onis (Giraud, 1861), Abia fulgens Zaddach, 1878, Fenella nigrita Westwood, 1840 and Aglaostigma discolor (Klug, 1814). During the formation of the Symphyta fauna of the Carpathian Basin we may safely state that significant role was played by the European, Euro-Siberian and pan-Palaearctic elements and a rather minor role by the Holarctic species. This fauna cannot sharply be delimited from the surrounding faunae of the extra-Carpathian territories, since in many instances the inter-relationships are clearly evident. This fact, however, suggests that the significant changes in the weather conditions of the Upper Pleistocene obviously influenced the development of the vegetation cover which in turn that of the present composition of the fauna, including that of the sawfly communities. This argument does not exclude the fact that in certain cases endemic species evolved within the boundaries of the Carpathian Basin, or that some special species segregated off and became independent outside of the Basin. A peculiar example is Elinora sabariensis (Mocsáry, 1880) which has been considered as a true endemism of the Carpathian Basin in the last one hundred years. Recently it was recorded from the steppe of the Ukraine. The second author emphasized that it was found only in dry, sunburnt, steppe-like clearing of a depression, slopes of southern exposition and on sandy hilltops. The expansion of the species, of course, cannot be imagined across the Carpathians, but rather along the Danube valley. Another example is Calameuta idolon (Rossi, 1794) which occurs in the Basin but was also recorded from the steppe of the Ukraine and the Crimea. To sum it up, it is for sure that the formation of the Symphyta fauna of the Carpathian Basin strictly adhered to the changes of the plant cover which suffered the most in the Upper Pleistocene. * The second and subsequent parts will give a list of sawfly species, unpublished before, collected in the eastern, mostly mountainous regions of the Carpathian Basin lying within the boundaries of Romania and the westernmost reaches of the Ukraine.
