also omitted. So, only those records are taken into account from Újhelyi (1959) which were new as compared to the former literature. In case of taxonomic or nomenclatural changes the name originally used in the referred publication is given in parentheses. Omitted are also all records based on specimens only doubtfully identified by the respective author himself: Ecdyonurus helveticus (Eaton, 1885): Sátori 1939a; Ecdyonurus fluminum (Pictet, 1843) [= ? E. dispar (Curtis, 1834)]: Andrikovics 1991a, Csörgits 2000; Ecdyonurus subalpinus Klapálek, 1905: Csörgits 2000; Rhithrogena germanica Eaton, 1885: Tóth 1992a. Caenis lactea, without author and year of description, was mentioned by Bába & Ferencz (1971), Andrikovics & Kiss (2000) and Szitó (2002). It is unclear whether this name refers to Caenis lactea (Burmeister, 1839) or Caenis lactea Pictet, 1843. The latter is presently (Malzacher 1986 et auct. sequ.) considered to represent a synonym of Caenis horaria (Linnaeus, 1758). Also not included in the present check list are the following species, which have been listed by Tóth (1992/?), but which refer to localities outside of presentday Hungary according to the references mentioned by him: Siphlonurus alternatus (Say, 1824), Rhithrogena hyhrida Eaton, 1885, Ecdyonurus macani Thomas et Sowa, 1970, Electrogena quadrilineata (Landa, 1969), Behningia ulmeri Lestage, 1929 and Palingenia fuliginosa (Georgi, 1802). The occurrence of some species previously quoted for Hungary remains doubtful in the absence of reference specimens: Ecdyonurus forcipula (Pictet, 1843) has been reported by Pongrácz (1914) from Nagymaros. At present Ecdyonurus forcipula (Pictet, 1843) is considered a no men dubium (see Bauernfeind & Humpesch 2002 for further references) and it cannot be ascertained to which species the specimen from Nagymaros actually referred. Epeorus alpicola Eaton, 1871 has been recorded by Pongrácz ( 1936) from the Mátra Mountains. Sátori (1939a) again cited this record, but the species was no longer mentioned in comprehensive works published later (Újhelyi 1959, 1966, Tóth 1992a) and could not be found during recent extensive collectings in the Mátra Mountains (Kovács 2001). Larvae of Epeorus alpicola develop in rather cold streams, usually above 1000 m a.s.l. or at the foot of high mountains (Bauernfeind 1994). Rhithrogena ferruginea (Navas, 1905) was mentioned by Andrikovics (1991a, b) following Sowa (1971). The taxon is presently considered to be restricted to Spain (Sowa & Degrange 1987 et auct. sequ.) and the Hungarian record may belong to one of several taxa of the "Rhithrogena semicolorata-group"
