should be deleted from the Hungarian fauna, because the original specimen is Agriotes medvedevi DOLIN, 1960 (checked by V. DOLIN). Ampedus aethiops (LACORDAIRE, 1835) was mentioned by ÁDÁM (1986) from Kalocsa, but this record is based on a misidentified specimen of Ampedus pomorum (HERBST, 1784) (checked by O. MERKL). Ampedus nigrinus (HERBST, 1784) was mentioned by KAUFMANN (1914a: 17) from the Mecsek Mountains in the following sentence: "... nagy ritkán E. nigrinus és E. Megerlei, ezek azonban csak vén lomberdők közelében" [... very rarely E. nigrinus and E. Megerlei, but only in the vicinity of very old deciduous forests]. This suggests that he collected it at least a few times. Unfortunately, not a single unicoloured black specimen of Ampedus was found in his collection deposited in the HNHM, so it cannot be decided which species he actually refers to {Ampedus nigerrimus is the most probable). The species is unknown from any other part of present-day Hungary. Ampedus ochropterus (GERMAR, 1844) was reported by SOMORJAI & ÁDÁM (1996) from the Bükk National Park (Miskolc: Lillafüred), but this record is based on a misidentified specimen of Ampedus cinnabarinus (ESCHSCHOLTZ, 1829) (checked by J. MERTLIK). Ampedus tristis (LINNAEUS, 1758) was mentioned by KUTHY (1897) from Szeged, but the presence of this mountainous species in one of the driest and hottests parts of the Great Hungarian Plain is improbable. The record may be based on misidentified, mislabelled or accidentally introduced material. No original specimens are available. Cidnopus aeruginosus (OLIVIER, 1790) was mentioned by ÁDÁM (1986), ENDRŐDI (1983), HORV ATOVICH ( 1979), KUTHY ( 1897), MERKL ( 1998) and PlLLICH ( 1914). While occurrence of this species is not improbable in Hungary, all original specimens of those published records are in reality Cidnopus ruzenae (LAIBNER, 1977) (see remarks in the new species section above). Harminius undulatus (DE GEER, 1774) was mentioned by BÉRCI (1981) from the Hortobágy National Park (Egyek: Ohati-erdő), based on a misidentified specimen of Stenagostus rhombeus (OLIVIER, 1790) (checked by O. MERKL). Liotrichus affinis (PAYKULL, 1800) was mentioned by KAUFMANN (1914a, b) from the Mecsek Mountains in the combination "Selatosomus affinis". It is quite unlikely that this species, known from the higher zones of the Carpathian Mountains could occur in low-lying range. The record is almost certainly based on a misidentification or the incorrect use of the name. No original specimen is available. Melanoms dichrous (ERICHSON, 1841) was mentioned by KUTHY (1897) from Isaszeg, based on a misidentified specimen of Melanoms tenebrosus (ERICHSON, 1841) (checked by V. DOLIN). Zorochros ibericus (FRANZ, 1967) was mentioned by MERKL (1999) from the Aggtelek National Park (Szalonna: Bódva), but the material on which this record is based represents a misidentified (small) specimen of Zorochros quadriguttatus (LAPORTE DE CASTELNAU, 1840) (checked by J. MERTLIK). CHECKLIST OF HUNGARIAN ELATERIDAE In the subsequent checklist species with no localities from present-day Hungary in KUTHY (1897) or not mentioned by him are followed by references. These are based on reliably identified specimens from Hungarian localities. Efforts were made to locate all publications in which first records for Hungary were published, but it is not impossible that cryptic earlier literature sources have been overlooked.
