A total of 2,766 specimens were examined and additional data were extracted from unpublished datasets. In total, we have records for 1,383 localities in the PNW. Also included is a brief history of tabanid studies in the PNW, comments on recent changes in scientific names and a discussion regarding intraspecific variation in selected species.
