Abstract. Scolytids constitute an insect group of forest ecosystems that is very important both ecologically and economically, and which has been well studied in most European countries. However, new species are found quite often, especially in regions searched less intensively to date. In this paper three species of scolytid fauna not previously known in Romania are reported for the first time: Trypodendron laeve, Xylosandrus germanus and Hylastes linearis. Individuals of all three species were collected in the north-eastern part of Romania. T. laeve was found only in natural coniferous forests, at altitudes above 1230 m and in association with T. lineatum, but in much lower abundance. The Asian species X. germanus was found in an old beech forest situated at a much higher altitude (760-900 m) than observed in western and central Europe. The third species, H. linearis, was captured as a single specimen in a plateau region (375 m).
