FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK LX 1999 pp. 349-354 Data to the distribution of Oligoneuriella larvae in Hungary (Ephemeroptera: Oligoneuriidae) T. Kovács, A. Ambrus and K. Bánkuti Data to the distribution of Oligoneuriella larvae in Hungary (Ephemeroptera: Oligoneuriidae) — Collecting data of larvae of four species of Oligoneuriella are listed and depicted in UTM maps. Literature data of adults are revised. A key to the identification of larvae is given. Oligoneuriella kejfermuellerae and Oligoneuriella polonica are new to Hungary. INTRODUCTION This paper presents the results of investigations on four Oligoneuriella species recorded from Hungary. It is based on 557 collectings of larvae carried out between 4th August, 1994 and 28th November, 1998 in 407 localities. The larval material is preserved in 70% ethanol and deposited in the Mátra Museum (Gyöngyös). The adults studied by the authors are housed in the Department of Zoology, Hungarian Natural History Museum (HNHM) (Budapest). As for information about the areas investigated, methods of collecting and presentation of data see Kovács et al, (1998).
