Johanson, K. A. Systematic revision of the American Helicopsyche of the subgenus Feropsyche (Trichoptera, Helicopsychidae). 2002. 147 pp. SEK 200.

Sixty-four of the seventy-two American Helicopsyche von Siebold, 1856, species within Feropsyche Johanson, 1998, are re-described based on type material and non-type material when types are unavailable.


Reproductions of the original descriptions of the remaining eight species are given in order to present a comprehensive overview of the subgenus in America. Helicopsyche woytkowskii Ross, 1956, earlier synonymized with Helicopsyche peruana Banks, 1920 is considered a valid species. Helicopsyche falcigona Botosaneanu & Flint, 1991a, earlier synonymized with H. ochthephlebia Flint, 1968 is considered a valid species.


Helicopsyche molesta Botosaneanu in Botosaneanu & Hyslop, 1998 is considered a good species. Helicopsyche margaritensis Botosaneanu, 1959, is considered a junior synonym under Helicopsyche vergelana Ross, 1956. Valvata agglutinans Lechmere Guppy, 1864 is considered a synonym under Helicopsyche maculisternum Botosaneanu & Alkins-Koo, 1993.


A key to the males is presented, and maps showing the distribution of all examined species based on the examined material is given.
