Three new and a rare true bug species in the Hungarian fauna (Heteroptera: Dipsocoridae, Reduviidae, Lygaeidae) A. TORMA Tisza Research Group of the Hungarian Academy of Sciences and Department of Ecology University of Szeged, H-6701 Szeged, P.O. Box 51, Hungary, E-mail: torma_a@yahoo.com Abstract - Cryptostemma (Harpago) medium REY, 1888, Empicoris uniannulatus (SIGNORÉT, 1852) and Aoploscelis hivirgata (COSTA, 1853) are recorded for the first time from Hungary. Occurrence of Empicoris gracilentus (JAKOVLEV, 1907) in Hungary is confirmed. With one figure. Key words - Dipsocoridae, Reduviidae, Lygaeidae, Hungary, new records. The Hungarian Heteroptera fauna is well known, but there are less explored regions, for example floodplain areas of the rivers Tisza and Maros. It is therefore not surprising that some new or rare species in the Hungarian fauna were found in these areas. The examined material was collected in Csongrád county in the years of 1992 and 1993 using pitfall traps near the Tisza, and in 2002 individual collecting was carried out on the sandbanks of the river Maros. In the material, three species new to the fauna of Hungary, furthermore a rare and remarkable reduviid bug has been found. Cryptostemma (Harpago) medium REY, 1888 - Hungary, Csongrád county: Makó, bank of River Maros, sandbank, 25. VII. 2003, leg. FÜLÖP; 1 New to the fauna of Hungary. Cryptostemma HERRICH-SCHÄFFER, 1835 is the only Palearctic genus of the family Dipsocoridae, and 9 species of different subgenera have been reported to occur in Europe (KERZHNER 1995). The Hungarian dipsocorid fauna includes 3 species which are insufficiently studied. Only one Hungarian record of C. (Cryptostemma) alienum HERRICH-SCHÄFFER, 1835 is known so far (KONDOROSY & FÖLDESSY 1998), and we know more data on the species C. (Pachycoleus) waltli FIEBER, 1860 and C. (Pachycoleus)pusillimum (J. SAHLBERG, 1870) just recently (RÉDEI & HUFNAGEL, 2002). The third subgenus, Harpago LlNNAVUORI, 1951, has not been known to occur in our areas so far. This subgenus is not difficult to identify by the genital region of the male, which is asymmetric and very complicated with several appendages (LlNNAVUORI 1951). C. medium is a new species to the Hungarian fauna,
