ABSTRACT: The genus Oliarus in North America north of Mexico was studied with emphasis on the morphology of the male terminalia. The aedeagal complexes of 36 pre viously described species were illustrated for the first time. Six species proposed as new to science were described and illustrated. A change of status was proposed for one species, a new name given to another species, lectotypes were designated for two species, and three nominal species were relegated to synonymy. Fifty-one species in the study area were considered as valid, with each species receiving attention as to important features of the external morphology, male terminalia, diagnosis from similar species, location of type material, morphological variation, seasonal and geographical distribution, and other biological information when available. Re marks on relationships and a key to the species, based on male terminalia, were also included.
