Color. Males of 0 . bifissus occur in two color phases. The darker 
of these forms is described first, then the lighter phase. 
Dark male. Face and chelicerae dark brown with vertical black 
stripes as in Figure 57. Eye region dark brown with iridescent 
scales. Cymbia of palpi dark brown to black. Distal ends of cheli- 
cerae lighter. 
Carapace with median area light brown, bordered by dark brown 
to black as shown in Figure 58. 
Dorsum of abdomen light brown in center to dark brown along 
sides as in Figure 58 ; overlaid with iridescent scales. Spinnerets 
yellow to light orange-brown. Venter dark brown to black with 
pale lines originating at corners of epigastric furrow and continuing 
to base of spinnerets. Median area heavily clothed with iridescent 
scales. Scales impart a green or pink iridescence in preserved speci- 
mens. 
Legs yellow to light orange-brown. Longitudinal black line along 
retrolateral surface of femora I. 
Labium and endites dark brown to black with pale distal ends. 
Sternum brown. 
Light male. Face and chelicerae orange-brown with vertical black 
stripes as indicated in Figure 59. Distal ends of chelicerae pale 
yellow. Eye region with a few iridescent scales. Cymbia of palpi 
dark brown. 
Carapace light orange-brown, darker along sides as shown in Fig- 
ure 60. 
Dorsum of abdomen white to pale cream, overlaid with iridescent 
scales, bounded by darker brown as in Figure 60. Spinnerets orange- 
yellow. Venter white to pale cream spotted with brown. 
Legs cream to pale yellow. 
Labium and endites pale yellow-orange. Sternum pale yellow. 
Diagnosis. Oxyopes bifissus is similar to O. bifidus in form and 
coloration. The male palpi of these two species are much alike, but 
distinct (compare Figs. 84-89 with Figs. 78-81). The two species 
can be readily distinguished by their epigyna (compare Figs. 37, 38 
with Figs. 25-30) . 
Distribution. Eastern Mexico to Costa Rica (Map 1).
