Orthopsyche was first proposed as a genus in 1976 by Alex G. McFarlane, including two species previously identified as Hydropsyche. McFarlane named Orthopsyche fimbriata(McLachlan, 1862) as the type species.[3] Phylogenetic analysis indicates that Orthopsyche forms a clade with the genus Aoteapsyche.[4]
In 2006, János Oláh, Kjell Arne Johanson and Peter C. Barnard greatly expanded Orthopsyche, by synonymising Abacaria Mosely 1941, and Caledopsyche Kimmins 1953, and describing 29 new species.[5] In 2008, Oláh and Johanson further proposed that Aoteapsyche was a symonym of Orthopsyche.[6]
