Three new species of pselaphine rove beetle are described from Washington-Lucifotychus lisowskii Owens and Carlton and Pselaptrichus rainierensis Owens and Carlton from Yakima County, and Tychus douglasi Owens and Carlton from Mt. Rainier National Park. These bring the total number of species in each genus to 21, 38, and 37, respectively. A checklist of the North American species of each genus is provided, and the new species are integrated into previously published keys and supported by illustrations of diagnostic characters. A total of 655 specimens of Pselaphinae collected from Mt. Rainier National Park and surrounding localities from 1995 to 2009 yielded records for 19 species, including eight new records for the state of Washington.
