two sizes (5.3 um wide-22.6 um long and 11.5 um wide-28.4 um long, respectively), numerous on dorsal and ventral surfaces. Microtubular ducts (4.3 \im long) in large numbers on dorsum. Ventral body margin with cruciform pores. Venter of thorax with scattered five-locular pores (4.3 u.m in diameter), venter of abdomen with five- and multilocular pores (5.4 u.m in diameter). Dorsum of body with especially thick-walled five-locular (sometimes three1 ocular) pores in large numbers (6.0 um in diameter), but not arranged in groups. The species is named in honour of Dr. Erwin Mani, acknowledging his great contribution to research on scale insects in Switzerland. Remark: The classification of the genera in the family Eriococcidae is controversial among scientists (Borchsenius 1949, Danzig 1980, Koteja and Zak-Ogaza 1981, Kozár 1983, Williams 1985, Kosztarab and Kozár 1988, Miller and Miller 1992, 1993). By a narrow sense of a genus (Koteja and Zak-Ogaza 1981), the new species could be separated from the others and placed in a new genus, based on the row of spines along the body margin and its thick-walled five-locular pores (not arranged in special groups) on the dorsum. By a broad sense of a genus, however, this combination of characters could as well fuse several genera (as Acanthococcus Signorét, 1875; Rhizococcus Signorét, 1875; Greenisca Borchsenius, 1948; Anophococcus Balachowsky, 1954; Gregoporia Danzig, 1979 and Kaweckia Koteja et Zak-Ogaza, 1981) in just one genus. The only species from the Nearctic region, Acanthococcus stellatus (McDaniel, 1963), has thickwalled five-locular pores on the dorsum, but no spines on the margin of the body. At the present stage of knowledge of the eriococcid fauna we decided to place the new species in the oldest genus Greenisca (having thick-walled five-locular pores) and neither to describe a new genus nor to fuse different genera. This new species again calls the attention to the special fauna of the Gersau-Oberholz region (Rézbányai-Reser 1984, Kozár et al. 1994). IV.
