Tonella tenella occurs from San Benito County, California, and the High Sierra Nevada north to Washington mostly in the Cascade and Coast ranges but extending eastward through the Columbia River Gorge. Disjunct populations occur in central Oregon, and on Saltspring Island and Mount Tzouhalmen on Vancouver Island in southwestern British Columbia.
