Ambrus, A., Juhász, P.; Bánkuti, K.: New Hungarian mayfly (Ephemeroptera) species arising from collectings of larvae
species. On the Dráva and the lower reaches of the Rába (Sárvár) we collected the species characteristic of plains (Pseudocentroptilum nanum, Neoephemera maxima, Brachycercus minutus). Sziráki (1995) listed 72 Ephemeroptera species occurring in Hungary, that number increases to 84 with the species published in our paper. The occurrence of further species is still expected. Acknowledgements We are grateful to Adam Glazaczow, Nikita Ju. Kluge and Peter Malzacher for their help in the elaboration of the material. I. Turcsányi must be acknowledged for the data of Brachycercus minutus from the Tisza. References Andrikovics, S.
