N2 - From the 157 species of the family Ceratopogonidae recorded in the Czech Republic 65 species have been found. This represents 41.4 % of the total Czech fauna. Most of the studies published so far were conducted in biotopes with optimal conditions for the larval development or for the existence of adults and their feeding opportunities - in the springs of small brooks, in the inundation area of large rivers, in mountain biotops, thus in the regions with little antropogenic influence. The present results are the first ones from an industrially affected area. Altogether 13 species (20 %) have been recorded for the first time in the Czech Republic: Nilobezzia posticata (Zetterstedt, 1850), Clinohelea unimaculata (Macquart, 1826), Atrichopogon alveolatus Nielsen, 1951, A. epicautae Wirth, 1956, A. winnertzi Goethgebuer, 1922, A. muelleri (Müller, 1905), Ceratopogon communis Meigen, 1804. Forcipomyia phlebotomoides Bangerter, 1933, F. frutetorum (Winnertz, 1852), F. radicicola Edwards, 1924, Dasyhelea flavoscutellata (Zetterstedt, 1850), D. arenivaga Macfie, 1943 and D. ermeri Remm, 1967. This result might be due to the fact, that the area hosts a young biocoenosis developing towards a climax. In the final stage of developement the number of species would be probably lower. One specimen of Atrichopogon sp. could not be identified based on recent knowledge. Remarkable is the occurrence of Atrichopogon epicautae known from North America only and recorded in the Czech Republic for the first time. It would be advantageous to make more detailed investigations of this Holarctic species in Central Europe. The species of Forcipomyia (Euprojoannisia) palustris should be not changed with F. (Thyridomyia) palustris. In the Checklist of Diptera (ORSZÁGH et al. 1997) is this species mentioned as F. (E.) hirtipennis (Malloch, 1915) what is a synonym of F. (E.) palustris (BORKENT & WIRTH 1997). The species of Forcipomyia radicicola is actually processed and probably also published by R. Szadziewski (Poland). The spectrum of species found in the study area is supposedly not complete, because the examined material was selected from a stillion of specimens. The found species excludes biting midges with a crepuscular and nocturnal activity, because used collection methods are only appropriate for biting midges with diurnal activity. To obtain a complete spectrum of species it would be necessary to collect also at dusk or at night using some kind of light trap or emergence traps (with CO2, nulliparous females) at the peak of their activity. The locality hosting the most diverse ceratopogonid species spectrum appears to be Holibka (29 spp.), followed by Jirásek III and Lom (both 24 spp.) and a floodplain forest near Duchcov (21 spp.) The most common species in the study area were as follows: Atrichopogon winnertzi (found in 7 localities), Forcipomyia velox, F. tenuis (both found in 6 localities), F. bipunctata, F. tenuisquama and F. ciliata (all found in 5 localities).
