Romania: 4635/2250 Bihor Mts; 4559/2150 Lovrin (SUCIU, 1973). Due to a wide spectrum of host organisms and the eurychronous occurrence of the imagines, it is not difficult to find out the presence of this species. Despite that facts, data on it's occurrence in Hungary and the Pannonian lowland in general are scarce, Megabothris turbidus is distributed continuously In forests of submountain and mountain zone of the Carpathians and of collinous zone of the eastern margin of the Alps (Fig. 2). It was not registered in hills and lower mountain ranges of Hungary, but it is known from the top parts of the mountains Mátra, Bükk and Zemplén, that have developed native beech forests (Fagetum). There occur, besides submountain and mountain regions, several relic populations of M. turbidus in the Pannonian lowland nevertheless, which they are closely related to large, occasionally flooded (until the half of a recent century) alluvial forests, e.g., Salici-alneta, Saliceta albae, Ulmi fraxineta-populi (groups of natural biogeocenoses, according to RAUSER, ZLATNIK, 1966). Few data are known also from the environs of large wetlands like Neusiedl and Balaton lakes. Records of this species along waters'edges of smaller rivers are scarce and depend on the presence of native alluvial woodlands, or their remnants at least. In the case of neophytes, e.g. artificially planted Populus canadensis, we still suppose the continuum of a forest ecosystem. M. turbidus does not occur in original steppe and forest-steppe zones of the Pannonian lowland, nor in secondary steppes (agricultures) of lowlands and hills. It was not registered in forests of lowlands, hollows and submountain zones of separed mountain ranges in the Carpathian Basin and the southern slopes of the Western Carpathians, That is related to forest biocenoses of Quercetum
