Abstract
The paper reports on new and previously not well-known data on insufficiently studied fauna of aphids living on coniferous trees in Central Siberia of the basin of Yenisei river. This region is the extensive transect of latitudinal geographic zones from semi-desert in the South to the arctic deserts in the North. That is why this region is very peculiar. This is the reason for insufficient study of regional entomological fauna. Aphids (Homoptera: Aphidoidea) are a very taxonomically and ecologically heterogeneous group of insects. The aphids living on conifer trees are not studied completely on the territory of Yenisei basin. Due to this, the studying of not well-known and economically important aphids is actual. For example, the insufficient study of regional aphids is confirmed by the fact, that during three weeks only of the work for INTAS-94-0930 Project two new aphid species were found and described on this territory. Also, the new species of family Mindaridae, which was described in Mongolia in 1980, was found in Siberia for the first time. These finds indicate the real possibility to describe an interesting conifer aphid complex in the absolutely unstudied forested territory between Angara and Lower Tunguska rivers. Geographical location, dates of collection and feeding preferences of different species are described. A general review of Yenisei basin Siberian aphid fauna is suggested for the first time ever.
