Ecology. This species is widely distributed throughout Europe, from Turkey in the east to Spain in the west. The most northern populations are in Norway, and the most southern in northern Italy (Pečina, 1975; Wiśniewski & Hirschmann, 1993; and personal observations). Various authors have recorded it from Albania, Austria, Belgium, Czech Republic, France, Germany, Great Britain, Ireland, Poland, Slovakia, Spain, Switzerland, and Ukraine. Kontschán (2003d) recorded this species from Greece but this is likely to be a misidentification, because of the high altitude of this record (2200 m). In Poland, as for other representatives of the genus, C. cassidea is characterised by a low frequency in samples (Fig. 67 A). It prefers marshy forest, mixed forests with spruce, and mixed deciduous forests, and only in these three forest types does its frequency exceed 1%. The distribution of C. cassidea in Poland is related to the distribution of beech (Fagus silvatica), and its optimal altitude is below 400 m a.s.l.
Cilliba circularis Trägårdh, 1931, described from the Faroe Islands, cannot be distinguished from mainland European populations of C. cassidea, including those that we have examined from northern Scandinavia. We believe that C. antennurelloides (Lombardini, 1943), C. foroliviensis Lombardini, 1961, and C. tripliciterscutata Lombardini, 1943, may also be synonymous with C. cassidea, which is common in Italy. However, the descriptions and illustrations of these species are not detailed enough to allow a full comparison, and we have not had the opportunity to examine Lombardini's types.
