FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK XLVI. 2 1985 p. 63-110 Check-list of the Palaearctic Coccoidea (Homoptera) By F. KOZÁR and J. WALTER (Received 22 November, 1984) Abstract: The authors completed the first check-list of Palaearctic Coccoidea and included 1938 species in it. Two generic and one species name proved to be homonymous, therefore they were given new names. New combinations were necessary for 98 species (39 Pseudococcidae, 38 Eriococcidae and 21 Asterolecaniidae). Among insects, coccids constitute the group comprising several of the most destructive pests. The economic importance alone emphasizes the necessity of more correct information about the taxonomy of species belonging in this group. It is unfortunate, however, that the last comprehensive catalogue of species was published more than 80 years ago (FERNALD, 1903). No such catalogue for the Palaearctic Region has ever been published, with the exception of LINDINGER'

s (1912) monography about the scale insect species of Europe and its confines.Recently, world catalogues for the families Conchaspididae, Diaspididae, Eriococcidae, Kerridae have also appeared. Still, there is no available contemporary work of reference for the majority of families. Such a hiatus places extreme burdens even on specialists in getting a contextual view of coccids, let alone the many applied entomologists. We think, it is timely to prepare catalogues for scale insect families or for geographical regions. This idea was already raised in 1983, at the 4th International Scale-Insect Symposium, Budapest. However, the participants came to the conclusion that for the time being the demand for a world catalogue is premature. The situation is not much different in respect of the larger families, too. A possible solution would be first to prepare regional check-lists or family-world lists, then on the basis of these to complete a regional catalogue. The present paper is the first contribution in the above sense. It includes the whole Palaearctic Region and follows EMELYANOV*

s (1974) areal division i.e. in Africa the borderline is the Tropic of Cancer, in Asia It comprises China, but excludes South China, and in Japan it takes the areas north of the 30° latitude. For the compilation of the species-list, the following sources and information were used: reprints received from colleagues, earlier catalogues by FERNALD (1903 + supplements), HOY (1963), BORCHSENIUS (1966), BEN-DOV (1981); data available from books and papers listed by bibliographies in MORRISON and RENK (1957), MORRISON and MORRISON (196 5), RUSSELL, KOSZTARAB and KOSZTARAB (1974) (full citations are given therein), and the speciesname lists of the scale insect collection of the British Museum of Natural History which has been constructed on the base of the Zoological Record and other abstracting periodicals, as well as species-lists relevant to a given country and completed but not published by colleagues: China (WANG, 1982a),
