S. Mahunka szerk.: Folia Entomologica Hungarica 62. (Budapest, 2001)

Germany, Romania (see references in Zwick 1973) and more recently from Serbia (Sivec 1980) and the Czech Republic (Soldán et al. 1998). /. pawlowskii is regarded as a potamophilous species. Adults have been found at several sites along the River Rába: Bodonhely, Rábahídvég, Sárvár. Agnetina elegantula (Klapálek, 1905) — For the first time in Hungary, Kovács & Ambrus (2000) published data on larvae from the River Rába. Later on larvae were found in the River Lapines at Szentgotthárd and in the River Rába from Szentgotthárd to Sárvár - along with Isogemts nubecula (Kovács & Ambrus in press). One male adult was found on the bank of the River Rába at Rábahídvég. Isoptena serricornis (Pictet, 1841) — The first Hungarian record by Újhelyi (1979) was from the fish ponds at Haj máspuszta in the Bakony Mountains. Considering the ecological requirements of this potamophilous and psammophilous lowland species, this record is doubtful, and the original specimen, unfortunately, cannot be found. However, Újhelyi (1979) mentioned another specimen from the bank of the Danube at Nagytétény, which is now in the collection of the Hungarian Natural History Museum (1 male, 07.06.1970., leg. and det. Újhelyi). One more specimen from Zalakaros kept in this collection is misidentified as Isoptena serricornis. Thus, the sampling site described here, Tiszabercel (bank of the River Tisza), is the second known reliable locality for this species in Hungary apart from Nagytétény (bank of the Danube). Siphonoperla taurica (Pictet, 1841) — New to Hungary. This species is known from the Crimea Peninsula and from Central Europe. It was forgotten for a long time until Zwick (1972) clarified its identity. Today records exist from Germany, Austria, Slovakia and the Czech Republic (e. g. Zwick 1973, Rauser 1977). Adults have been collected along the Kerca stream at Kercaszomor and on the bank of the River Rába at Körmend, Magyarlak, Molnaszecsőd and Rábahídvég. Taeniopteryx schoenemundi (Mertens, 1923) — So far only larvae are known from two places of the Upper Tisza in Hungary: Szatmárcseke, Tiszabecs (Juhász et al. 1998, Kovács et al. in press). In March a male and a female specimen were collected at the above-mentioned two places on the bank of the River Tisza. The male from Szatmárcseke has metafemoral thorns and thus could be identified as T. stankovitchi, described from Macedonia by Ikonomov (1978). More recently this species has been recorded from Italy and apparently the metafemoral thorn is the only reliable character to separate "stankovitchi" from "schoenemundi" (Fochetti & Nicolai 1996). Because of the intraspecific variability of this feature, as observed in one of the Italian populations, the authors suspect synonymy of "stankovitchi" with "schoenemundi"

. We share this suspicion, which is supported by a similar observation from a site in Southern Germany. The small series from Central Bavaria (coll. AW) includes three males. One specimen is without any traces of thorns and another one with a slight protrusion on only one side, the third male has a similarily slightly indicated thorn on one, but a well developed one on the other femur. Amphinemura standfussi (Ris, 1902) — The first Hungarian record is from the Bükk Mountains: Sebes víz (Újhelyi 1969). Steinmann (1968) published it from Parádsasvár, but Tóth (1989) did not mention this datum in his paper about the genus Amphinemura - probably because of the lack of the original specimen. One male adult now has been found in the Sopron Mountains.
