Keywords: Code, geography, world, fauna, bibliography, mapping. The codes used in the Cesa publications have been privately created at the beginning of the year 2000, and the coding idea has been improved to this day. In the present paper, more than 6900 localities, regions, or states are encoded and listed. This list is the most comprehensive one, used in the biogeographical works published up to now. In the publications of the Cesa 2 these codes have been widely used in the database files of the authors especially after 2000. Coverage areas of the codes Faunistical studies : The authors published various faunal lists of the Pterygota orders of the Old World countries at intermediate stages. Faunistical studies are collected under two major groups in the separate database files, i.e., Lepidoptera, and other pterygot orders. All such publications have been based upon the codes selected in the related database files of the authors. Bibliographical studies : Similarly, the authors published various bibliographical lists of the Pterygota orders of the Old World countries at intermediate stages. Geographic interests of such publications have been based upon the codes. Mapping of the species of the ptergot orders: For this purpose, the same codes have been used by using special mapping programs. 1 Asst.
