Diagnosis. Oxyopes tibialis is closest to O. acleistus as it is under- 
stood in this paper. Color patterns of these two species are alike 
(compare Figs. 5, 6 to figs. i-6 of Brady, 1964), and the male and 
female reproductive organs are similar. The two species can be dis- 
tinguished by comparing the epigynum of O. tibialis (Figs. 35, 36) 
to that of O. acleistus (figs. 13-20 of Brady, 1964). In males, the 
tibial apophysis of O. tibialis (Figs. 94-97) is larger than that of 
O. acleistus (figs. 35-38 of Brady, 1964) and their palpal sclerites 
differ.
