Diagnosis. Oxyopes felinus has the over-all black and white color 
pattern of other members of the tridens group. It does not have a 
strongly developed patellar apophysis, such as that found in O. tri- 
dens and O. pardusj but has a small protuberance on the patella. 
Oxyopes felinus is most closely related to O. cornutus, resembling 
this species in color and male and female reproductive organs. It 
can be distinguished from O. cornutus by reference to the epigyna 
(compare Figs. 39, 40 with Figs. 43, 44) and the male palpi (com- 
pare Figs. 102, 103 with Figs. 104, 105). 
Distribution. Arizona, Sinaloa, Nayarit (Map 2).
