Diagnosis. Oxyopes bifidus is most closely related to O. bifissus 
as evidenced by coloration and morphology. The male palpi are very 
similar (compare Figs. 78-81 with Figs. 84-89), but distinct. The 
two species are easily separated by epigynal structure (compare Figs. 
25-30 with Figs. 37-38). Preliminary collecting indicates that these 
two species are largely allopatric, O. bifidus occurring in western 
Mexico and Central America and O. bifissus in eastern Mexico with 
one record form Costa Rica. 
Natural History. Oxyopes bifidus was collected in Panama and 
Costa Rica by sweeping tall grass and herbaceous vegetation. Ox- 
yopes salticus was present in these same habitats in much greater 
numbers than O. bifidus. No differences were noted in the micro- 
habitats of these two species. 
Distribution. Western Mexico to Panama (Map 1).
