Notes: [Special Issue: Proceedings of the ISSIS IX International Symposium on Scale Insect Studies held at The University of Padua, Italy, Sept. 2-8, 2001.] A list of 137 scale insects species from Poland, belonging to 9 families is presented. The species that occur in Poland can be divided into three groups: (1) species restricted to the Palaearctic region (106 species, 77.4% of the total fauna), (2) species whose range is limited to 2-3 zoogeographical regions (22 species, 16.0% of the total fauna), (3) cosmopolitan species (9 species, 6.6% of the total fauna). The Palaearctic species are divided into the following subgroups: (a) species widely distributed in the Palaearctic region (50% species, 47.2%), (b) species distributed in two subregions (31 species, 29.2%), (c) species restricted only to Euro-Siberian region (25 species, 23.6%). Among the latter, there are 12 species which occur only in a few countries. A brief comment is given on each group. The ratio of species per genera was also calculated.
