MISCELLANEA ZOOLOGICA HUNGARICA Tomus 13. 2000 p. 81-83 New Hungarian mayfly (Ephemeroptera) species arising from collectings of larvae II. by T. Kovács, A. Ambrus and P. Juhász (Received May 5,1999) Abstract: This paper deals with two new mayfly species for Hungary: Baetis tricolor, Brachycercus europaeus. The localities of the collected specimens are indicated on a UTM map. Keywords: Hungary, Ephemeroptera larva, faunistics, distribution, communities, habitats Introduction Since we have published the first part of this paper the Hungarian Ephemeroptera fauna has been further enriched with two new species [Oligoneuriella kejfermuellerae, O. polonica - Kovács et al. (1999)] as a result of the collecting of Ephemeroptera larvae. Between 8 th April 1994 - 28 th November 1998 on 407 sampling points 557 collectings were carried out. During these samplings two new species were found: Baetis tricolor and Brachycercus europaeus. The information regarding the study area, collecting methods and the structure of the published data is the same as in Kovács et al. (1998). The collected material is preserved in 70% ethanol and is deposited in the Mátra Museum (Gyöngyös).

Olajos. This species has a Transpalaearctic distribution (Kluge 1997). It was found in different habitats of the rivers, usually from the slowly flowing edge of the water, it was collected from stones, from the sediment and from among the submerged aquatic plants. Most often the following species were found at the same sampling points: Heptagenia flava, Caenis
