Folia Historico-Naturalia Musei Matraensis - A Mátra Múzeum Természetrajzi Közleményei 8. (1983)
Kiss, O.: A study of the Trichoptera of the Szalajka Valley near Szilvásvárad as indicated by light trap material
its quality can be considered good — with the exception of those specimens trapped on rainy days. The imagos are stored in microvials filled with isopropil alcohol and can be found in the Mátra Museum. CONCLUSIONS During the one-year operation of the light trap 4315 specimens of 46 species were caught and values of dominance for species were calculated. Of the 46 species the larvae of 20 species had been collected in 1974/75. FLIGHT PERIODS RHYACOPHILIDAE 1.

Synagapetus Mac LACHLAN genus has become known from the territory of Hungary in the past decade only, and several of its species have been collected by J. OLÁH and Z. VARGA. Synagapetus mosely ULMER is present in Rumania, Czechoslovakia and Austria and was collected in the Vörös-kő Valley and Szentléleki Valley as well as the Vadász Valley in Hungary by J. OLÁH and Z. VARGA. 5. Synagapetus mosely ULMER: Jun 15, io; Jun 17, 10. 98
