Scale:

1:20 000 000.

Accuracy of the map:

Created using maps with a scale of 1:40 000 000;information taken from published literature; and an analysis of the collections of the Zoological Institute, Russian Academy of Sciences.

Basic contents:

Vector map, consisting of 3 thematic layers. Area of distribution and zones of harm are shown by polygons.

Accuracy of the classifier:

Within area of species distribution, two zones of pest damage (moderate and low) have been established according to the extent that agricultural plants are damaged. In the zone of moderate pest damage, T. palliatus causes damage only periodically, in dry springs. Maximum pest damage occurs not more than 2 points in the 5-point scale of harmfulness (Kopaneva et al., 1980). In the zone of low pest damage, beetles are found everywhere, mainly on weeds, but cause little crop damage. The map of area is based on an analysis of the collection of the Zoological Institute. The localities of the species were marked on blank geographical map (Bobrinskii et al., 1969) using standard means of GIS-technologies. Records of the species from Yakutsk and Lower Yenisei River are isolated from the basic area and shown on the map as points. Borders of zones of different harmfulness are given after publications of Petrukha & Butovskii (1947), Zverezomb-Zubovskii (1956), Dobrovol'skii (1959). The zone of moderate pest damage comprises the zone of sugar-beet growing. The zone of low pest damage comprises most of the remaining area, where T. palliatus has no economic significance.

Method of map production:

Scientists were given maps with boundaries of Oblasts and arable lands. After reviewing historic literature, species distribution was hand drawn on maps. If data were on the Oblast-level, distribution is on the Oblast level. In some cases, Oblast.s are further refined by boundaries of the Arable Land Map. Hand drawn maps were scanned, georeferenced and vectorized.
