lighter yellow. 
Labium and endites brownish orange to brown with distal ends 
yellow to cream. Sternum yellow to light golden brown. 
Color. Males. Face yellow to yellow-orange, darker brownish 
in eye region. Chelicerae with basal areas yellow to orange-yellow, 
darker brown to reddish brown distally. Condyles orange-yellow to

Carapace brown with a broad median yellow stripe and irregular 
yellowish submarginal stripes obscured by thicker clothing of white 
hair. 
Dorsum of abdomen beige to light brown with black markings 
along sides beginning anteriorly and continuing posteriorly. Black

without distinct chevrons as in other species. Venter of abdomen

dant laterally.

Diagnosis. Gladicosa gulosa is closest to G. pulehra in size and 
coloration. The markings of pulehra offer greater contrast, and 
chevrons are usually visible on the dorsum of the female abdomen 
(compare Fig. 5 with Fig. 4). The epigyna of the females and the 
palpi of the males also resemble one another in appearance, but are 
distinctly different when compared in detail. The epigynum of 
gulosa has the transverse piece entirely pearlescent white, whereas 
pulehra has some white, but nearly always shows darker brown 
sclerotized areas on the transverse piece (compare Figs. 6, 8, 9 with 
Figs. 10, 11, 13, 14). In gulosa the embolus is pointed at the end, 
whereas that of pulehra is somewhat spatulate in shape (compare 
Figs. 35, 36 with Figs. 37, 38).
