ROVARTANI KÖZLEMÉNYEK LVII 1996 pp. 91-96 A new species from the genus Greenisca Borchsenius, 1948 and additional data on the occurrence of scale insects (Homoptera: Coccoidea) in Switzerland F. Kozár and C. Hippe A new species from the genus Greenisca Borchsenius, 1948 and additional data on the occurrence of scale insects (Homoptera: Coccoidea) in Switzerland — In our survey on the occurrence of scale insects in Switzerland 26 species were found, 9 of them being new for her fauna. Some of the new species are well-known, important pests of ornamental plants, e.g., Pseudococcus affinis, P. calceolariae, Acutaspis perseae and Gymnaspis aechmeae. The eriococcid Greenisca erwini Kozár sp. n., however, is a species new for science. With the new data, the total number of scale insect species found in Switzerland so far increased to 130. This indicates that the Swiss fauna still needs further intensive studies. INTRODUCTION The largest survey on the occurrence of scale insects in Switzerland was carried out by Kozár et al. (1994). These authors found 87 species, bringing the total number known to occur in this country to 115. Danzig (1994) collected seven additional species. Our work represents a continuation of the studies. MATERIAL AND METHODS The insects found were described according to the method of Kozár et al. (1994). Most of them were collected by the senior author in 1993, specimen from Geneva and Fribourg by S. Fischer in 1994. In these cases the year of collecting is not mentioned in the following list. For material from other sources, however, all details are given. Our samples are deposited as microscopic slides at the Plant Protection Institute, Hungarian Academy of Sciences in Budapest. RESULTS In our survey the eriococcid Greenisca erwini Kozár sp. n. was found, a species new for science. In addition, the following 25 species were collected, among them 9 species which were new for the fauna of Switzerland (marked with an asterisk). In total, 130 scale insect species are known from this country so far.
