Discusssion Two third of the total material belonged to Hydropsyche species. The quantity of Hydropsyche females almost reached 60 p. с This large mass is characteristic of slow running waters (Nógrádi and Uherkovich 1988). Ceraclea dissimilis Steph. and Neureclipsis bimaculata L. surpassed 10 p. с These two species live in almost all running waters of Hungary. Anabolia turcata Brau., Halesus tesselatus Rmb. and Psychomyia pusilla F. are also frequent species of such type of waters. Setodes punctatus

'F., Ceraclea annulicornis Steph., Cyrnus trimaculatus Curt., Goera p/iosaF. and Ithytrichia lamellarisEaton are rarer than the previous ones. The collection of numerous specimens of Platyphylax irauenfeldi Brau, is the most important result of the lighttrapping at Szentborbás. This is one of the rarest species of Europe. McLachlan (1874-1880) mentioned it from the city of Wien, a specimen had been collected by the author (Brauer) on Josefsplatz. In the same work Marseilles was published, as the collecting site of Platyphylax pallescens McL. This species proved to be a synonym of P. frauenfeldi Brau. Malicky (1975, 1988) gave its occurrence from Upper and Lower Austria, and Styria, and he established that P. frauenfeldi Brau, is an „exceptionally rare species" being very sensitive to pollution. Its Austrian occurrences localited along larger rivers. The uncertain locality from Styria was published by Malicky (1979) after Strob's (1906) paper only. Botosaneanuanĉ Malicky

(1978) reported it from five regions of Europe. The first Hungarian specimen was reported from Magyarszombatfa, W. Hungary [Újhelyi 1981 a), later another male was captured at Bares Juniper Woodland (Újhelyi 1981b). Its two other sites were published from the Zselic Downs: Kaposfő and Bőszénfa (Nógrádi and Uherkovich 1990). In the material of other light traps further specimens were found (Sumony 1990, Szentpéterfölde 1989, 1990; unpublished). Its correct biotope has not been known until recent time. At Szentborbás 51 specimens (40 males, 11 females) were captured from 25th October till 2nd November. It is more than all specimens having been collected since its description in 1859. We can suppose that its larvae live in the river Drava. The specimens which were captured earlier at Barcs-Középrigóc and at Sumony might develop also in Drava but after hatching they were swarmed from their biotop. The other localities are far from large river but they are along small, unpolluted, slow streamlets (Kaposfő, Bőszénfa, Magyarszombatfa, Szentpéterfölde). Its Hungarian distribution is given on Fig. 2, a new figure of male and female genitalia can be studied on Fig. 3. Some other species of the 44 are rare and characteristic ones.
