In this paper we intro- duce three new thrips species for this country. Orothrips priesneri, an aeolothripid species, has a discontinuous Mediterranean distribution. In Serbia it was found at several localities along the course of the Danube, a region with a warm, submediterranean influence. Its general distribution pattern makes its presence in Serbia unex- pected. The hygrophilous species Iridothrips iridis was collected on the leaves of Iris pseudacorus in the vicin- ity of Grocka, near Belgrade. Platythrips tunicatus, which is widespread in Europe, is an oligophagous species related especially to plants from the genus Galium. Keywords: Thysanoptera, thrips, fauna of Serbia, Orothrips priesneri, Iridothrips iridis, Platythrips tu- nicatus. The first data on the thrips fauna of Serbia had been published by Kazakov (1927). After that, Morison and Tanasijevi≥ (1966), Gojkovi≥ (1971) and zur Strassen (1981, 1984) also wrote about these insects in this part of the Balkans. The great thripsologist R. zur Strassen has presented a check-list of Thysanoptera in the area of theYugoslav countries, and specified 65 thrips species for Serbia in the paper published in 1984. As it has already been cited on several occasions, the thrips fauna in the territory of the countries of the formerYugoslavia and especially Serbia, had been studied more inten- sively from the eighties of the last century. The result of these investigations is a significant increase in the number of known species in Serbia. So, in our last published check-list (Trdan et al., 2003) we could list 112 thrips species from Serbia. It means that during this period, the number of known thrips species had increased by 43 percent. Materials and Methods Insects were collected by classic entomological methods – by direct inspection of plant material and by use of a sweeping net. All examined localities were in the surround- ings of Belgrade, except Slankamen which is situated in Srem (Northern Serbia). Most of
